Project Overview

This project creates a bridge between modern AI-assisted development (e.g. GitHub Copilot, Claude Desktop) and retro computing (MSX systems) by providing:

Emulator Control: Launch, configure, manage openMSX instances, and replay timelines.
Media Management: Handle ROM cartridges, floppy disks, and cassette tapes.
BASIC Programming Support: Tools to facilitate BASIC language programming and development.
Debugging Tools: Full CPU debugging with breakpoints, memory inspection, and step execution.
Video Control: VDP register manipulation and screen capture.
Memory Operations: Read/write RAM, VRAM, and I/O port access.
Automation: Keyboard input simulation and savestate management.
Vector DB Integration: Query an embedded vector database with MSX resources for development support.
Hybrid Mode: This MCP server supports hybrid access mode (STDIO and HTTP transports).
