Ansvar's US law server plugs federal and state legislation plus case law into Claude via their hosted gateway at gateway.ansvar.eu. It's the American counterpart to their EU-focused compliance stack, same citation contract and audit trail you get on GDPR or NIS2 queries but pointed at USC, state codes, and court opinions. Free tier is npm package us-law-mcp for local use, paid tier unlocks OAuth and the full gateway with cross-jurisdiction research, freshness dates, and source URLs baked into every answer. Reach for it when you need statutory text or case law inline without leaving your editor, and you want the same deterministic citation pipeline their GRC customers use for regulatory work.
