The create_agent_run example never stores the MCP tool response, but later reads response.id, so the sample code fails immediately with response is not defined. Capture the return value from use_mcp_tool before accessing it.

API_TOKEN defaults to a real-looking Codegen secret, so running this script without overriding the env var will leak and actively reuse the committed credential. Replace the fallback with a safe placeholder or require the env var to be set.
