description: >-
  OAuth 2.0 scopes for Alpaca Connect (third-party apps acting for Alpaca users on the Trading and
  Market Data APIs). Read-only endpoint access is assumed by default when no scope is requested.
  The harvested OpenAPI declares only apiKey/basic schemes, so this scope surface comes from the
  published OAuth docs, plus the RFC 8414 metadata of the authx authorization server that fronts
  the hosted Broker MCP Server.
schemes:
  - name: Alpaca Connect OAuth 2.0
    flows:

        notes:
          - Optional env parameter (live | paper); both prompted if unspecified.
          - scope is a space-delimited list; read-only access is the default grant.
