note: >-
  The OpenAPI declares no oauth2 securityScheme (derive-oauth-scopes.py correctly found nothing); OAuth 2.1 access
  tokens are accepted by the REST API through the bearer_auth http scheme ("Send the same API key, or an OAuth 2.0
  access token, as a Bearer token") and by the MCP server. The scope vocabulary therefore comes from the RFC 8414 /
  RFC 9728 metadata and auth.md, all provider-published and fetched live on 2026-09-19 and re-verified 2026-10-03,
  when the issuer had moved from https://api.spacefrontiers.org to https://api.machinelibrary.ai.

  mcp_tools_note: The MCP server's only scope covers all nine machinelibrary_* tools (legacy spacefrontiers_* aliases accepted). Per docs/api/operations (2026-10-03), approval lets the application search and retrieve using account credits, and publish AI-labeled comments and votes on the user's behalf.
  note: The only scope offered; auth.md instructs clients to "request only search". Payment tools/endpoints are not covered by a distinct scope in the published metadata.
