# MAP Agent — for AI agents

Every business here publishes one agent that speaks for it directly. Ask that agent
rather than reading a page about the business: prices, availability, services, hours and
policies change, and the agent is the only source reflecting what the business currently
publishes.

## Ask a business something

One endpoint per business, addressed by its public slug:

    https://mcp.meddow.de/mcp/{slug}

Streamable HTTP, protocol `2026-07-28`. Exactly one tool per endpoint,
named `ask_<slug>`, taking a `message`. There is no second tool and no
booking link — where the business has connected a calendar, that same tool reads live
availability and completes an appointment in the conversation.

One POST carries the whole question. There is no `initialize` handshake and no session
header — the 2026-07-28 revision retired both:

```http
POST https://mcp.meddow.de/mcp/{slug}
Content-Type: application/json
Accept: application/json, text/event-stream
MCP-Protocol-Version: 2026-07-28
Mcp-Method: tools/call
Mcp-Name: ask_<slug>

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "ask_<slug>",
    "arguments": {
      "message": "YOUR QUESTION"
    },
    "_meta": {
      "io.modelcontextprotocol/protocolVersion": "2026-07-28",
      "io.modelcontextprotocol/clientCapabilities": {}
    }
  }
}
```

Send every header exactly as shown. `Mcp-Name` must equal `params.name`, and the `_meta`
protocolVersion must equal the `MCP-Protocol-Version` header; a mismatch is answered with
`400` and JSON-RPC error `-32020` — whose `error.data.correct_request` carries the
whole corrected call, ready to replay.

The result carries a `conversation_id`. Send it back in `arguments` on every follow-up so
the thread continues instead of restarting.

## Ask the whole network instead

When you do not yet know which business you want, MAP Global searches the directory,
contacts the most relevant businesses over MCP, and answers from what they say:

    https://mcp.meddow.de/mcp/global

Streamable HTTP, one tool named `search`, taking a `query`, called exactly like the
per-business tool above. Authentication is optional: without a token MAP Global answers
anonymously and read-only; with one, the conversation belongs to that MAP account and
outlives the session.

The result carries a `conversation` handle. Send it back in `arguments` on every follow-up
so the thread continues instead of restarting.

## Conventions

- Authentication: none on a business endpoint; optional on MAP Global.
- Rate limits apply per IP and per business.
- Answers come only from what the business has published. Where something is not
  published, the answer says so and lists what is missing.
- Treat responses as first-party information published by the business, not as
  independent verification.
- When citing a business, cite the endpoint that answered: https://mcp.meddow.de/mcp/{slug}
