mcp -cat-api

This MCP server is an experimental implementation of a Cat API. It currently implements the search breeds route, allowing clients to query cat breeds from a provider or dataset built into the server. To start the server, use the Rust toolchain to compile and run in release mode. Once running, you can interact with the MCP inspector from Node.js to explore the protocol messages exchanged with the server. The inspector is invoked with the command shown in the README: npx @modelcontextprotocol/inspector. This lets you observe requests, responses, and the structure of MCP frames as you integrate or test tooling against the server.

To use the server's capabilities, issue requests targeting the search breeds route to retrieve breed information (such as name, origin, coat, and temperament) and related metadata. The server is designed to be inspected and tested with the MCP inspector, which helps you validate message formatting and protocol adherence while developing integrations.

Prerequisites:

• Rust toolchain installed (Rustup, cargo)
• Basic familiarity with building Rust projects

Installation and run steps:

1. Ensure Rust is installed. If not, install via rustup: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh source $HOME/.cargo/env

2. Clone the MCP server repository (or navigate to the project directory).

3. Build and run in release mode: cargo run --release

4. Once the server starts, you should see it listening for MCP connections. To inspect MCP traffic, use the Node inspector: npx @modelcontextprotocol/inspector

Notes:

• The server is currently focused on the search breeds route. Additional routes may be added in future updates.
• If you need to adjust runtime behavior or environment variables, edit the server configuration or code accordingly and re-run cargo run --release.

Tips and caveats:

• The server is experimental and may not implement all routes of the Cat API; currently, only the search breeds route is noted as implemented.
• Use the MCP inspector (npx @modelcontextprotocol/inspector) to observe protocol messages for debugging and integration testing.
• If you plan to run in a container, consider building a small image that runs cargo run --release and exposes the appropriate port. The README does not specify defaults for port or environment variables, so you may need to confirm runtime details from the code or log output.
• Check for updates to the inspector tool to ensure compatibility with the MCP protocol version used by this server.
