RepoMix MCP server

This MCP server allows you to pack your codebase into AI-friendly formats, making it easier to analyze code with large language models. The server provides tools for AI assistants to interact directly with your code repositories.

Installation

You can run the MCP server directly without installation using npx:

npx repomix --mcp

For repeated use, install globally:

# Using npm
npm install -g repomix

# Using yarn
yarn global add repomix

# Using Homebrew (macOS/Linux)
brew install repomix

Using with AI Assistants

Setting Up MCP Integration

Configure your AI assistant to use Repomix as an MCP server:

For Cline (VS Code extension)

Edit the cline_mcp_settings.json file:

{
  "mcpServers": {
    "repomix": {
      "command": "npx",
      "args": [
        "-y",
        "repomix",
        "--mcp"
      ]
    }
  }
}

For Claude Desktop

Edit the claude_desktop_config.json file with similar configuration.

Available MCP Tools

The MCP server provides four main tools:

1. Pack Local Codebase

Packages a local directory into a consolidated file for AI analysis.

Parameters:

• directory: Absolute path to the directory to pack
• compress: (Optional, default: true) Whether to perform intelligent code extraction
• includePatterns: (Optional) Comma-separated list of include patterns
• ignorePatterns: (Optional) Comma-separated list of ignore patterns

2. Pack Remote Repository

Fetches, clones and packages a GitHub repository.

Parameters:

• remote: GitHub repository URL or user/repo format (e.g., yamadashy/repomix)
• compress: (Optional, default: true) Whether to perform intelligent code extraction
• includePatterns: (Optional) Comma-separated list of include patterns
• ignorePatterns: (Optional) Comma-separated list of ignore patterns

3. Read File

Reads a file using an absolute path with security validation.

Parameters:

• path: Absolute path to the file to read

4. Read Directory

Lists contents of a directory using an absolute path.

Parameters:

• path: Absolute path to the directory to list

Output Options

When running as a standalone tool (not as MCP server), various output formats are available:

XML Format (default)

repomix --style xml

Markdown Format

repomix --style markdown

Plain Text Format

repomix --style plain

Advanced Configuration

Create a configuration file for custom settings:

repomix --init

This generates a repomix.config.json file with options for:

• Output file name and format
• File inclusion/exclusion patterns
• Security checks
• Token counting
• Code compression

Security Features

Repomix includes built-in security features:

• Secretlint integration to detect sensitive information
• Path validation to prevent directory traversal attacks
• Security checks on files before inclusion

These features help ensure that sensitive information isn't inadvertently shared when packaging code for AI analysis.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
