The HTTP Status Reference Lookup MCP server provides a deep dive into the semantics of HTTP response codes. It allows you to query specific details for any status code, including its official name, RFC reference, and whether it is cacheable or retryable. You can use get_status_metadata to retrieve technical definitions, list_codes_by_category to browse ranges like 2xx or 4xx, and check_scenario_consistency to validate if a status code matches your payload's content, helping prevent semantic mismatches in API responses.
