by stevenwangler
Reference MCP server providing persistent knowledge graph memory for LLMs to store and retrieve information.
What it does
This is a reference implementation of an MCP Memory Server that uses a knowledge graph to provide persistent memory. It allows AI models to create entities, define relationships between them, and perform semantic searches to maintain a consistent context across different conversations.
Tools
create_entities: Adds new entities to the knowledge graph.create_relations: Establishes links between existing entities.search_nodes: Finds relevant entities using semantic similarity.get_entity_details: Retrieves specific information about a known entity.delete_entity: Removes an entity from the memory store.
