"Exploring OpenAPI/Swagger Specifications" matching MCP tools:

• payment_offer_preflightA

  x402-data-gatewayA

  Compare x402 and MPP payment challenges, terms, and seller-declared JSON success-response readiness for one exact public HTTPS GET route before buyer authorization, including URL and realm binding, expiry, cross-protocol economic parity, and exact-route OpenAPI evidence. Use `agent_discoverability_audit` instead when you need to know whether catalogs rank or expose a service. This tool uses no target credential, signature, or target payment, follows no redirect, never reads the paid target body, and reads only the same-origin public OpenAPI document under a strict size cap. A seller declaration is advisory and does not establish runtime validity, seller trust, utility, or settlement reliability.

• get_vehicle_detailsA

  FINN Auto - Car SubscriptionA

  Get full specifications, equipment, all images, and pricing per term for a specific vehicle. Use a vehicle_id from search_vehicles results. IMPORTANT: Always show `detail_url` as a clickable link — it points to the FINN configurator where the user picks term and km. To produce a direct checkout link for a specific term + km combination (and optionally a one-time Fahrzeugbereitstellung), call `get_subscription_pricing` and use the `checkout_url` it returns. Never construct checkout URLs yourself. The `vehicle_id` field is an internal API identifier — never display it to users.

• faa_search_aircraft_typesA

  faa-aircraft-registry-mcp-serverA

  Search FAA aircraft types by manufacturer/model name, aircraft type code, or category code to discover 7-character manufacturer/model/series codes and browse specifications. Use this before faa_get_aircraft_type to find a code by name. At least one filter is required. Every response reports totalCount (all matches, not just this page); when more remain, it returns nextOffset — pass it back as offset to page forward.

• factreason_integration_briefA

  FactReasonA

  Compile one callable third-party API brief: base URL, auth scheme, required parameters and types, request body, and documented response codes. Service is required and endpoint optionally narrows the operation. Set responseFormat="compact" for tokenizer-measured context savings; the backward-compatible default returns the full brief plus compact form. Uses metered access. Prefer factreason_api_schema when exploring multiple endpoints.

  ConnectorNo auth

• list_dropsA

  Real Real GenuineB

  [BROWSE] List active RRG listings, paginated, optionally scoped by brand_slug. Use when exploring the catalogue without a specific item in mind. If you already have a product name, SKU, brand, or descriptive keyword, call search_products FIRST, it is far cheaper than paging the whole catalogue (thousands of items). Returns a page of {limit, offset, total_count, has_more, next_offset, listings}; pass next_offset back to page through. Each listing has title, price in USDC, edition size, and remaining supply. Live on-chain minted count is in get_drop_details, not here. Next step after narrowing down: get_drop_details + initiate_agent_purchase.

  ConnectorNo auth

• describe_live_connectorA

  Power Automate MCP Server by Flow StudioA

  Describe a live Power Platform connector/API and its operations. Aligned with Canvas MCP describe_api. Use mode=summary (default) to get a compact operation catalog. Use operationId to describe one operation, including inputs, outputs, dynamic parameter metadata, nextTool hints to call get_live_dynamic_options, and an authored hint + canonical example shape (when one exists) to copy into update_live_flow. Use search without connectorName/apiName to search operations across connectors and get connection-aware suggestions. Use mode=full only when raw OpenAPI connector metadata is required.

  ConnectorNo auth

• t54_list_operationsA

  Agentic Swarm Marketplace (T54 x402 MCP)B

  Returns operationIds, HTTP methods, paths, and query parameter names from the bundled OpenAPI spec (no network). Use before t54_x402_request or per-SKU tools.

  Real Real GenuineA

  [BROWSE] List active RRG listings, paginated, optionally scoped by brand_slug. Use when exploring the catalogue without a specific item in mind. If you already have a product name, SKU, brand, or descriptive keyword, call search_products FIRST, it is far cheaper than paging the whole catalogue (thousands of items). Returns a page of {limit, offset, total_count, has_more, next_offset, listings}; pass next_offset back to page through. Each listing has title, price in USDC, edition size, and remaining supply. Live on-chain minted count is in get_drop_details, not here. Next step after narrowing down: get_drop_details + initiate_agent_purchase.

• check_urlA

  Not Human SearchA

  On-demand agentic-readiness check for any URL. Runs the NHS 7-signal crawler live (llms.txt, ai-plugin.json, OpenAPI, structured API, MCP server, robots.txt AI rules, Schema.org) and returns a score 0-100 with per-signal breakdown. Use before calling an unfamiliar API to confirm it's agent-usable. Re-runnable without the submissions-table side-effect of submit_site — ideal for verify-before-use workflows.

  ConnectorNo auth

• get_endpoint_schemaA

  nordic-dataA

  Discovery meta-tool. Returns the full parameter and response schema for a single Nordic Data API endpoint (path + method), read from the backend's live OpenAPI spec with $refs resolved inline. Use after list_endpoints to learn exactly which parameters an endpoint takes before calling it with call_endpoint. Admin endpoints are rejected.

  ConnectorNo auth

• get_apiA

  Apis GuruA

  Get the full directory entry for one API by its exact APIs.guru name/key (e.g. "stripe.com" or "googleapis.com:calendar"). Returns every version of that API with its info (title, description, provider, categories), last-updated date, docs link, and OpenAPI/Swagger spec URLs (swaggerUrl JSON + swaggerYamlUrl YAML), plus which version is preferred. Use this once you know the exact name (from search_apis) to fetch the spec URLs for an API.

  ConnectorNo auth

• get_vessel_infoA

  Datalastic Vessel Tracking & Maritime IntelligenceA

  Return static specifications for a single vessel, identified by exactly one of: MMSI (9 digits), IMO (7 digits), or Datalastic UUID. Includes physical dimensions (length, breadth, draught), tonnage and cargo capacity (gross tonnage, deadweight, TEU, liquid gas), speed characteristics, year built, flag country, callsign and home port. This is reference data, NOT live position — use get_vessel for the current position, or find_vessels to search the registry by attributes.

  ConnectorNo auth

• oasdiff_breaking_changesA

  oasdiffA

  Detect breaking API changes between two OpenAPI specifications. Pass the base (old) and revision (new) specs as YAML or JSON; returns the breaking and warning-level changes. Use this when the question is whether an API change breaks existing clients. Use oasdiff_changelog instead to list every change including non-breaking and informational ones, oasdiff_diff for the raw added/removed/modified structure, or oasdiff_validate to check a single spec rather than compare two. Both specs must be valid, self-contained OpenAPI (external $ref URLs or files are not resolved).

  ConnectorNo auth

• delete_mcp_serverA

  AgentPlaybooksA

  Disconnect an MCP or OpenAPI server from this playbook. The remote server is not shut down; only this playbook's connection record is removed. Requires playbooks:write or full permission. Use update_mcp_server to change configuration without disconnecting. Pass playbook_id as the UUID or GUID of the playbook this call should target.

• agent_surface_budget_auditA

  x402-data-gatewayA

  Measure one public service's credential-free MCP tools/list, OpenAPI, or both declared discovery surfaces before any tool call or target payment. Use `agent_discoverability_audit` for catalog reach and rank, `seller_integrity_audit` for one exact operation's response contract, or this tool for byte budgets, heaviest definitions, missing selection contracts, and progressive-discovery fixes. Unselected surfaces are not fetched or judged. It follows no redirect, calls no target tool, sends no credential or target payment, and returns no target schema, response body, or session identifier.

• factreason_integration_briefA

  FactGrid (Renamed to FactReason)A

  Compile one callable third-party API brief: base URL, auth scheme, required parameters and types, request body, and documented response codes. Service is required and endpoint optionally narrows the operation. Set responseFormat="compact" for tokenizer-measured context savings; the backward-compatible default returns the full brief plus compact form. Uses metered access. Prefer factreason_api_schema when exploring multiple endpoints.

• exploreA

  ThinAir GeoA

  BROWSING / DISCOVERY search — cities, neighbourhoods, or mixed venues near a location. Use this when the user is exploring a REGION rather than looking for a specific category. Supports population filtering ('cities > 100k'), distance/population sorting, and layer filtering (locality / neighbourhood / venue / address / street). For specific POI categories (gas, food, charging, etc.), use `search_places` instead.

  ConnectorOAuth

• list_capabilitiesA

  Cito APIA

  Curated catalog of cito-mcp tools, games, jobs, and builder recipes. When to use: - Session start or "what can you do?" - Mapping app screens to tools - Filtering by game or job (live_board, match_page, team_page, player_form, standings, h2h, schedule, preview, event_card, app_scaffold) Prefer over: guessing from memory; exploring raw OpenAPI via call_api. Do not use when: you already know the tool and have IDs — call that tool directly. Parallel-safe: yes. Upstream cost: 0. Example: { "game": "cs2", "job": "live_board", "includeExamples": true }

• get_schema_definitionsA

  SpecProofA

  Look up formal, machine-checkable structure defined in the specifications: ASN.1 types (3GPP RRC/NAS message grammars) and JSON Schema / OpenAPI models (5G Service Based Interfaces). Prefer this over prose search when the question is about a message's *structure* — field names, types, ranges, optionality. The definition is returned verbatim from the spec, so it is exact rather than recalled. Args: name: Type or schema name, e.g. "RRCSetup", "MeasConfig", "SmContextCreateData" spec_number: Restrict to a spec, e.g. "38.331" kind: "asn1", "openapi" or "json_schema" limit: Maximum definitions to return (default: 10, max: 25)

• cc.strategy_data_parserA

  Central Command — x402 Trading IntelligenceA

  Call cc.strategy_data_parser — Parses natural language strategy descriptions into structured executable specifications: timeframes, indicators, patterns, risk parameters, and entry/exit rules. Purpose: Parses natural language strategy descriptions into structured executable specifications: timeframes, indicators, patterns, risk parameters, and entry/exit rules. Behavior: READ-ONLY. Does not place orders, move funds, or mutate your exchange account. Live / near-real-time data. Auth: X-Api-Key or x402 payment proof (X-PAYMENT / __x_payment). Anonymous unauthenticated calls receive HTTP 402 with payment accepts. Cost: $0.01 USDC per successful call (x402 Base USDC pay-per-use or prepaid X-Api-Key balance). Linked Connect keys are free. This is billing, not a side effect. Rate limit: 20/min (per API key). Tier: standard. Returns: Structured strategy object: TimeframeReq[], IndicatorReq[], PatternReq[], RiskParams, entry_conditions, exit_conditions — ready for backtesting or live execution. Guidelines: Compute / parse / backtest only — no live orders. Feed outputs into cc.agent_strategy with force_paper=true to paper-trade. Tags: parser, nlp, strategy, structured-data, automation.

• search_datasheetsA

  sheetsdata-mcpA

  Semantic search across all extracted datasheets. Finds components matching natural language queries about specifications, features, or capabilities. Best for broad spec-based discovery across all parts (e.g. 'low-noise LDO with PSRR above 70dB'). Only searches datasheets that have been previously extracted — not all parts that exist. For finding specific parts by number, use search_parts instead.
