Gearboy MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCP server for Gearboy Nintendo Game Boy / Game Boy Color emulator.
Gearboy is an accurate, cross-platform Game Boy / Game Boy Color / Super Game Boy emulator written in C++ that runs on Windows, macOS, Linux, BSD and RetroArch, with an embedded MCP server for debugging and tooling.
Once Gearboy is connected, these are the calls the assistant has available:

Use the following commands to build:Libretro — The Libretro tool exposed by this serverskills on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Gearboy's toolset — Windows, macOS, Linux and 1 more — is a fair guide to whether it matches your workflow. It is maintained by drhelius; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
