recent_rules

Pack: federal-register · Endpoint: https://gateway.pipeworx.io/federal-register/mcp

Browse the most recently published final rules and regulations from the Federal Register, with no topic filter — returns whatever was published most recently across every agency (FAA airworthiness directives, Coast Guard safety zones, EPA tolerance exemptions, etc.). For questions about a specific topic (“EV tax credits”, “AI rules”, “drug pricing”), use search_documents instead. Returns title, abstract, agency, effective dates, significance.
