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

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…
