description: >-
  Blueshift declares eight OAuth 2.0 scopes, published in machine-readable form
  in both its RFC 8414 authorization-server metadata and its RFC 9728
  protected-resource metadata, on all four API/app hosts (US and EU). They apply
  to the MCP server, not the REST API — the REST API has no OAuth at all. The
  scope set is a clean read/write pair over four domains, which is materially
  better granularity than the two all-or-nothing API keys the REST API offers.
  Descriptions below are derived from the scope names and the corresponding MCP
  tool categories; Blueshift publishes the scope strings but no scope reference
  page, so no description here is quoted from Blueshift.

not_applicable_to: >-
  Blueshift REST API — authenticates with HTTP Basic and an API key, and
  declares no oauth2 securityScheme in its OpenAPI.

observations:
  - >-
    The scope set does NOT cover every MCP tool category. Reporting and
    dashboards, schema discovery, recommendations, the AI campaign optimizer,
    pages and scripts, image management and marketing insights all appear in
    Blueshift's published tool catalogue with no corresponding scope, so either
    those tools fall under an existing scope by association or the scope model
    has not caught up with the tool surface. Blueshift publishes nothing that
    resolves this, and it is not inferred here.
  - >-
    Dynamic client registration is open (registration_endpoint present,
    token_endpoint_auth_methods includes "none"), which is what lets an MCP
    client connect with only a URL.
  - >-
    The same eight scopes are served identically from api.getblueshift.com,
    api.eu.getblueshift.com, app.getblueshift.com and app.eu.getblueshift.com.
