  • Org name: Doxy.me

  • Details:
    We’re integrating with Deel’s MCP server (https://api.letsdeel.com/mcp) via OAuth.
    Discovery, dynamic client registration, and user authorization all succeed. The failure happens only at the token exchange step:
    Request: POST https://api.letsdeel.com/oauth/tokens
    Auth: public client (token_endpoint_auth_method: none) with PKCE
    Response: 401 unauthorized_client
    Error message:

    index row size 2856 exceeds btree version 4 maximum 2704
for index "oauth_access_tokens_token_key"
