What it does

An active MCP reference server (Node.js) that gives an AI client durable memory by storing facts as a local knowledge graph — entities, relations, and observations — persisted to a JSONL file, so an assistant remembers preferences and context across conversations. All operations are deterministic graph mutations/queries. Runs locally over stdio.

Example prompts

Remember that I prefer TypeScript and concise answers.
What do you remember about my current project?
