QuestionQ28

Tool Design & MCP Integration

Production logs show inconsistent error handling: when lookup_order fails, the agent sometimes retries 5+ times (wasteful when the order ID does not exist), sometimes escalates immediately (premature for temporary network issues), and sometimes asks users for clarification (inappropriate when the issue is a backend permission error). Investigation shows that your MCP tool returns uniform error responses: \{"isError": true, "content": [\{"type": "text", "text": "Operation failed"\}]\}. The agent cannot differentiate among error types. What is the most effective improvement?

Explanation

MCP tool execution errors should provide actionable feedback to the language model. Structured metadata identifying the error category, whether it is retryable, and its cause enables consistent handling: retry transient failures, avoid retries for validation failures such as a nonexistent order ID, and surface permission issues through the proper escalation path.
