# Authorize

`GET /api/v1/oauth/authorize`

Start OAuth flow: redirect user to Google login.

ChatGPT sends:
  GET /oauth/authorize?client_id=bolsai&redirect_uri=https://chat.openai.com/...&state=xyz&response_type=code

MCP clients additionally send PKCE (code_challenge + S256) and an RFC 8707
`resource` naming the MCP endpoint. We store them with the redirect_uri + state
in session, then send the user to Google.
