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.

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://agent-broker-edge.basil-agent.workers.dev/mcp (streamable-http, always-on Cloudflare edge)
Why this exists
There are ~60 million 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 → SMS → voice AI → email — with full TCPA / GDPR / CASL / 10DLC compliance enforced as a non-bypassable gate.

Per-call payments via x402/USDC on Base | Coming soon — not yet active — tools are currently free |
Production SMB onboarding | Planned — real businesses not yet enrolled |
The MCP server is live and callable right now. Bookings hit demo data, and per-call payments (x402/USDC) are not yet charged. Both are in progress.
14 MCP Tools
All tools are callable via MCP, REST, OpenAI function calling, Anthropic tool_use, or A2A protocol.

+-- Channel adapters (channels/ -- Twilio, Cal.com, Vapi, SendGrid)
+-- Billing + outcome store
+-- All .well-known / MCP endpoints (also served from edge bundle)The edge worker can outlive the origin: discovery still works even if the origin is down. 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.
