About MCP Ripgrep Server

MCP Ripgrep Server is an MCP server that wraps the ripgrep (rg) search tool so that clients such as Claude can search text across local files. It is intended for users who want an AI assistant to look up code or file contents.

Key features

  1. 01Text search through ripgrep
  2. 02Fixed-string and file-type filtering
  3. 03Match counting
  4. 04Listing files that would be searched

Use cases

  1. 01Letting an AI assistant search a source directory for a pattern
  2. 02Counting occurrences of markers such as TODO in a codebase
  3. 03Checking which files of a given type would be searched

MCP support

This project is an MCP server that exposes the search, advanced-search, count-matches, list-files and list-file-types tools to MCP clients.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "ripgrep": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-ripgrep"
      ]
    }
  }
}
Run commandnpx -y mcp-ripgrep

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

MCP Ripgrep 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", "mcp-ripgrep@latest"]
    }
  }
}

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

  3. Restart Claude for Desktop.

Available Tools

search

Basic search with ripgrep:

Pattern: error
Path: ./src
advanced-search

More advanced search with additional options:

Pattern: function
Path: ./src
FixedStrings: true
FileType: ts
IncludeHidden: false
count-matches

Count occurrences of a pattern:

Path: ./src
FileType: js
list-file-types

List all supported file types in ripgrep.

Security Considerations

This MCP server executes shell commands using the ripgrep tool. While efforts have been made to safely escape arguments, use caution when providing input as it runs commands on your machine.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
