Limitless

Connect Limitless MCP Server to your AI assistants so you can access and search your lifelogs, Pendant recordings, and personal notes directly from your AI workflows. This MCP server lets you run the integration locally or via a simple command, and exposes your memories to compatible assistants for natural language queries, daily summaries, and memory exports.

How to use

You can connect your AI assistant to Limitless MCP Server by running the MCP server locally and registering it in your assistant’s configuration. Use the provided runtime command to start the server, then point your assistant to the local MCP endpoint or a configured command that launches the server. Once connected, you can ask your AI to list lifelogs, search memories by date or source, get daily summaries, and export memories as markdown. You can also star important memories and ask AI-powered questions about past conversations and meetings. All actions are performed through the MCP layer, removing the need to switch apps to access your lifelogs.

How to install

# Global installation (recommended)
npm install -g @utlyze/limitless-mcp-server

# Direct usage with npx (recommended for quick start)
npx @utlyze/limitless-mcp-server

Configuration

Configure your API key and connect the MCP server to your AI assistant. You will set LIMITLESS_API_KEY in the server environment and then reference the server in your assistant’s mcp configuration.

{
  "mcpServers": {
    "limitless": {
      "command": "npx",
      "args": ["-y", "@utlyze/limitless-mcp-server"],
      "env": {
        "LIMITLESS_API_KEY": "your-api-key"
      }
    }
  }
}

Environment variables

Set these environment variables when running the MCP server. The LIMITLESS_API_KEY is required. Optionally set LIMITLESS_BASE_URL to customize the API base URL and DEBUG for verbose logging.

LIMITLESS_API_KEY=your-api-key
LIMITLESS_BASE_URL=https://api.limitless.ai/v1
DEBUG=false

Notes on usage with clients

The server supports two installation modes: a global installation for all users or direct usage with npx for quick experimentation. In both cases, you run the MCP server and then configure your AI assistant to use the Limitless MCP server by referencing the same command and environment variables shown above.

Troubleshooting

If you encounter issues, verify that LIMITLESS_API_KEY is correctly set and that the server process is running. Use DEBUG=true to enable extra logging for diagnosing connectivity or authentication problems. Ensure your internet connection is stable and that the API base URL is accessible.

Security

Keep your API key secret and never commit it to version control. Use the provided environment variable to inject the key at startup, and avoid exposing credentials in logs or shared configurations.
