makefilemcpserver
An MCP (Model Context Protocol) server that exposes Makefile targets as callable tools for AI assistants like Claude, Cursor, etc.
⚠️ ALPHA SOFTWARE - LOCAL USE ONLY ⚠️
This server executes Make commands with user-provided arguments. Only use in trusted environments. It intelligently parses out commands and args.
This almost certainly won't work flawlessly for your Makefile. In fact, it might not even work at all.
Installation
Prerequisites
- Node.js 16 or higher
makecommand available in PATH- A Makefile in your project directory
Quick Start
- Clone this repository:
git clone https://github.com/mparker3/makefilemcpserver.git
cd makefilemcpserver
- Install dependencies:
npm install
- Build the server:
npm run build
Usage
Add to your MCP server configuration:
{
"mcpServers": {
"makefilemcpserver": {
"command": "node",
"args": [
"/absolute/path/to/makefilemcpserver/build/index.js",
"/path/to/your/project"
]
}
}
}
The second argument (optional) specifies the directory containing your Makefile. If omitted, uses the current directory.
Example Makefile
# Build the project
build:
npm run build
# Run tests
test:
npm test
# Deploy to production
deploy: build test
./deploy.sh
This will expose tools: make_build, make_test, and make_deploy to Claude.
How It Works
- The server reads your Makefile at startup
- Each Make target becomes a tool with the name
make_<target> - Comments directly above targets become tool descriptions
- MCP clients can then run any target with optional arguments. We do some best-effort parsing of args from docs + commands, a better approach would just be to offload it to yet another LLM call(s) at startup.
Security Considerations
⚠️ WARNING: This server executes shell commands via Make. It currently has minimal input validation.
- Anything you expose in your Makefile, any MCP client will have access to. Highly recommend running locally only.
- The server does some de rigeur input sanitization, but no guarantees that an enterprising security researcher can't figure out a way around it.
Development
# Install dependencies
npm install
# Build once
npm run build
# Build and watch for changes
npm run watch
# Run the MCP Inspector for debugging
npm run inspector
Debugging
Since MCP servers communicate over stdio, use the MCP Inspector:
npm run inspector
Then open the provided URL to access debugging tools.
