Code2Prompt MCP server

The code2prompt-mcp server analyzes codebases to generate contextual prompts for AI assistants, making it easier for them to understand and work with your code repositories. It leverages the high-performance code2prompt-rs Rust library to extract and structure code context in a format optimized for language models.

Installation

Before you begin, ensure you have Rye installed on your system for dependency management.

Follow these steps to install the code2prompt-mcp server:

# Clone the repository
git clone https://github.com/odancona/code2prompt-mcp.git
cd code2prompt-mcp

# Install dependencies with Rye
rye build

This will install all required dependencies specified in the pyproject.toml file into a .venv directory.

Running the Server

To start the MCP server, use the following command:

rye run python code2prompt_mcp.main

Once running, the server will be ready to analyze codebases and provide contextual prompts that can be consumed by AI assistants.

Testing with MCP Inspector

You can verify that your server is working correctly using the MCP Inspector tool:

npx @modelcontextprotocol/inspector python -m code2prompt_mcp.main

This tool helps validate that your MCP server is properly configured and responding to requests.

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.
