What is the MCP GameBoy Server?

This is a server based on the Model Context Protocol (MCP) that allows large language models (LLMs) to interact with the GameBoy emulator. Through this server, you can control the GameBoy emulator, load game ROMs, and view the game screen, just like playing games on a real GameBoy.

How to use the MCP GameBoy Server?

You can use this server in multiple ways: 1) Automatically install it to Claude Desktop via Smithery. 2) Manually add it in FLUJO. 3) Manually install and run it through the command line. The server provides two control methods: a Web interface and an MCP client.

Applicable scenarios

This server is very suitable for: 1) Developers to test the interaction ability between LLMs and game emulators. 2) Educational scenarios to demonstrate how AI understands games. 3) Game AI research. 4) Adding game entertainment functions to LLMs.

Main features

Load ROMSupports loading various GameBoy game ROM files

Key controlSimulates all key operations of the GameBoy (up, down, left, right, A/B keys, start/select keys)
