notes: >-
  The Composio platform API is API-key authenticated (project, user, and org keys via
  header, plus a cookie session for the dashboard). API keys can carry scoped
  permissions (e.g. MCP, files, realtime routes). Distinct from this, Composio manages
  OAuth2 flows on behalf of end users to connect third-party toolkits (delegated auth);
  those tokens are held by Composio and never exposed to the agent, so they are not a
  securityScheme on this API.
