description: The quote, ticket and part operations as Model Context Protocol tools for AI agents.
---

The same operations for quotes, tickets and parts are available as 9 [Model Context Protocol](https://modelcontextprotocol.io) tools at a single endpoint:

```bash
https://next.amfg.ai/engine-service/public-api/v1/mcp
```

It speaks JSON-RPC 2.0 over Streamable HTTP, spec revision `2026-07-28`, and still serves 2025-era clients. It uses the same `Authorization` header as the REST API.

## Connect Claude Code

```bash
claude mcp add --transport http amfg "https://next.amfg.ai/engine-service/public-api/v1/mcp" \
  --header "Authorization: <secret>"
```

## Protocol notes

- For `2026-07-28` requests, send `MCP-Protocol-Version: 2026-07-28` to match `params._meta["io.modelcontextprotocol/protocolVersion"]`.
- `tools/list` returns the 9 tools, and `tools/call` invokes one.
- A failed operation, such as a validation error or a missing entity, returns a **result** with `isError: true` and the original error message. JSON-RPC errors are only for malformed or unknown calls.
- Tool input schemas are published in the [API reference](/engine-service/public-api/v1/docs/reference) under the MCP operation.
