Knowledge Graph Memory
by modelcontextprotocol · Databases · mcp-server, npm
Build and query persistent semantic networks for data management.
This knowledge graph memory server, developed by Anthropic, provides a persistent memory system for language models using a local graph database. It enables AI agents to create, query, and update entities, relations, and observations through a controlled API. By storing information as a semantic network, it allows AI systems to build and maintain complex knowledge structures over time. The server integrates with Claude Desktop via NPM and focuses on personalization use cases. This implementation is particularly useful for AI assistants designed to remember user preferences, track relationships between people and organizations, or accumulate domain knowledge across conversations.
