Ansvar Gateway is a single MCP endpoint for regulatory compliance work. Ask for the law and it returns the actual provisions — GDPR, NIS2, the EU AI Act, DORA, CRA, and national statutes across the EU and dozens of other jurisdictions, plus standards, case law, preparatory works, and regulator guidance. Every row carries a paragraph-level citation with source URL, publisher, and license, fetched from the official publisher, never a mirror. It also serves live CVE/KEV/EPSS vulnerability data and MITRE ATT&CK/CAPEC/CWE, and runs guided compliance workflows (threat modeling, DPIA, gap analysis) from your own MCP client — Claude, Copilot, ChatGPT, or any MCP-capable agent. If a source is unavailable it says so rather than answering from model memory. Auth is OAuth 2.1 with Dynamic Client Registration; a free tier is available for business users at ansvar.eu.
