MCP server enabling persistent memory for Claude through a local knowledge graph. This lets Claude remember information about the user across chats.
Overview
The Knowledge Graph Memory Server is an enhanced implementation of persistent memory utilising a local knowledge graph, designed to enable Claude to retain user information across conversations. This fork, developed by Shane Holloman, focuses on local development by allowing a customisable `--memory-path` for storing memory data, moving away from the ephemeral memory installation method.

By integrating this server, Product Designers, Project Managers, and Design Leaders can ensure that Claude maintains context and personalisation throughout user interactions, leading to more coherent and tailored experiences.
Key Features
- The memory MCP server is hosted locally on the user's device, allowing for unlimited memories
- Persistent user information retention across chats.
- Local knowledge graph implementation for enhanced data control.
Capabilities
- Creation of multiple new entities in the knowledge graph.
- Establishment of relations between entities.
- Addition of new observations to existing entities.
- Deletion of entities and their associated relations.
- Removal of specific observations from entities.
- Deletion of specific relations from the graph.
- Retrieval of the entire knowledge graph structure.
- Search functionality across entity names, types, and observation content.
- Retrieval of specific nodes by name, including their relations.
How It Works
- Entities are defined with a unique name, entity type, and a list of observations.
- Relations are established to define directed connections between entities, stored in active voice.
- Observations are discrete pieces of information about an entity, stored as strings and attached to specific entities.
- The server provides tools for creating, retrieving, updating, and deleting entities and relations, as well as searching the memory based on natural language queries.
