Neo MCP Server
@r3e/neo-mcp is an MCP server for Neo N3 blockchain queries and controlled, auditable transaction submission. It ships three entrypoints:
Entrypoint | Command | Protocol |
MCP stdio |
| MCP over stdin/stdout, for local clients such as Claude Desktop and Cursor |
MCP HTTP |
| MCP 2026-07-28 stateless HTTP, for remote MCP clients |
REST API |
| Bespoke REST/JSON; not an MCP transport |
The two HTTP servers are unrelated and configured separately. See Remote MCP 2026 HTTP and docs/remote-mcp-transport.md.
Current version: 4.1.0. Node.js >=22 is required. Version 4 speaks only
MCP 2026-07-28; clients using the removed initialization/session protocol are
rejected rather than downgraded.
Quick Start
Install and run the MCP stdio server:
npm install -g @r3e/neo-mcp
neo-mcpOr run it without a global install:
npx -y @r3e/neo-mcpExample Claude Desktop or Cursor configuration:
{
"mcpServers": {
"neo-n3": {
"command": "npx",
"args": ["-y", "@r3e/neo-mcp"],
"env": {
"NEO_NETWORK": "testnet",
"NEO_TESTNET_RPC": "https://testnet1.neo.coz.io:443",
"LOG_LEVEL": "info"
}
}
}

Programmatic API
The package root exports the MCP server, HTTP server, services, network enums, and validated configuration:
import { NeoNetwork, NeoService } from '@r3e/neo-mcp';
const neo = new NeoService(
'https://testnet1.neo.coz.io:443',
NeoNetwork.TESTNET,
);
const blockCount = await neo.getBlockCount();
console.log({ blockCount, height: Math.max(0, blockCount - 1) });NeoMcpServer exposes run() and close() for applications that manage the stdio transport lifecycle themselves.

The aliases NEO_MAINNET_RPC_URL, NEO_TESTNET_RPC_URL, and NEO_NETWORK_MODE remain supported.
Remote RPC endpoints must use HTTPS. Plain HTTP is accepted for loopback RPC endpoints; setting NEO_ALLOW_INSECURE_RPC=true explicitly permits remote plaintext HTTP and should be limited to controlled development environments.
When NEO_NETWORK=both, read-only MCP calls without an explicit network use mainnet. Every state-changing call requires an explicit network and an idempotency key. The HTTP entrypoint rejects both; set NEO_NETWORK=mainnet or NEO_NETWORK=testnet.
Writes are disabled by default. To enable them, create an owner-only signer file outside the repository and configure durable state:
install -m 0600 /dev/stdin /run/secrets/neo-signer-wif
export NEO_ENABLE_WRITES=true
export NEO_SIGNER_WIF_FILE=/run/secrets/neo-signer-wif
export NEO_WRITE_STATE_DIR=/var/lib/neo-mcp/write-operations
export NEO_MCP_REQUEST_STATE_KEY="$(openssl rand -hex 32)"
export HTTP_WRITE_APPROVAL_API_KEY="$(openssl rand -hex 32)"The MCP and HTTP request schemas never accept WIFs, private keys, or passwords.
MCP writes use the 2026-07-28 input_required flow. The server signs the
opaque requestState, binds it to tools/call, expires it after ten minutes,
and executes only after the re-entered response accepts the exact intent
fingerprint. HTTP writes return a pending intent and require a separate approval
request authenticated by HTTP_WRITE_APPROVAL_API_KEY.
Account intelligence remains evidence-first: analyze_account_graph exposes
the replayable, network-scoped transfer graph and curated metadata only. The
backend's deterministic exchange-sweep, coordinated-signer,
community-affinity, and graph-similarity detector queue is deliberately not
exposed as public identity data; pending candidates require human review before
they can become curated metadata.
As of 2026-08-01, both production network detector timers have completed their
detector rerun successfully. The resulting pending queue is operational review
evidence only and is not returned by analyze_account_graph.
HTTP API
This is a bespoke REST/JSON API, not an MCP transport. MCP clients cannot connect to it; they use the stdio entrypoint or the remote MCP transport.
Build and start the HTTP entrypoint:
npm ci
npm run build
export HTTP_API_KEY="$(openssl rand -hex 32)"
NEO_NETWORK=mainnet npm run start:httpThe server listens on 127.0.0.1:3000 by default. A non-loopback HTTP_HOST requires HTTP_API_KEY, and every configured API key must contain at least 32 bytes. When a key is configured, send it as a bearer token on every route except GET /live and GET /health:
curl http://127.0.0.1:3000/live
curl http://127.0.0.1:3000/health
curl -H "Authorization: Bearer $HTTP_API_KEY" \
http://127.0.0.1:3000/api/blockchain/heightThe HTTP listener does not terminate TLS. Plaintext HTTP is supported only on loopback or a trusted host-local proxy network. Remote clients must use HTTPS through a TLS-terminating reverse proxy or load balancer; direct remote plaintext HTTP is unsupported because bearer tokens traverse requests.
The height endpoint distinguishes the node's block count from the latest block index:
{
"blockCount": 12346,
"height": 12345
}HTTP_CORS_ORIGINS is an optional exact-origin allowlist. For example:
HTTP_CORS_ORIGINS=https://console.example.com,https://admin.example.comOrigins must use HTTP or HTTPS and cannot contain paths, credentials, query strings, or fragments. Wildcard CORS is not supported.
POST and PUT bodies must be JSON objects. The default body limit is 1 MiB and can be changed with HTTP_MAX_BODY_BYTES. A write request creates an immutable pending intent:
curl -X POST http://127.0.0.1:3000/api/transfers \
-H "Authorization: Bearer $HTTP_API_KEY" \
-H "Idempotency-Key: transfer-2026-07-11-001" \
-H 'Content-Type: application/json' \
-d '{"network":"mainnet","toAddress":"Nb...","asset":"NEO","amount":"1"}'Approve only after comparing the returned fingerprint with the intended request:
curl -X POST http://127.0.0.1:3000/api/write-intents/INTENT_ID/approve \
-H "Authorization: Bearer $HTTP_WRITE_APPROVAL_API_KEY" \
-H 'Content-Type: application/json' \
-d '{"fingerprint":"RETURNED_64_HEX_FINGERPRINT"}'See API.md for the tool and route reference.
Remote MCP 2026 HTTP
The stateless MCP 2026-07-28 HTTP transport serves the same non-custodial MCP
surface as the stdio entrypoint to remote clients. It is a separate process from the
REST API, listens on its own port, and has its own configuration and bearer
token. The only default external side effect is request_account_watch, which
is disabled unless explicitly configured and can only send a double-opt-in
verification message; it cannot activate a subscription.
npm ci
npm run build
export MCP_HTTP_BEARER="$(openssl rand -hex 32)"
NEO_NETWORK=mainnet npm run start:mcp-httpThe server listens on 127.0.0.1:3001 by default and exposes:
Method | Path | Purpose |
|
| Stateless MCP |
|
| CORS preflight |
|
| Unauthenticated liveness probe |
A non-loopback MCP_HTTP_HOST requires MCP_HTTP_BEARER and rejects a token shorter than 32 bytes, mirroring the HTTP_API_KEY rule for the REST entrypoint. When a token is configured, clients send Authorization: Bearer <token> on every request to MCP_HTTP_PATH; /healthz stays unauthenticated so probes can reach it.
Connect with the MCP TypeScript SDK:
import {
Client,
StreamableHTTPClientTransport,
} from '@modelcontextprotocol/client';
const transport = new StreamableHTTPClientTransport(new URL('http://127.0.0.1:3001/mcp'), {
authProvider: { token: async () => process.env.MCP_HTTP_BEARER },
});
const client = new Client(
{ name: 'my-client', version: '2.0.0' },
{
capabilities: {},
versionNegotiation: { mode: { pin: '2026-07-28' } },
},
);
await client.connect(transport);
const { tools } = await client.listTools();Like the REST listener, this listener serves plaintext HTTP and does not terminate TLS. Remote clients must reach it through a TLS-terminating reverse proxy. Requests are stateless, so replicas do not need sticky routing.
See remote-mcp-transport.md for the full configuration reference, an end-to-end local run against the Neo Explorer agent, production deployment guidance, and troubleshooting.
Docker
The production Compose file is docker/docker-compose.yml. It defines two services from the same image: neo-mcp runs the REST API on port 3000, and neo-mcp-http runs the remote MCP transport on port 3001. Each requires its own token, binds the host port to 127.0.0.1 by default, and persists wallet records in its own volume:
export HTTP_API_KEY="$(openssl rand -hex 32)"
export MCP_HTTP_BEARER="$(openssl rand -hex 32)"
docker compose -f docker/docker-compose.yml up -dStart only the remote MCP service. Compose interpolates the whole file before
selecting a service, so the REST service's mandatory HTTP_API_KEY must be set
to any non-empty placeholder even though its container is never started here
(the ">= 32 bytes" check only runs when that container actually starts):
HTTP_API_KEY=unused-when-starting-only-the-mcp-service \
MCP_HTTP_BEARER="$(openssl rand -hex 32)" \
docker compose -f docker/docker-compose.yml up -d neo-mcp-httpTo run a published image instead of building the checkout, use the digest-only registry overlay with the image repository and the release artifact's 64-character lowercase hexadecimal digest:
NEO_MCP_IMAGE_REPOSITORY=r3enetwork/neo-mcp \
NEO_MCP_IMAGE_DIGEST=0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef \
HTTP_API_KEY="$HTTP_API_KEY" \
MCP_HTTP_BEARER="$MCP_HTTP_BEARER" \
docker compose -f docker/docker-compose.yml \
-f docker/docker-compose.registry.yml up -dSet HTTP_BIND_ADDRESS=0.0.0.0 (REST) or MCP_HTTP_BIND_ADDRESS=0.0.0.0 (remote MCP) only when the service must be reachable by a TLS-terminating reverse proxy or load balancer. Do not expose either plaintext listener directly to remote clients.
The development Compose file binds locally and supplies local-development tokens by default. It defines neo-mcp-dev for the REST API and neo-mcp-http-dev for the remote MCP transport:
docker compose -f docker/docker-compose.dev.yml up -dThose default tokens are for local development only. Override HTTP_API_KEY and MCP_HTTP_BEARER for any shared environment.
Build and run without Compose:
npm run docker:build
export HTTP_API_KEY="$(openssl rand -hex 32)"
npm run docker:run -- --detachSee DOCKER.md for image, volume, and helper-script details.
MCP Tools and Resources
The default MCP surface exposes 58 non-custodial tools. Every tool that both chains implement takes a required chain discriminator, "n3" or "neox", with no silent default; single-chain tools reject the chain they do not serve. The network parameter is always "mainnet" or "testnet"; the registry rewrites it for Neo X internally, so callers never spell out a chain-qualified network name.
Server and data utilities:
get_network_mode,get_wallet,inspect_neo_value,convert_neo_data,get_neo_service_info,analyze_stablecoinsChain, both chains:
get_chain_info,get_block_height,get_block,get_transaction,get_transaction_status,get_balanceContracts, both chains:
call_contract,get_contract_info,simulate_callConstruct, both chains:
build_transfer,build_contract_callNeo ecosystem reads:

request_account_watchsends a cooldown-limited verification message for one explicit Neo N3 network, address, and email. It is non-destructive and idempotent; the watch remains inactive until the recipient confirms in the Explorer.Neo N3 only:
get_application_log,wait_for_transaction,get_unclaimed_gas,get_nep17_transfers,get_nep11_balances,get_nep11_transfers,get_contract_status,list_famous_contracts,estimate_transfer_fees,estimate_invoke_fees,explorer_list_address_assets,query_explorer_findNeo X only:
analyze_neox_transaction,analyze_neox_block,analyze_neox_address,analyze_neox_contract,analyze_neox_token,query_explorer_graphql
call_contract is strictly read-only: invokefunction on Neo N3, eth_call on Neo X. The build_* tools run the exact read-only simulation and return UNSIGNED transaction proposals for a wallet to review and sign; no default-surface tool holds a key, signs, or broadcasts. build_vote pins the native NEO contract, while build_nns_operation pins the network-correct NameService contract and operation arguments.
query_neofs requires an explicit network field. The selected N3 network is preserved as
address context in the result, while the fixed NeoFS gateway remains global; this prevents
the assistant from presenting a mainnet/testnet N3 context as a NeoFS gateway switch.
Constructed N3 and Neo X proposals are returned with an unsigned-only boundary and are
simulated before the Explorer exposes them to a wallet.
Explorer AI roadmap
The canonical cross-repository plan is maintained in the Neo OS Fura AI Plan and Roadmap. Neo MCP is the typed orchestration boundary: it exposes deterministic Explorer evidence and unsigned, simulated proposals to the assistant while keeping wallet review, signing, and broadcasting outside the hosted MCP service.
analyze_transaction is the primary Neo N3 investigation tool. Its v2 response
adds stable evidence IDs, bounded counts, exact grouped fund flows,
conservative failure classification, and code-based findings. Clients should
cite those IDs, preserve exact decimal strings, and disclose when detailed
opcode or storage traces are unavailable.
investigate_transactions composes one to twelve confirmed Neo N3
transactions into a deterministic, immutable evidence set. It returns a
block-ordered timeline, complete per-transaction analyses, and observed asset
relationships with source transactions, evidence references, confidence
classes, and the requested_transactions_only sampling boundary. It does not
infer shared ownership, causality, hidden calls, or activity outside the set.
analyze_contract is the primary Neo N3 contract-intelligence tool. Its v1
response returns network-scoped ABI, Manifest permission and trust, NEF method
token, compiler, update, and source-verification facts with stable evidence
IDs. Clients must keep declared source URLs, safe=false ABI methods,
deterministic static findings, verified source, simulation, and vulnerability
claims distinct.
inspect_contract_code is the paginated code-inspection companion. It returns
bounded NeoVM operands, resolved syscall names, ABI method ownership, and
static control-flow targets with stable opcode evidence IDs. It is deterministic
disassembly, not a runtime trace, verified source, decompilation, or simulation.
analyze_contract_upgrades compares immutable indexed contract artifacts by
update counter. It reports exact complete or partial historical coverage,
SHA-256 artifact identities, and structural ABI method/event/standard changes.
Missing versions are never synthesized, and storage compatibility remains
not_determined because manifest and NEF artifacts cannot prove a storage
layout.
get_contract_source_verification returns the immutable reproducibility record
for each verified update counter: source bundle digest, immutable repository
commit, compiler settings, and exact manifest, NEF, binary, and script hashes.
Only a record for the current update counter verifies current code. Exact
artifact equality is not a security audit.
A locally launched stdio server with NEO_ENABLE_WRITES=true,
NEO_SIGNER_WIF_FILE, and NEO_MCP_REQUEST_STATE_KEY registers four
additional Neo N3 tools that sign with that owner-supplied key:
transfer_assets, invoke_contract_write, claim_gas, deploy_contract.
They require an idempotencyKey, an explicit network, a modern client that
can fulfil an embedded form request, and acceptance of the exact returned
intent fingerprint through input_required. The MCP HTTP transport is
read-only by design and ignores the setting.
The curated contract list is intentionally empty until each entry has a current network hash and a verified on-chain manifest. Generic contract tools accept a script hash, Neo address, exact N3Index name, or a name learned from a live manifest.
estimate_transfer_fees and estimate_invoke_fees return exact integer decimal strings in networkFeeDatos and systemFeeDatos, plus formatted GAS strings in networkFeeGas and systemFeeGas. Before any transaction is signed or broadcast, the combined system and network fee must not exceed NEO_MAX_TRANSACTION_FEE_GAS.
deploy_contract accepts compiler output as a complete serialized NEF object, nef: { encoding: "hex" | "base64", data: string }, together with its manifest. Raw VM bytecode is not a deployable NEF artifact.
get_block_height returns both blockCount and height, where height is max(0, blockCount - 1).
For Neo N3 block analysis, pass includeStateRoot: true to get_block to
receive the exact StateService root plus local and StateValidator-validated
height boundaries. The returned validated flag is true only when the requested
root is at or below the validated boundary. Neo X rejects this N3-only option,
and ordinary block lookups do not incur the extra RPC calls. Neo N3 block
responses also include a deterministic ISO-8601 timeIso alongside the node's
millisecond time value.

Security Notes
Keep both HTTP listeners bound to loopback unless remote access is required.
Terminate TLS before every remote HTTP connection; a bearer token authenticates requests but does not encrypt itself in transit.
Use a randomly generated token of at least 32 bytes for
HTTP_API_KEYandMCP_HTTP_BEARER.Keep
NEO_ENABLE_WRITES=falseon any remotely reachable MCP listener; the remote transport must never carry a transaction signer.Keep
EXPLORER_ACCOUNT_WATCH_ENABLED=falseunless the deployment intentionally supports verification email. When enabled, use a dedicated 32-byte-or-longerEXPLORER_ACCOUNT_WATCH_API_TOKENthat differs from every transport/API bearer.Keep the signer WIF only in the owner-only
NEO_SIGNER_WIF_FILE; never send it through MCP or HTTP.Persist
WALLETS_DIRon controlled storage with restrictive permissions.State-changing MCP tools require an explicit
network, a stable idempotency key, and an exactinput_requiredapproval whose request state passes HMAC, expiry, method-binding, intent, network, operation, and fingerprint checks.Remote plaintext HTTP RPC endpoints are rejected unless
NEO_ALLOW_INSECURE_RPC=true; prefer HTTPS.Signed transactions are rejected when their combined system and network fees exceed
NEO_MAX_TRANSACTION_FEE_GAS.Rate limiting is enabled by default outside test-like environments.
Testing
# Deterministic unit tests; excludes tests/mcp-*.test.ts
npm run test:unit
# Compile, then run deterministic built-server smoke and lifecycle checks
npm run build
npm run test:mcp
# Unit tests + build + deterministic MCP checks
npm run test:all
# Opt-in public RPC checks; requires a build and network access
npm run build
npm run test:mcp:live
# Explicit stress suite; requires a build
npm run test:mcp:stressnpm run test:integration is an additional built-server integration script that calls public RPC endpoints; it is not part of test:all.
Release and Dependency Checks
npm audit and npm audit --omit=dev are expected to pass. The package uses a scoped lodash@4.18.1 override for the transitive @cityofzion/neon-core dependency.
./scripts/prepare-release.sh installs the lockfile, runs type checking, deterministic tests, the build, both audits, package validation, Compose validation, and container builds. It updates the version only after verification and does not create a commit or tag.
GitHub Actions tests Node.js 22 and 24. Published GitHub releases can publish the npm package and Docker image when the required repository secrets are configured; no production deployment target is defined in this repository.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description must fully disclose behavior. It only states 'estimate fees' without explaining what this entails (e.g., simulation, return format, side effects). Minimal behavioral context is provided.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence is concise but overly brief. It conveys the core function without waste, but lacks structure or front-loading of critical details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, yet description omits return value clues. With 8 parameters, it fails to guide which to use for different scenarios (e.g., contract vs nameOrHash vs scriptHash). Incomplete for the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage, so parameters are documented. The description adds 'by script hash or generic contract reference' which aligns with multiple parameter options, but does not clarify relationships or preferred usage among them.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool estimates network and system fees for contract invocations, specifying that it can use a script hash or generic contract reference. However, it does not explicitly distinguish from the sibling 'estimate_transfer_fees' tool, which is inferred but not stated.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. The name suggests contract invocation fee estimation, but no conditions, prerequisites, or exclusions are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
estimate_transfer_feesB
Estimate network and system fees for a transfer.
| Name | Required | Description | Default |
|---|---|---|---|
| asset | Yes | Asset hash | |
| amount | Yes | Amount | |
| network | No | Optional: Network | |
| toAddress | Yes | Recipient address | |
| fromAddress | Yes | Sender address |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description does not disclose behavioral traits (e.g., idempotency, side effects, permissions). Fails to add value beyond the basic purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded, and concise with no unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Lacks description of return values (no output schema), which is essential for an estimation tool. Could mention that it does not execute a transfer.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage; description adds no extra meaning to parameters beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool estimates network and system fees for a transfer, distinguishing it from sibling `estimate_invoke_fees` which estimates invocation fees.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage for fee estimation before transfers but no explicit guidance on when to use this versus alternatives like `estimate_invoke_fees` or `transfer_assets`.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_application_logA
Get the application log for a transaction hash.
| Name | Required | Description | Default |

No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, side effects, or required permissions. The description's single sentence does not compensate for the lack of transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with no wasted words. It is appropriately sized for the simple functionality.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple log retrieval tool with no output schema, the description is minimal but adequate. However, it does not hint at the log content or return format, which could be useful for agents.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% coverage with descriptions for both parameters ('txid' and 'network'). The description adds no additional meaning beyond what the schema provides, meeting baseline expectations.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get the application log for a transaction hash.' It uses a specific verb and resource, and distinguishes from sibling tools like 'get_transaction' which returns different data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for retrieving logs for a transaction but provides no explicit guidance on when to use this tool versus alternatives or any exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_balanceA
Get NEO, GAS, and NEP-17 balances for an address.
| Name | Required | Description | Default |
|---|---|---|---|
| address | Yes | Neo N3 address | |
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single sentence conveys the entire purpose efficiently with no wasted words. It is front-loaded and easy to parse.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple and the description covers the essential purpose. However, without an output schema, the return format is undefined, and the description does not elaborate on the structure of the balances. Adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds value by listing specific token types (NEO, GAS, NEP-17), which is not in the schema. The schema already fully describes parameters, so baseline is 3; the extra detail raises it to 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it gets NEO, GAS, and NEP-17 balances for a given address. The verb 'get' and resource 'balances' are specific, and it distinguishes from sibling tools like get_nep11_balances.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as get_nep17_transfers or get_nep11_balances. The description lacks any contextual cues for selection.

| hashOrHeight | Yes | Block hash (64 hex chars) or block height (number) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It does not disclose behavioral traits like error handling for invalid hash/height, network fallback behavior, or size limits. The verb 'Get' implies read-only, but more is needed for transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence that front-loads the purpose. While very short, it contains no filler. However, it could be considered under-specified rather than concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description should mention what the returned 'block details' include (e.g., all fields, transactions). The absence makes it somewhat incomplete for an AI agent to fully understand the output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description adds no new meaning beyond the schema's parameter descriptions, which already explain the hash/height distinction and optional network parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Get' and the resource 'block details', and specifies the lookup method 'by height or hash'. This distinguishes it from siblings like get_blockchain_info or get_block_count, though it doesn't detail what 'details' includes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a description for the single parameter. The tool description adds no additional meaning beyond what the schema already provides, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Get' and the specific resources: blockchain height, validator info, and active network. It is distinct from sibling tools like get_balance or get_block.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit when-to-use or when-not-to-use guidance. However, the purpose implies use for overall blockchain state, but no comparison to siblings like get_network_mode or get_block_count.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_block_countB
Get the block count and latest block height for the selected network.
| Name | Required | Description | Default |
|---|---|---|---|
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It only states the tool retrieves data but fails to mention side effects, permissions, rate limits, or response structure. The lack of any safety or mutation context is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single, front-loaded sentence that wastes no words. Every part is essential, and the structure is optimally concise for quick parsing.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (1 parameter, no output schema), the description adequately conveys the return value (block count and height). Minor ambiguity around 'block count' (whether it is total or something else) prevents a perfect score, but it is otherwise complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% and fully describes the 'network' parameter (mainnet or testnet). The description adds no additional meaning beyond 'selected network', so it meets the baseline of 3 without improvement.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the tool returns 'block count and latest block height' for the selected network, clearly distinguishing it from siblings like 'get_block' (returns a specific block) and 'get_blockchain_info' (returns broader chain info). Verb 'Get' plus resource 'block count and height' is specific and unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as 'get_block' or 'get_blockchain_info'. The description does not specify context or prerequisites, leaving the agent to infer usage from the name alone.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no wasted words. However, could include more useful details without being verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, no annotations, and description does not explain what 'metadata and operations' entails or the response format. Four optional parameters with no required ones may confuse an AI agent on what to provide.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% description coverage, but the description merely restates the identification methods without clarifying the redundancy or relationship between the three similar parameters (contract, contractName, nameOrHash). Adds no meaningful information beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (Get), the resource (sanitized metadata for a locally stored wallet), and the parameter (by address). It effectively distinguishes from sibling tools like create_wallet or import_wallet.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide explicit when-to-use or when-not-to-use guidance. While it implies use for retrieving wallet metadata, it lacks alternatives or exclusions compared to siblings like import_wallet.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
invoke_contractB
Run a read-only smart contract invocation without signing or broadcasting a transaction.
| Name | Required | Description | Default |
|---|---|---|---|
| args | No | Method arguments as an array of values | |
| network | No | Network to query | |
| contract | No | Contract reference: script hash, Neo address, exact N3Index name, or a previously discovered manifest name | |
| operation | Yes | Contract method name to invoke | |
| nameOrHash | No | Contract name or script hash (alias for contract) | |
| scriptHash | No | Contract script hash (40 hex chars, optional 0x prefix) | |
| contractName | No | Exact contract name resolved through N3Index or a live manifest |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states it is read-only and non-broadcasting, clarifying it is non-destructive. However, with no annotations provided, it fails to disclose other behavioral aspects like error handling, result structure, or limits. The read-only trait is the key behavioral detail, earning a 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single concise sentence conveys the core purpose with no redundancy. However, it could be slightly more structured (e.g., separate lines for key details) without losing brevity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of 7 parameters and no output schema, the description is too minimal. It does not explain how to use multiple contract identifiers, expected output format, or error conditions. For a tool of this complexity, more context is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the descriptions in the schema already document all parameters. The tool description adds no extra meaning beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: performing a read-only contract invocation without signing or broadcasting. This precisely distinguishes it from other tools like estimate_invoke_fees or get_contract_info.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, nor does it explain which parameter among the multiple contract identifiers (contract, nameOrHash, scriptHash, contractName) should be used in different scenarios. Required parameter 'operation' is mentioned in schema but not in description context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
list_famous_contractsB
List supported well-known contracts for the selected network.
| Name | Required | Description | Default |
|---|---|---|---|
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. Description does not disclose behavioral traits like auth requirements or data freshness. Only states basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, efficient and to the point with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Description is minimal. Does not explain what 'famous contracts' are or if the list is dynamic. Agent may lack full context for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers the parameter with description of allowed values. Description adds no new semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it lists supported well-known contracts for a selected network, with verb and resource. It distinguishes from sibling tools like deploy_contract or get_contract_info.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives. No context on prerequisites or network availability.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
wait_for_transactionC
Wait for a transaction to be confirmed on-chain.
| Name | Required | Description | Default |
|---|---|---|---|
| txid | Yes | Transaction hash (64 hex chars, optional 0x prefix) | |
| network | No | Optional: Network | |
| timeoutMs | No | Optional timeout in milliseconds | |
| pollIntervalMs | No | Optional polling interval in milliseconds | |
| includeApplicationLog | No | Include the application log once the transaction confirms |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It fails to disclose polling behavior, timeout consequences, or side effects. The fact that it waits is implied but not detailed (e.g., does it block until confirmed or return immediately?).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with no wasted words. However, given the lack of annotations, the description is too short to convey necessary behavioral information; conciseness could be improved with more context.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, 5 parameters, and no annotations. The description does not explain return value, error conditions, or how parameters like timeoutMs affect behavior, leaving the agent with significant gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% description coverage for parameters, so description adds no additional meaning. Baseline score of 3 is appropriate since the schema already explains each parameter's purpose.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool waits for a transaction to be confirmed, using specific verb and resource. However, it does not differentiate from siblings like get_transaction which could also check confirmation status.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., get_transaction for one-time check). The description lacks context about prerequisite conditions or post-conditions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Each tool has a clearly distinct purpose. For example, get_balance, get_nep11_balances, and get_nep17_balances are separated by token standard; get_contract_info and get_contract_status are distinguished by metadata vs. status. No significant overlap.
All tool names use snake_case and follow a consistent verb_noun pattern (e.g., get_balance, create_wallet, deploy_contract). No mixing of conventions.
27 tools is slightly above the typical 3-15 range but still reasonable given the broad scope covering wallets, contracts, tokens, blocks, NeoFS, and fees. It feels a bit heavy but not excessive.
The toolset covers major workflows like wallet management, asset transfers, contract deployment/invocation, and blockchain queries. Minor gaps exist, such as missing contract update or token metadata retrieval, but the core functionality is well-covered.
