Backstage OAuth Scopes

OAuth 2.0 probed

Backstage publishes 1 OAuth 2.0 scope. Scopes are the fine-grained permissions an application requests at authorization time to act against the Backstage API on a user’s behalf.

This index is generated from the provider’s OpenAPI security definitions (and, where available, its documented scope reference) and refreshes on every APIs.io network build. Browse every provider’s scopes at scopes.apis.io.

description: >-
  Backstage's first-party plugin OpenAPIs declare a bearer `JWT` scheme with no oauth2 flows and no
  scopes, so there is no scope surface on the REST APIs. A real OAuth scope surface does exist on
  the MCP Actions endpoint: the protected-resource and authorization-server metadata documents
  served by a running Backstage backend advertise a single scope. Authorization inside Backstage is
  not scope-based — it is the Permissions framework, which evaluates named permissions
  (e.g. catalog.entity.read) through a policy, and that is a different mechanism from OAuth scopes.

authorization_model_note: >-
  Fine-grained access is enforced by the Backstage Permissions framework rather than OAuth scopes.
  See https://backstage.io/docs/permissions/overview — permissions are named
  (<plugin>.<resource>.<action>) and resolved by a policy that can attach conditional rules.
