Grafana Loki OAuth Scopes

OAuth 2.0 probed

Grafana Loki uses OAuth 2.0 but publishes no discrete scopes — access is governed by the grant itself (e.g. client-credentials or role-based authorization) rather than per-scope consent.

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.

  Grafana Loki itself has no OAuth surface. Two scope vocabularies govern access to Loki data: the
  OAuth 2.1 scopes published by the hosted Grafana Cloud MCP server (read anonymously from its
  RFC 8414 authorization-server metadata), and the Grafana Cloud / Grafana Enterprise Logs access
  policy scopes named in the Loki HTTP API reference for the logs surface.
