  description: >-
    Public connections authorize end users via OAuth 2.0 authorization code flow.
    What a token can do is governed by integration "capabilities" (read/insert/update
    content, read/insert comments, read user info) rather than granular OAuth scopes.

  - flow: authorizationCode

notes:
  - The remote Notion MCP server (mcp.notion.com) requires user-based OAuth; discovery at /.well-known/oauth-authorization-server.
  - No granular OAuth scope surface — capabilities are configured per integration; scopes/ artifact intentionally omitted.
