Knowledge Graph Memory Server MCP Server について

I enhance the existing memory mcp server from the official mcp github, so big thanks and credits for creating this

概要

What is Knowledge Graph Memory Server?

A persistent memory implementation using a local knowledge graph, allowing Claude to remember user information across chats and learn from past errors through a lesson system.

How to use Knowledge Graph Memory Server?

Install via npx or Docker, configure the MCP client (e.g., Claude Desktop or Cursor), and add a system prompt for memory usage. The server exposes tools for managing entities, relations, observations, and lessons. Environment variable MEMORY_FILE_PATH can set a custom storage path.

Key features of Knowledge Graph Memory Server

  • Entities as primary nodes with name, type, and observations.
  • Directed relations stored in active voice.
  • Atomic observations attached to entities.
  • Lesson system for error pattern capture and success tracking.
  • Automatic file splitting when lines exceed 1000.

Use cases of Knowledge Graph Memory Server

  • Persistent memory for personal assistant across chat sessions.
  • Learning from past errors by storing lessons with solutions.
  • Building a knowledge graph of user preferences, relationships, and goals.

よくある質問

1

What data does the server store?

It stores entities (with type and observations), relations between entities, and lessons (error patterns, solutions, metadata) in local JSON files (`memory.json` and `lesson.json`).

2

How are lessons different from regular entities?

Lessons are special entities with structured error pattern information, solution steps, success rate tracking, and environmental context, designed for learning from errors.

3

What are the runtime requirements?

Requires Node.js and npm/npx or Docker. The server uses local file storage; no external database is needed.

4

How does file management work?

Files are automatically split if they exceed 1000 lines to maintain performance.

5

What transport/auth does the server use?

The server uses stdio transport (for Claude Desktop) and is intended for local use with no authentication mechanism described.
