git-mcp-server

A secure, git-aware MCP server for working with local repositories inside LM Studio (or any MCP host).

Features

• Full file access — read, write, edit, create, delete, move, search

• Shell execution — run commands in allowed directories with blocked dangerous patterns

• Complete git workflow — status, diff, log, branch, checkout, add, commit, push, pull, stash

• Path sandboxing — every operation is validated against your allowed directories; path traversal is blocked

• No network calls — inference stays local, this server never phones home

Prerequisites

• Node.js 18+

• npm

• git

Installation

# 1. Clone or copy this folder somewhere permanent
cd ~/tools
git clone <this-repo> git-mcp-server  # or just copy the folder

# 2. Install dependencies
cd git-mcp-server
npm install

# 3. Build
npm run build

After build, the server binary is at dist/index.js.

Configure LM Studio

Open Developer tab → Install → Edit mcp.json in LM Studio and add:

{
  "mcpServers": {
    "git-mcp": {
      "command": "node",
      "args": [
        "/absolute/path/to/git-mcp-server/dist/index.js",
        "--allow-dir", "/path/to/your/repo"
      ]
    }
  }
}

Multiple repos

{
  "mcpServers": {
    "git-mcp": {
      "command": "node",
      "args": [
        "/absolute/path/to/git-mcp-server/dist/index.js",
        "--allow-dir", "/home/user/projects/repo-one",
        "--allow-dir", "/home/user/projects/repo-two"
      ]
    }
  }
}

Using environment variable instead

{
  "mcpServers": {
    "git-mcp": {
      "command": "node",
      "args": ["/absolute/path/to/git-mcp-server/dist/index.js"],
      "env": {
        "ALLOWED_DIRS": "/home/user/projects/repo-one:/home/user/projects/repo-two"
      }
    }
  }
}

On Windows use ; as the separator in ALLOWED_DIRS.

Example prompts

Once connected in LM Studio:

• "Show me the status of the repo at ~/projects/myapp"

• "List all branches and tell me which has the most recent commit"

• "Read src/index.ts and refactor the error handling"

• "Stage all modified files and commit with the message 'fix: handle null case'"

• "Search for all usages of fetchUser across the repo"

• "Create a new branch called feature/auth and switch to it"

Recommended models for code work

Good tool-calling support is required. These work well locally:

• Qwen3 8B / 14B — excellent function calling, strong at code

• Llama 4 Scout — solid tool use, good multilingual support

• Mistral 7B Instruct — fast, reliable for single-tool workflows

Q4_K_M quantization is the recommended starting point.
