Memory MCP Server
Persistent knowledge-graph memory for LLM clients — store, recall, and link facts across sessions.
Memory MCP Server is a persistent knowledge-graph memory for LLM clients — store, recall, and link facts across sessions. Implements the Model Context Protocol (MCP) for standardized integration with compatible LLM clients.
About Memory MCP Server
Memory MCP Server is an MCP server that gives compatible LLM clients persistent memory built on a knowledge graph.
It uses a knowledge graph to link related facts and entities, and that memory persists across separate client sessions rather than resetting each time. It runs on macOS, Windows, and Linux, including via the command line.
It fits people who want an assistant to store, recall, and connect facts over time instead of starting fresh every session. It needs an MCP-compatible client to be useful, and it runs as a background server with no standalone graphical interface, so all interaction happens through the client.
Among MCP servers it is an infrastructure piece — memory rather than an integration with an outside app — that other tools and sessions read from.
