Supports importing booking URLs from Calendly to create bookable SMB records.
Enables sending emails with full compliance checks.
Supports importing booking URLs from Square to create bookable SMB records.
Enables sending SMS and placing voice calls with full compliance checks (TCPA, GDPR, CASL).
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Agent Brokerfind a plumber in Brooklyn and schedule an appointment"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Agent Broker - SMB Transaction & Communication MCP Server
An agent-callable MCP server that lets autonomous AI agents find, verify, message, schedule with, and transact with small and mid-sized businesses (SMBs) through a single compliance-enforced tool surface.
Live endpoint: https://hatchloop.dev/mcp/agent-broker (streamable-http, always-on Cloudflare edge)
Why this exists
There are tens of millions of long-tail small businesses in the US - barbers, plumbers, accountants, home cleaners - and they have no API surface. AI agents that need to schedule a haircut, get a quote, or send a confirmation today must either drive a browser, cold-call by voice, or give up.
This server is the missing middle layer. Agents call us; we route to the right SMB through whichever channel reaches them fastest - Cal.com -> WhatsApp -> SMS -> voice AI -> email - with full TCPA / GDPR / CASL / 10DLC compliance enforced as a non-bypassable gate.

Verifiable compliance receipts
screen_sanctions and check_compliance attach a compliance receipt: a
hash-bound record of which list copies were screened (and how fresh they were),
which ruleset decided, what inputs it was given, and what it returned. It is
signed with Ed25519 and verifiable offline - months later, with no call
back to us. It asserts facts about our system's actions only; it never claims
"this party is clean."
Verify one in ~12 lines (pin the public key from hatchloop.dev/agents.md):
import json, hashlib
from cryptography.hazmat.primitives.asymmetric.ed25519 import Ed25519PublicKey
PINNED_KEY_HEX = "<hex public key from hatchloop.dev/agents.md>"
receipt = json.load(open("receipt.json")) # the compliance_receipt object
payload, integrity = receipt["payload"], receipt["integrity"]
canonical = json.dumps(payload, sort_keys=True, separators=(",", ":"),
ensure_ascii=True, allow_nan=False).encode()
assert integrity["payload_sha256"] == "sha256:" + hashlib.sha256(canonical).hexdigest()
Ed25519PublicKey.from_public_bytes(bytes.fromhex(PINNED_KEY_HEX)).verify(
bytes.fromhex(integrity["signature"]), canonical) # raises if tamperedIf no signing key is configured on the server, the receipt says
signature_status: "unsigned" with the reason - it never claims a signature it
does not have.
Quick start
Connect via MCP (Claude Desktop, Cursor, Cline, Continue, etc.)
{
"mcpServers": {
"agent-broker": {
"url": "https://hatchloop.dev/mcp/agent-broker"
}
}
}15 tools require no key. 12 are always free (find_business, verify_business, check_booking_link, check_compliance, get_conversation, get_status, get_outcome, preview_cost, self_test, check_quota, mint_key, lookup_us_contracts) and 3 more are free within a daily quota (verify_company_record, screen_sanctions, map_trade_restriction).
Write tools require an X-Agent-Identity bearer token:
Free email-verified key (100 ops/day): https://hatchloop.dev/agent-broker
Machine-mintable key (no email, agent self-serve):
POST https://api.hatchloop.dev/keys/mint- see Machine-mintable keys below.Credits from $9/1,000 ops: https://hatchloop.dev/pricing
Add your key to the config once you have one:

"url": "https://hatchloop.dev/mcp/agent-broker",
"headers": {
"X-Agent-Identity": "Bearer YOUR_KEY_HERE"

AI agents that cannot receive email can self-provision a free-tier API key (100 gated ops/day) by proving identity via HMAC-SHA256.
How it works
Obtain the
MACHINE_MINT_SECRETfrom hatchloop.dev/docs/#machine-mint.Compute the signature:
signature = HMAC-SHA256(agent_id + str(timestamp) + nonce, MACHINE_MINT_SECRET)The HMAC input is the raw concatenation of the three fields (no separators). Digest must be lowercase hex.
POST to
https://api.hatchloop.dev/keys/mint:
{
"agent_id": "my-agent-abc123",
"timestamp": 1725100000,
"nonce": "4f8a2c1d9e2b7c6a",
"signature": "<lowercase-hex-hmac>"
}Response
{
"ok": true,
"key": "<JWT - use as X-Agent-Identity header>",
"key_id": "free_machine_<hash>",
"expires_at": "2026-11-28",
"tier": "free",
"daily_limit": 100,
"usage": "Send as the X-Agent-Identity header on every call to https://hatchloop.dev/mcp/agent-broker"
}Constraints
timestampmust be within 60 seconds of server time (prevents replay attacks).Use a fresh
nonceon every call (UUID or random hex).agent_idis a stable identifier for your agent; the issued key is tied to its SHA-256 hash.Returns
401 {error: "invalid_request"}on bad signature or stale timestamp.Returns
503 {error: "not_configured"}if the server secret has not been set (contact hello@hatchloop.dev).

Idempotency is keyed by (agent_id, operation, idempotency_key) with 24h TTL. Async operations return pending_async; poll with get_status / get_outcome.
Compliance
Every outbound communication passes through compliance/pre_check():
Content classification - blocks restricted categories (gambling, adult, cannabis, spam)
Opt-out check - TCPA STOP keyword, GDPR right-to-be-forgotten, CASL
Consent check - TCPA written consent, GDPR opt-in, CASL implied/express
10DLC registry check - US SMS campaign compliance
Two-party recording consent - CA, FL, IL, MD, MA, MT, NV, NH, PA, WA
Audit log - PII stored as SHA-256 hash, never plaintext
Violations surface as ComplianceViolationError and are never silently bypassed.
