Config last verified Nov 10, 2026

The exact config to run LongMemory (formerly OpenMemory) in Claude Desktop — paste it in, restart, and the tools load.

Prerequisites

  • Claude Desktop installed.

Setup

1. Open ~/Library/Application Support/Claude/claude_desktop_config.json

On Windows the file lives at %APPDATA%\Claude\claude_desktop_config.json.

2. Add this configuration

Add to ~/Library/Application Support/Claude/claude_desktop_config.json

~/Library/Application Support/Claude/claude_desktop_config.json
json
{
  "mcpServers": {
    "openmemory": {
      "command": "npx",
      "args": [
        "-y",
        "longmemory",
        "mcp"
      ],
      "env": {
        "LM_DB_PATH": "<LM_DB_PATH>",
        "LM_TIER": "<LM_TIER>",
        "LM_EMBEDDINGS": "<LM_EMBEDDINGS>"
      }
    }
  }
}

3. Restart Claude Desktop and confirm the LongMemory (formerly OpenMemory) tools load.

Gotchas

Claude Desktop reads MCP servers from an "mcpServers" object, but the config file is stdio-only: it cannot dial a remote URL directly. To reach a remote server you bridge it locally by running "npx mcp-remote <url>" as the command. Native remote Connectors exist on paid plans, but not through this config file, so the bridge is the portable path.
