  Not derived from an OpenAPI — OneScreen publishes no REST contract. These scopes are read
  verbatim from the two anonymous OAuth discovery documents the MCP host serves: the RFC 8414
  authorization-server metadata (22 scopes) and the RFC 9728 protected-resource metadata for
  https://mcp.onescreen.ai/mcp (18 scopes). Descriptions are ours, inferred from the scope
  name and the provider's published product description; the scope STRINGS are the provider's.

scope_count: 22

naming:
  pattern: 'mcp::<resource>[.<sub-resource>]:<action>'
  actions:
  - read
  - write
  - send
  - connect
  note: >-
    Two generations of naming coexist in the authorization-server metadata. The current form
    puts the action last (mcp::inventories.pricing:read); four legacy scopes put it first
    (mcp::read:pricing). The legacy four are absent from the protected-resource metadata,
    which is the narrower and more current of the two documents.
