# End an MCP session (streamable-HTTP transport)

`DELETE /mcp`

## Request

- Base URL: `https://api.infolang.ai`
- URL: `https://api.infolang.ai/mcp`
- Auth: one of:
  - HTTP bearer
  - HTTP bearer

Proxied verbatim to Kairos. The gateway applies NO authentication of its own here — /v1 and /mcp sit outside the /v2 middleware, so the Authorization header is forwarded untouched and Kairos is the sole authority. In practice that means either `il_*` credential is accepted (an API key, or an `il_oauth_` token — the latter is how an MCP client reaches /mcp); a Supabase session JWT is NOT, since Kairos cannot verify one. Response shapes are owned by Kairos. The gateway forwards ALL methods under /v1/* and /mcp — the operations listed here are the primary surface, not an exhaustive proxy inventory.

## Response `200`

Session ended, if supported upstream
