Implements the server-side portion of SEP-2207 for the MCP Spec 2026-07-28 release.

Tracked by umbrella #338.

Spec summary

MCP servers (as resource servers) SHOULD NOT advertise/require offline_access in their PRM (Protected Resource Metadata) responses — it's an AS concern, not RS.

PHP SDK changes

  • Audit PRM emission in src/Server/Transport/Http/OAuth/ to ensure offline_access is NOT included in the server's scopes_supported or required-scope advertisements.
  • Likely a small check/lint plus a unit test guarding against regression.
