Implementation Reference

• acp_mcp_server/run_orchestrator.py:344-358 (handler)

  The handler function for the 'list_active_runs' tool. It iterates over the orchestrator's active_runs dictionary, extracts key information for each run, and returns a formatted JSON string listing all active runs.

  @mcp.tool()
  async def list_active_runs() -> str:
      """List all active runs"""
      
      runs_info = []
      for run_id, run in orchestrator.active_runs.items():
          runs_info.append({
              "run_id": run_id,
              "agent_name": run.agent_name,
              "status": run.status,
              "has_error": run.error is not None
          })
      
      return json.dumps(runs_info, indent=2)

• acp_mcp_server/server.py:87-87 (registration)

  Invocation of register_orchestrator_tools which defines and registers the list_active_runs tool (along with other orchestrator tools) to the FastMCP instance.
