Peacock MCP Server provides a lightweight MCP endpoint you can connect to from MCP clients to interact with the Peacock extension APIs. It enables you to query Peacock documentation, fetch extension-related data, and test tool-based workﬂows from your preferred MCP client. This server is designed to be simple to run locally or integrate into your existing MCP tooling.

How to use

To use the Peacock MCP Server, connect an MCP client to the local server and start sending tool queries. You can discover the server via MCP discovery features in supported clients or specify the server connection directly using the standardized MCP entry. A practical workflow is to fetch Peacock documentation through the server’s dedicated tool, which exposes Peacock extension information and usage guidance.

How to install

Prerequisites: you need Node.js and npm installed on your system. Verify with node -v and npm -v in your terminal.

Install and run the Peacock MCP Server using the standard MCP entry that uses npx to launch the package.

Option 1: Install via Smithery (automatic install for Claude Desktop):

npx -y @smithery/cli install @johnpapa/peacock-mcp --client claude

Configuration and usage notes

Associate the MCP server with a specific repository by creating a VS Code MCP configuration. This enables the server to be available for that repository’s tooling.
