AI tools need structured errors, not raw exceptions, for agent reasoning

By PulseAugur Editorial · [1 sources] ·

This article discusses the importance of structured error handling for tools used by AI agents. It argues that instead of returning raw exceptions, tools should provide machine-readable error codes and messages. This allows the AI agent to understand the nature of the failure, such as a rate limit, and take appropriate action like retrying, rather than defaulting to a generic error and giving up. The author emphasizes defining a clear contract for tool errors, including a 'retryable' flag, to enable agents to manage failures effectively and improve user experience. AI

IMPACT Ensures AI agents can reliably handle tool failures, improving robustness and user experience.

    When an MCP Tool Errors: Structured Tool Errors vs a Raw Exception

    <p><strong>Quick answer:</strong> An MCP tool should return a structured, machine-readable error when something goes wrong, not let a raw exception bubble up. The agent calling the tool has to decide whether to retry, fix its parameters, or ask the user, and it can only do that w…
