description: >-
  Syncari operates two OAuth 2.0 surfaces but publishes no scope vocabulary for either. This artifact records that
  measured absence rather than inventing one. The MCP protected-resource metadata is served anonymously and its
  scopes_supported array is empty; the Embed REST API documents the client-credentials flow with no scope parameter
  at all, and authorises instead by the role and instance assigned to the API user.

    RFC 8414 metadata declares grant_types authorization_code and refresh_token with PKCE S256 and dynamic client
    registration, but carries no scopes_supported key.

    The documented token request is grant_type=client_credentials with client_id and client_secret only. No scope
    parameter is documented and no scope appears in the sample token response.

  note: >-
    Access is decided when the API user is created in Settings > Users, not per token. The Role API (June 2026)
    lets an Org Admin manage custom roles and assign them to users programmatically, which is the closest thing
    Syncari has to a machine-readable permission surface.
consent_surface_exists: true
consent_evidence: >-
  Syncari's Claude connector walkthrough shows a "Syncari MCP Authorization Request screen ... listing the
  permissions being requested" before the user clicks Accept, so permissions are named to the human but not
  published to machines.
gap: >-
  A published scopes_supported list on the MCP protected-resource metadata, and a documented scope reference page,
  would let an agent reason about least privilege before it connects. Today it cannot.
