Lean Mathlib 4 Documentation Search MCP Server

This project provides a Minimal MCP (Model Context Protocol) Server for searching Lean Mathlib 4 documentation. It allows LLMs to query Lean Mathlib 4 declarations and retrieve relevant documentation links and details. The MCP server is only available for VSCode at the moment.

Features

• Search Lean Mathlib 4 Documentation: Query the documentation for declarations, modules, and instances.
• MCP Server Integration: Implements the MCP protocol for seamless integration with tools.
• Local Data Handling: Downloads and processes Lean Mathlib 4 documentation data locally after the first run.

Prerequisites

• Python 3.11 or higher
• requests library
• mcp MCP Server library

Installation

1. Clone the repository:

   git clone https://github.com/CriticalLine/lean-mathlib-docs-mcp.git
   cd lean-mathlib-docs-mcp

2. Install the required Python dependencies:

   conda env create -f environment.yml
   conda activate lean-mathlib-docs-env

3. Ensure the mcp.json file is correctly configured in the .vscode folder or the project root.

Usage

1. VSCode will automatically start the MCP server when you launch it with the appropriate configuration.
2. Query the server by explicitly using #search_lean_doc <query> or tell the LLM to use the search function.
