cat

The Cat MCP Server is a lightweight MCP server designed to be easily integrated with desktop automation tools and environments through a simple npx-based invocation. Once running, it exposes an MCP-compatible interface that other applications can connect to in order to leverage the cat-focused moderation and management capabilities offered by this server. This setup is particularly convenient for users who want a plug-and-play MCP backend without managing a full deployment, as it can be launched on-demand via npx and consumed by compatible clients like desktop apps, IDEs, or automation scripts. To connect, configure your MCP consumer with the provided server name and the command sequence shown in the setup snippet, and your client will be able to interact with the server as if it were a locally hosted MCP instance.

Prerequisites:

• Node.js (LTS version) and npm installed on your system
• Access to the internet to fetch the npm package via npx

Step-by-step installation:

1. Verify prerequisites:

   • node -v
   • npm -v

2. Run the MCP server via npx (no permanent install required): On macOS/Linux:

   npx -y cat-mcp-server

   On Windows (PowerShell):

   cmd /c npx -y cat-mcp-server

3. If you want to ensure the server is always available, you can install the npm package globally and then run it via the cached binary: npm i -g cat-mcp-server cat-mcp-server

4. Alternatively, use the exact configuration example in your MCP client configuration to start the server as part of your system’s startup routine.

5. Verify installation by connecting a client that uses the MCP protocol and observing a successful handshake.

Notes:

• The recommended usage is via npx for a no-install approach, but you can install globally if you prefer a persistent binary.
• If you encounter networking issues, ensure your firewall allows localhost connections used by MCP clients.
• There are no mandatory environment variables shown in the README; placeholders can be added to a local environment file if needed for integration, such as MCP client-specific URL or authentication tokens, depending on your setup.
• The server name in the MCP config is cat-mcp-server; adjust if you alias it differently in your environment.
• For Windows users, the wrapper example uses a cmd invocation to run npx with the same arguments.
