MCP docs finally list Cargo as a registry package type that has been live in production for weeks
GitHub·low signal
PR #3315, merged 2026-08-30, documents `registryType: "cargo"` on the MCP registry package-types page. The registry has supported Cargo since registry PR #1207 and it has been live in production the whole time, but the docs page never listed it, so Rust MCP server authors had no documented path to publish. Worth knowing if you have been shipping Rust servers via npm or PyPI wrappers.
