QuestionQ7

Tool Design & MCP Integration

Your control_device tool controls smart-home devices through external APIs. If a device fails to respond within the timeout period, the tool returns an error. Production logs indicate that the agent only tells users, “the device is not responding,” without providing useful next steps. Which error-response structure would best allow the agent to provide helpful follow-up?

Explanation

An error response should accurately signal the timeout while providing actionable, user-relevant context. Including a likely cause and suggested troubleshooting steps gives the agent information it can immediately turn into useful follow-up guidance.
