Ripgrep MCP Server

An MCP server that provides ripgrep (rg) search capabilities to any MCP client such as Claude.

Overview

This server provides a Model Context Protocol (MCP) interface for the powerful ripgrep search tool. It enables Claude AI and other MCP-compatible clients to perform high-performance text searches across files on your system.

Prerequisites

• Node.js (v18 or higher)

• ripgrep (rg) command installed and available in your PATH. Install it with brew install ripgrep on macOS.

Usage with Claude for Desktop

To use this MCP server with Claude for Desktop:

1. Edit your Claude for Desktop configuration file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add the following to your configuration:

   {
     "mcpServers": {
       "ripgrep": {
         "command": "npx",
         "args": ["-y", "ripgrep-mcp@latest"]
       }
     }
   }

   Replace /path/to/ripgrep-mcp with the absolute path to where you cloned this repository.

3. Restart Claude for Desktop.

Security Considerations

This MCP server executes the ripgrep binary on your machine. It passes arguments directly to rg without shell command string construction, but you should still use caution when providing paths and patterns because searches run against your local filesystem.
