# MCP OAuth callback

`GET /mcp/oauth/callback`

Server-hosted OAuth redirect target. The authorization server redirects the user's browser here with ?code & ?state; this completes the matching in-flight flow (validated by the unguessable state) and renders a success/failure page. Reachable from web + mobile, unlike the 127.0.0.1 loopback callback.

## Query parameters

- `directory` string
- `workspace` string

## Response `200`

Authorization handled (success or provider error)

## Other responses

- `400` — Missing or invalid state / code
