  note: >-
    The REST API (api.entergram.com) authenticates with a workspace-scoped X-API-Key header. The
    hosted MCP server (mcp.entergram.com) authenticates with OAuth2 authorization_code + PKCE against
    app.entergram.com, with dynamic client registration. The OAuth profile was captured by probing
    the RFC 8414 / RFC 9728 discovery documents, not from the REST OpenAPI (which declares apiKey only).
