Implementation Reference
- Core handler function for the 'liquidate_live_algorithm' tool, decorated with @mcp.tool(). It authenticates, prepares a POST request to QuantConnect's 'live/update/liquidate' endpoint with the project_id, and returns success/error responses based on the API result.@mcp.tool() async def liquidate_live_algorithm(project_id: int) -> Dict[str, Any]: """ Liquidate all positions in a live algorithm.
