• quantconnect_mcp/src/tools/project_tools.py:620-693 (handler)

  The core handler function for the 'read_project_collaborators' tool. It authenticates with QuantConnect, sends a POST request to the 'projects/collaboration/read' endpoint with the project ID, parses the response, and returns the list of collaborators or an error message.

  @mcp.tool()
