    description: >-
      SegmentStream's MCP server is a public OAuth 2.0 client using the
      authorization-code flow with PKCE (S256) and RFC 7591 dynamic client
      registration. Sign-in happens in the browser and grants the agent the
      same permissions as the signed-in SegmentStream user (read-only reporting
      by default). Discoverable via RFC 8414 / RFC 9728 metadata.
    flows:
      - flow: authorizationCode
        authorizationUrl: https://mcp.segmentstream.com/oauth/authorize
        tokenUrl: https://mcp.segmentstream.com/oauth/token

notes: >-
  No public REST OpenAPI is published (docs reference an openapi.json that
  currently 404s), so this profile is derived from the OAuth discovery metadata
  the MCP server publishes rather than from an OpenAPI securitySchemes block.
