+## Plan

+Review dispatch:
+- Spawned Reviewer Pod `yoi-reviewer-00001KVHR3WS6-r1` against implementation branch `impl/00001KVHR3WS6-mcp-tool-registration`。
+- Review target commit: `66fa9d55 mcp: register stdio server tools`。
+- Review baseline: `a59e5c1e`。
+- Reviewer task focuses on normal ToolRegistry contribution path, untrusted metadata/schema/name normalization, no `tools/call`, discovery-only invocation behavior, no resources/prompts/list_changed registration, diagnostics bounds, secret-store deferral, and tests。
+- Reviewer is instructed not to edit source, commit, merge, close the Ticket, or use TicketReview directly; it will report verdict/evidence back to Orchestrator。
