The MCP SDK reconverts every registered Zod schema on each tools/list. With 139 tools that is ~45 ms of Zod JSON Schema work per listing, for a catalog that cannot change after registration. Memoize the advertised input and output projections per target on the registration clones. Listings are byte-identical; repeated tools/list drops from ~62 ms to ~18 ms on the stdio server.
