description: >-
  The complete scope set SiFive Cloud Services advertises in its RFC 8414 metadata. SiFive
  publishes no scopes/permissions reference page, so these three values are the only
  authoritative statement of the SCS OAuth permission surface that exists publicly. The
  two mcp:* scopes are the provider's own evidence of a Model Context Protocol resource
  server behind the portal — see mcp/sifive-mcp.yml.

    Read access to the Model Context Protocol resource server behind SiFive Cloud
    Services. Description is inferred from the scope name and MCP convention — SiFive
    publishes no scope reference page. The resource endpoint itself was not publicly
    discoverable.

gaps:
- >-
  No published scopes/permissions reference. The names above are the entire public record;
  the two mcp:* descriptions are inferred from the scope name, not quoted from SiFive.
- >-
  No RFC 9728 protected-resource metadata is served, so the resource server(s) these
  scopes protect cannot be discovered from the authorization server.
