Developer FarPangolin7657 shares UML, an open-source project that enables shared memory between Claude and ChatGPT via a remote MCP server. It stores memories as a knowledge graph with clickable nodes, editable rules, and supports user auth and tenant isolation. Built on Cloudflare Workers, D1, Vectorize, and Durable Objects, it uses exact/alias + BM25 + vector fusion for recall without LLM calls. Free and open source, the author seeks feedback on improving natural language trigger for memory tools.
