Using with Claude Desktop App

This tool is intended for use with the Claude Desktop app, which supports the Memory MCP protocol for knowledge graph storage and retrieval.

Configuring the Memory MCP Server

First, ensure you have the modelcontextprotocol-servers repository cloned locally.
Configure the Claude Desktop app to use the Memory MCP server by adding the following to your mcp_config.json file:

"memory": {
  "command": "npx",
  "args": [
    "-y",
    "@modelcontextprotocol/server-memory"
  ],
  "env": {
    "MEMORY_FILE_PATH": "/path/to/custom/memory.json"
  }
}

The above example shows a generic configuration. You should replace the paths with the actual locations on your system where you want to store your memory file.

💡 Personal tip: I store my memory.json in a Google Drive folder which automatically backs it up and makes it accessible across devices. Consider using a cloud storage solution for your memory file too!

Start Claude Desktop with this configuration to enable the memory features.
Use this Memory Visualizer to explore and debug the knowledge graph created by Claude.

Knowledge Graph Structure

Visualizes Anthropic's Memory MCP format:

Entities: Nodes with name, type, and observations (e.g., people, organizations)
Relations: Directed connections between entities in active voice (e.g., "works_at")
Observations: Atomic facts attached to entities

Use Cases

Debug entity relationships in AI memory
Analyze memory.json structures
Explore entity connections
Visualize graph growth over time
