Knowledge Graph Memory
OfficialCreates a local knowledge graph that lets Claude remember information about you and your conversations across different chat sessions. Stores entities, relationships, and observations in a persistent semantic network.
Build and query persistent semantic networks for data management. A basic implementation of persistent memory using a local knowledge graph. This lets Claude remember information about the user across chats.
What it does
- Create entities and relationships in knowledge graph
- Add observations to existing entities
- Search nodes by query
- Delete entities, relations, or observations
- Read entire knowledge graph structure
- Open specific nodes by name

About Knowledge Graph Memory
Knowledge Graph Memory is an official MCP server published by anthropic that provides AI assistants with tools and capabilities via the Model Context Protocol. Build persistent semantic networks for enterprise & engineering data management. Enable data persistence and memory acro It is categorized under ai ml. This server exposes 9 tools that AI clients can invoke during conversations and coding sessions.
How to install
You can install Knowledge Graph Memory in your AI client of choice. Use the install panel on this page to get one-click setup for Cursor, Claude Desktop, VS Code, and other MCP-compatible clients. This server runs locally on your machine via the stdio transport.
License
Knowledge Graph Memory is released under the NOASSERTION license.
Tools (9)
Create multiple new entities in the knowledge graph
Create multiple new relations between entities in the knowledge graph. Relations should be in active voice
Add new observations to existing entities in the knowledge graph
Delete multiple entities and their associated relations from the knowledge graph
Delete specific observations from entities in the knowledge graph
Model Context Protocol servers
This repository is a collection of reference implementations for the Model Context Protocol (MCP), as well as references to community-built servers and additional resources.
[!IMPORTANT] If you are looking for a list of MCP servers, you can browse published servers on the MCP Registry. The repository served by this README is dedicated to housing just the small number of reference servers maintained by the MCP steering group.
[!WARNING] The servers in this repository are intended as reference implementations to demonstrate MCP features and SDK usage. They are meant to serve as educational examples for developers building their own MCP servers, not as production-ready solutions. Developers should evaluate their own security requirements and implement appropriate safeguards based on their specific threat model and use case.
The servers in this repository showcase the versatility and extensibility of MCP, demonstrating how it can be used to give Large Language Models (LLMs) secure, controlled access to tools and data sources. Typically, each MCP server is implemented with an MCP SDK:
- C# MCP SDK
- Go MCP SDK
- Java MCP SDK
- Kotlin MCP SDK
- PHP MCP SDK
- Python MCP SDK
- Ruby MCP SDK
- Rust MCP SDK
- Swift MCP SDK
- TypeScript MCP SDK
