MCP server that gives AI coding agents instant access to Thomson MO5 technical documentation via semantic search. Powered by a RAG backend, but zero configuration required: just plug and play with the public instance at retrocomputing-ai.cloud. Part of a complete MO5 development toolchain: - SDK MO5 (https://github.com/thlg057/sdk_mo5): C library optimized for CMOC with MO5-specific abstractions - MO5 Project Template (https://github.com/thlg057/mo5_template): Ready-to-use project scaffold with automated Makefile - This MCP Server (https://github.com/thlg057/mo5-mcp-server): The AI assistant that ties it all together: answers technical questions, searches docs, and generates assets. Ideal for retrocomputing enthusiasts developing in C for the Thomson MO5 with modern agentic tooling.
