Geargrafx MCP Server
Connect Geargrafx PC Engine / TurboGrafx-16 emulation to your MCP agent for HuCard-era builds, ports, and automated play validation.
Overview
Geargrafx MCP Server is a Build-phase MCP server that lets AI agents control Geargrafx PC Engine / TurboGrafx-16 emulation through stdio packages.
What is this MCP server?
- Geargrafx MCP server for PC Engine / TurboGrafx-16 emulation
- Four release .mcpb builds: macOS arm64/x64 and Windows arm64/x64 at v1.7.9
- stdio Model Context Protocol transport
- Enables agent-side HuCard and PCE ROM exercise without custom JNI or GUI macros
- Console-specific drhelius MCP entry—pair with other Gear servers only if you multi-target retro platforms

What problem does it solve?
PC Engine projects slow down when agents cannot boot HuCard images and confirm fixes inside an accurate TurboGrafx core.
Who is it for?
Indie retro devs and agent builders focused on PC Engine / TurboGrafx-16 who want MCP-native emulation in the IDE.
Skip if: Teams with no PCE target, or workflows that require only cloud CI without local emulator binaries.
What do I get? / Deliverables
With Geargrafx MCP registered, your agent runs PCE ROMs locally and tightens the feedback loop between patches and in-emulator behavior.
- Active stdio MCP session to Geargrafx 1.7.9
- Agent-controlled PCE emulation for test and debug
- Documented local ROM workflow the agent can reference

Journey fit
TurboGrafx tooling sits in Build because engineers add it while implementing or testing game logic, not during SEO launch or production monitoring. Agent-tooling captures MCP stdio access so models invoke emulator operations as tools during coding sessions.
How it compares
Dedicated PCE MCP emulator bridge, not a cross-platform game engine plugin marketplace listing.
Common Questions / FAQ
Who is Geargrafx MCP Server for?
Builders and tinkerers using MCP coding agents who need TurboGrafx-16 / PC Engine emulation as an agent tool.
