## MCP Integration — removed (2026-07-28)

The `/mcp` endpoint and the `api/app/mcp/` package no longer exist. Agents should use
the REST endpoints documented above, authenticating with `X-API-Key` or a Bearer JWT.

It was removed for three reasons: nobody was using it; its transport had been broken
for some time (it constructed a `StreamableHTTPServerTransport` per request with no
session handling, returning 500 even with valid credentials); and its unpinned SDK
took the entire API down in production when `mcp` released 2.0.0 and dropped
`Server.list_tools()`.

To bring it back: `git show edb500f5:api/app/mcp/server.py`. Pin the SDK to the 1.x
series and fix the transport before mounting it again.
