Universal Memory is a remote server designed to serve as a persistent knowledge graph, acting as long-term memory for AI assistants. It meticulously stores entities (such as people, companies, projects), observations (facts associated with these entities), and the relations connecting them. This robust system allows any MCP-compatible AI assistant, including popular platforms like Claude, ChatGPT, Gemini, and VS Code Copilot, to access and leverage a continuous memory, enhancing interactions by recalling past information. Built on Cloudflare Workers, it features hybrid search capabilities combining semantic similarity with keyword matching, OAuth protection for secure access, and an interactive visualization of the knowledge graph.
