Code2Prompt MCP server

Code2prompt-mcp is a server that helps generate contextual prompts from codebases, making it easier for AI assistants to understand and work with your code repositories. It leverages the high-performance code2prompt-rs Rust library to analyze codebases and produce structured summaries optimized for AI consumption.

Installation

The project uses Rye for dependency management, so you'll need to have Rye installed on your system first.

To install code2prompt-mcp:

# 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 the required dependencies specified in the pyproject.toml file in the .venv directory.

Usage

To run the MCP server, use the following command:

rye run python code2prompt_mcp.main

Once the server is running, it will analyze your codebase and provide structured summaries that can be consumed by AI assistants. This helps bridge the gap between your code and language models by extracting relevant context in an optimized format.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "code2prompt" '{"command":"python","args":["-m","code2prompt_mcp.main"]}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "code2prompt": {
            "command": "python",
            "args": [
                "-m",
                "code2prompt_mcp.main"
            ]
        }
    }
}

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "code2prompt": {
            "command": "python",
            "args": [
                "-m",
                "code2prompt_mcp.main"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
