      "url": "https://www.quantconnect.com/api/v2/mcp"
    }
  }
}

15. Save and close the ~ / AppData / Roaming / devin / mcp_config.json file.

18. In the Authorize MCP Server form, select the organization you want to connect to and then click Authorize.


Devin Desktop should now show all the tools available through the QuantConnect MCP Server.


19. In Devin Desktop, create a new project or open an existing one.
20. Press Ctrl+L to open Devin Local and begin interacting with the agent.

To backtest and live trade with the local Deployment Target, install Docker Desktop. The installation process depends on if your machine uses Windows, macOS, or Linux.

Devin Desktop supports several LLMs that you can use in the Devin Local panel, including GPT, Claude, and Gemini. To change the model, click the model name at the bottom of the Devin Local panel and then click the name of the model to use.

To view all the available models, see AI Models in the Devin documentation.

There are no quotas on the QuantConnect API, but Devin Desktop and the LLMs have some. To view the quotas, see Quota-Based Usage in the Devin documentation and see the quotas of the model you use.

The following sections explain some issues you may encounter and how to resolve them.

Service Outages

The MCP server relies on the QuantConnect API and the client application. To check the status of the QuantConnect API, see our Status page. To check the status of Devin Desktop, see the Devin Status page. To check the status of the LLM, see its status page. For example, Claude users can see the Anthropic Status page.

The following examples demonstrate the MCP server with Devin Local in Devin Desktop.

Example 1: Hello World

To test the server and client are working and connected, enter the following prompt into the Devin Local chat:

> Read the open project.

The agent should call the read_open_project tool.
