Error Handling And Response Validation With Typed Error Codes

Model Context Protocol Servers

Unique: Provides typed error codes and structured error responses that allow clients to programmatically handle different error types, enabling automatic error recovery and graceful degradation. Unlike generic error messages, typed errors enable intelligent error handling in LLM agents.

vs others: More actionable than generic error messages because clients can parse error codes and implement specific recovery strategies; more robust than silent failures because errors are explicitly propagated to clients.
