QuantConnect MCP Server

How to use

You connect an MCP client to the server by running the MCP inside a container and pointing your client to it. The official implementation is designed to be multi‑platform and works with Docker. Use a unique agent name for each client to keep requests traceable.

How to install

Prerequisites you need before starting: Docker Desktop installed on your machine. If you plan to run on an ARM chip, ensure you use the correct platform flag when pulling or running the image.

1. Install and open Docker Desktop.

2. Install and open Claude Desktop.

3. In Claude Desktop, go to File > Settings > Developer > Edit Config and add the QuantConnect MCP server configuration.

{
  "mcpServers": {
    "quantconnect": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e", "QUANTCONNECT_USER_ID",
        "-e", "QUANTCONNECT_API_TOKEN",
        "-e", "AGENT_NAME",
        "--platform", "<your_platform>",
        "quantconnect/mcp-server"
      ],
      "env": {
        "QUANTCONNECT_USER_ID": "<your_user_id>",
        "QUANTCONNECT_API_TOKEN": "<your_api_token>",
        "AGENT_NAME": "MCP Server"
      }
    }
  }
}

Additional setup commands

Claude Desktop will automatically pull the MCP server image from the container registry and connect once you restart the client.

The MCP server image can be updated by pulling the latest version from the container registry. Use the command shown here to fetch the latest image. If you are on ARM, include the platform flag when pulling.

docker pull quantconnect/mcp-server
```
If you have an ARM chip, add the platform option when pulling.
