git-commit-aider MCP Server

Make git commits on behalf of AI, so that you can track AI contribution in your codebase.

This is a TypeScript-based MCP server that provides a tool to commit staged changes in a Git repository while appending "(aider)" to the committer's name.

Features

This MCP server provides only one tool:

commit_staged - Commit staged changes with a specific message.

Takes message (string, required) as the commit message.
Takes cwd (string, optional) to specify the working directory for the git command.
Appends "(aider)" to the committer name automatically.
Reads committer name and email from environment variables (GIT_COMMITTER_NAME, GIT_COMMITTER_EMAIL) if set, otherwise falls back to git config user.name and git config user.email.

With this tool installed in your code editor, you can prompt the AI by something like:

Commit the changes for me

This usually happens after the AI has made some changes to your codebase, so often times AI is able to provide a good commit message from the context.

Commits with "(aider)" can be picked up by aider --stats command, which will show you the contribution of AI in your codebase.

Installation

To use this server, add its configuration to your MCP settings file.

{
  "mcpServers": {
    "git-commit-aider": {
      "command": "npx",
      "args": ["mcp-git-commit-aider"]
    }
  }
}

The committer information is retrieved from:

Environment variables GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL, which follows git's convention.
Output of git config user.name and git config user.email commands.

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Sample MCP config:

{
  "mcpServers": {
    "git-commit-aider": {
      "command": "node",
      "args": [
        "/path/to/git-commit-aider/build/index.js"
      ]
    }
  }
}

(Replace /path/to/git-commit-aider with the actual path to this server directory.)

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
