Installation

You can install this package via npm:

# Global installation (recommended)
npm install -g emacs-mcp-server

# Local installation
npm install emacs-mcp-server

Setup with Claude Code

Once installed, you can add the MCP tools to Claude Code:

# Register tools with Claude Code
claude mcp add emacs-mcp-open emacs-mcp-open
claude mcp add emacs-mcp-magit emacs-mcp-magit
claude mcp add emacs-mcp-check emacs-mcp-check
claude mcp add emacs-mcp-list emacs-mcp-list

Manual Setup (Development)

For development or manual setup:

# Clone the repository
git clone https://github.com/toastynerd/emacs-mcp-server.git
cd emacs-mcp-server

# Install dependencies
npm install

# Add direct tools to Claude Code
claude mcp add emacs-mcp-open ./src/direct-tool.js
claude mcp add emacs-mcp-magit ./src/direct-tool.js
claude mcp add emacs-mcp-check ./src/direct-tool.js
claude mcp add emacs-mcp-list ./src/direct-tool.js

Adding Git MCP (Recommended)

For better repository exploration and documentation access, add git-mcp:

# Add git-mcp to Claude Code
claude mcp add --transport sse git-mcp https://gitmcp.io/idosal/git-mcp

This allows Claude to access repository documentation and code context through the Model Context Protocol.

Usage

After installation, you can use the MCP tools with Claude Code:

/mcp emacs-mcp-open file_path="/path/to/your/file.txt"
/mcp emacs-mcp-magit repo_path="/path/to/your/repo"
/mcp emacs-mcp-check
/mcp emacs-mcp-list
