🐟 MCP server connecting AI systems to Stockfish chess engine

概要

A Model Context Protocol server that lets your AI talk to Stockfish. Because apparently we needed to make chess engines even more accessible to our silicon overlords. 🧠⚡🖥️ Your LLM thinks, Stockfish calculates, you pretend you understand the resulting 15-move tactical sequence. This creates a bridge between AI systems and the Stockfish chess engine via the MCP protocol. It handles multiple concurrent sessions because your AI probably wants to analyze seventeen positions simultaneously while you're still figuring out why your knight is hanging. Built on mark3labs/mcp-go. Because reinventing wheels is for people with too much time.

mcp-stockfish 🐟

A Model Context Protocol server that lets your AI talk to Stockfish. Because apparently we needed to make chess engines even more accessible to our silicon overlords.

🧠⚡🖥️ Your LLM thinks, Stockfish calculates, you pretend you understand the resulting 15-move tactical sequence.

What is this?

This creates a bridge between AI systems and the Stockfish chess engine via the MCP protocol. It handles multiple concurrent sessions because your AI probably wants to analyze seventeen positions simultaneously while you’re still figuring out why your knight is hanging.

Built on mark3labs/mcp-go. Because reinventing wheels is for people with too much time.

Features

  • 🔄 Concurrent Sessions: Run multiple Stockfish instances without your CPU crying
  • ⚡ Full UCI Support: All the commands you need, none of the ones you don’t
  • 🎯 Actually Works: Unlike your last side project, this one has proper error handling
  • 📊 JSON Everything: Because apparently we can’t just use plain text anymore
  • 🐳 Docker Ready: Containerized for when you inevitably break your local setup

Supported UCI Commands ♟️

Command Description
uci Initializes the engine in UCI mode
isready Checks if the engine is ready. Returns readyok
position startpos Sets up the board to the starting position
position fen [FEN] Sets up a position using FEN notation
go Starts the engine to compute the best move
go depth [n] Searches n plies deep. Example: go depth 10
go movetime [ms] Thinks for a fixed amount of time in milliseconds. Example: go movetime 1000
stop Stops current search
quit Closes the session
