What’s Changed

The lookup tools now attribute the calling agent — and the release pipeline publishes the MCP-registry listing automatically.

  • Client identity on lookups (#91): check_server, list_servers, and request_grade send the connected client’s handshake identity (name/version plus declared title, website, description, and capability keys such as sampling/roots) to polygraph.so’s aggregate per-agent usage counters. Software metadata only — nothing about the user is read or sent; all fields are optional server-side.
  • Official MCP Registry auto-publish (#93): pushing a litmus-v* tag now also publishes server.json to registry.modelcontextprotocol.io via GitHub OIDC, with a fail-fast version-drift check.
  • polygraph plugin 0.6.0: spawn pinned to this release (#92).

No grading-semantics changes: litmus-v12 / litmus-skill-v2 unchanged.
