Mo5 Mcp Server
Built for writing C programs on the vintage Thomson MO5 microcomputer using the 6809 processor and CMOC compiler. Connects to a public RAG server at retrocomputing-ai.cloud to run semantic searches across MO5 technical documentation and hardware specs. Exposes tools to generate bootable .fd disk images, convert them to SDDrive format, and turn PNG graphics into C sprite headers. Works alongside the sdk_mo5 C library and mo5_template project skeleton. Useful if you're doing retro 6809 development and want an AI assistant that actually knows the MO5 architecture, memory map, and toolchain quirks without hallucinating.

Readme
MO5 MCP Server (RAG Connector)
This MCP server (Model Context Protocol) acts as a bridge between modern AI agents (Claude Desktop, Augment, Cursor) and the Thomson MO5 ecosystem.
It allows access to an expert knowledge base and manipulation of MO5 heritage files.
It provides semantic search tools, documentation resources, and expert prompts to facilitate development around the Thomson MO5 microcomputer.
🏗️ MO5 Development Ecosystem
This server is part of a complete toolchain for modern 6809 development:
- SDK MO5 : https://github.com/thlg057/sdk_mo5
C library optimized for CMOC. - MO5 Project Template : https://github.com/thlg057/mo5_template
Project template with automated Makefile. - This MCP Server : The assistant that connects everything, answers technical questions, and generates assets.
🌐 RAG Infrastructure (Artificial Intelligence)
The server relies on a Retrieval-Augmented Generation architecture to provide accurate answers based on real technical documentation.
