Context

The official MCP Registry at registry.modelcontextprotocol.io is the canonical discoverability mechanism for MCP servers. The old modelcontextprotocol/servers README list is retired; new servers publish via mcp-publisher CLI.

Challenge

The official registry quickstart targets npm/PyPI packages. Patchloom is a Rust binary distributed via crates.io, Homebrew, and GitHub Releases. We need to determine the correct registryType and packages configuration for a Rust/cargo binary.

Steps

1. Install the mcp-publisher CLI
2. Run mcp-publisher init to generate server.json
3. Configure server.json:
   • name: io.github.patchloom/patchloom
   • description: match crates.io description
   • repository: https://github.com/patchloom/patchloom
   • packages: determine correct registryType for crates.io or GitHub Releases
   • transport: stdio
   • environmentVariables: none required
4. Authenticate: mcp-publisher login github
5. Publish: mcp-publisher publish
6. Verify the listing appears at registry.modelcontextprotocol.io
7. (Optional) Automate publishing in CI via GitHub Actions
