README

QuantConnect MCP Server

The QuantConnect MCP Server is a bridge for AIs (such as Claude and OpenAI o3 Pro) to interact with our cloud platform. When equipped with our MCP, the AI can perform tasks on your behalf through our API such as updating projects, writing strategies, backtesting, and deploying strategies to production live-trading.

This is the OFFICIAL implementation of QuantConnect's MCP, maintained by the QuantConnect team. We recommend using the official version to ensure security of your code and API tokens. Our implementation is tested and dockerized for easy cross-platform deployment.

Getting Started

To connect local MCP clients (like Claude Desktop) to the QC MCP Server, follow these steps:

  1. Install and open Docker Desktop.
  2. Install and open Claude Desktop.
  3. In Claude Desktop, click File > Settings > Developer > Edit Config.
  4. Edit the claude_desktop_config.json file to include the following quantconnect configuration:
json
{
  "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"
      }
    }
  }
}

To get your user Id and API token, see Request API Token.

Our MCP server is multi-platform capable. The options are linux/amd64 for Intel/AMD chips and linux/arm64 for ARM chips (for example, Apple's M-series chips).

If you simultaneously run multiple agents, set a unique value for the AGENT_NAME environment variable for each agent to keep record of the request source.

  1. Restart Claude Desktop.

    Claude Desktop automatically pulls our MCP server from Docker Hub and connects to it.

To view all the MCP clients and the features they support, see the Feature Support Matrix in the MCP documentation.

To keep the Docker image up-to-date, pull the latest MCP server from Docker Hub in the terminal.

docker pull quantconnect/mcp-server

If you have an ARM chip, add the --platform linux/arm64 option.
