Partner Booking MCP Server (demo external agent)

A tiny, self-contained external MCP server that simulates a third-party vendor's appointment-booking agent. Point your platform's agent at its public URL to demonstrate real-time agent-to-agent interoperability — your agent orchestrating and exchanging tasks/context with an AI capability that is not hosted on your platform.

Transport: Streamable HTTP (stateless), so it deploys to any Node host and is reachable as a normal HTTPS endpoint.

Tools exposed

Services seeded: haircut, dental-checkup, car-service, consultation. Dates seeded: 2026-07-27, 2026-07-28, 2026-07-29. (In-memory — resets on restart.)

Run locally

npm install
npm start          # -> http://localhost:3000/mcp

Quick smoke test:

curl -X POST http://localhost:3000/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Deploy to a public URL

Render (easiest — render.yaml included):

1. Push this folder to a GitHub repo.

2. Render → New → Blueprint → pick the repo. It reads render.yaml.

3. You get a URL like https://partner-booking-mcp.onrender.com. Your MCP endpoint is https://.../mcp.

Railway / Fly / Cloud Run: same idea — Node app, start command node server.js, expose $PORT. A Dockerfile is included if the host prefers containers.

Free Render instances sleep when idle. Hit the URL once ~30s before the demo to wake it.

Connect it to your platform (the demo moment)

Register it as a remote MCP server in whatever your platform uses:

• Endpoint / URL: https://<your-host>/mcp

• Transport: Streamable HTTP

• Auth: none (demo). Add a bearer-token check in server.js if your platform requires one.

To try it in a generic MCP client, the connection config looks like:

{
  "mcpServers": {
    "partner-booking": {
      "type": "http",
      "url": "https://<your-host>/mcp"
    }
  }
}

Suggested demo script

1. User asks your platform's agent: "Book me a haircut next Monday morning."

2. Your agent calls check_availability on this external server → shows the slots.

3. Your agent calls book_appointment → returns confirmation BK-XXXXXXXX.

4. Emphasise: the booking logic + data live in a separate, third-party service — your platform discovered its tools and orchestrated the task live over MCP.

5. Optional: cancel_appointment to show a two-way, stateful exchange.

Notes for a production-shaped story

• Add auth (bearer/OAuth) at the /mcp route.

• Swap the in-memory store for a real DB/booking API.

• Same pattern maps to any partner capability — this is intentionally minimal so the interoperability is the star, not the business logic.
