Overview

Memory MCP Server is a Model Context Protocol server that provides knowledge graph management capabilities, enabling AI assistants to maintain memory across conversations.

To use the Memory MCP Server, you can either download the pre-built binary or build it from source. After installation, configure it with your AI assistant to manage knowledge graphs effectively.

Knowledge Graph Storage: Persistent storage of entities and their relationships. - Entity Management: Create, read, update, and delete entities. - Relation Tracking: Manage relationships between entities. - Observation System: Track observations about entities over time. - Powerful Search: Search for nodes by name, type, or observation content. - Persistent Storage: Data persists in a simple JSON format.

Long-term memory for AI assistants.
Knowledge management for organizing information.
Relationship tracking between entities.
Context persistence across sessions.
Maintaining structured records of events and activities.

Add to your AI client

Use these steps to connect Memory MCP Server in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "memory-mcp-server-okooo5km": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory-mcp-server-okooo5km"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "memory-mcp-server-okooo5km": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory-mcp-server-okooo5km"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "memory-mcp-server-okooo5km": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory-mcp-server-okooo5km"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "memory-mcp-server-okooo5km": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory-mcp-server-okooo5km"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "memory-mcp-server-okooo5km": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory-mcp-server-okooo5km"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "memory-mcp-server-okooo5km": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory-mcp-server-okooo5km"
      ]
    }
  }
}
