Knowledge Graph Memory Server for AI models using Model Context Protocol.
The `mcp-knowledge-graph` is an advanced implementation of persistent memory using a local knowledge graph, allowing AI models to remember user information across interactions. It is designed to work with any AI model that supports the Model Context Protocol (MCP) or function calling capabilities. This server is a fork of the original Memory Server, offering a more robust solution by avoiding the ephemeral memory npx installation method. The server uses entities, relations, and observations to structure and store information, enabling AI models to maintain context and improve user interaction over time. The server is compatible with various AI platforms, including Claude, GPT, and Llama, and can be customized with a specific memory path for data storage.
Features
- Persistent memory using a local knowledge graph
- Customizable memory path for data storage
- Compatible with any AI model supporting MCP or function calling
- Entities, relations, and observations for structured information storage
- Fork of the original Memory Server with improved implementation
