  No OpenAPI in this repo declares an oauth2 securityScheme, so derive-oauth-scopes.py found
  nothing (0 providers with oauth2). These scopes are real all the same: they are published in
  Dremio's OAuth Token documentation and advertised in the live RFC 8414 discovery document the
  hosted MCP server serves. The scope surface is deliberately coarse.
schemes:
- name: DremioOAuth
  type: oauth2

  flows:
  - flow: clientCredentials

    note: For service users, using client_id + client_secret. Token lifetime one hour.

  - flow: tokenExchange

    grant_type: urn:ietf:params:oauth:grant-type:token-exchange
    note: >-
      Exchange an external OIDC JWT (subject_token_type urn:ietf:params:oauth:token-type:jwt)
      or a personal access token for a Dremio access token.
scopes:
- scope: dremio.all
  description: >-
    Full access to Dremio resources. Dremio's documentation states the scope "must be set to
    dremio.all" for the client-credentials flow and that a token exchange returns dremio.all.
  flows: [clientCredentials, authorizationCode, tokenExchange]

  description: Issues a refresh_token alongside the access token so a client can renew without re-consent.

granularity:
  level: coarse
  assessment: >-
    There is exactly one access scope and it is all-or-nothing. An agent cannot be issued a
    read-only Dremio token through OAuth; least privilege has to be expressed through Dremio's
    own RBAC (roles, grants, row-access and column-masking policies) on the user or service user
    the token represents, not through the token's scope. For an agent deployment that is the
    load-bearing fact: scope the service user, because the scope string will not scope anything.
