eu.ansvarPublished by ansvar.euOfficial publisherv1.0.892a470aUpdated Oct 24, 2026
Cited EU & global law, regulations & security frameworks via Ansvar Gateway. OAuth, free + paid.
The publisher's own server: Ansvar: Dutch Law
Overview
Remote MCP server giving assistants cited search and retrieval of EU and global law, regulations, security frameworks and threat intelligence.
- What you can do
- Search legislation, regulations, standards and threat intel across jurisdictions, with article-level citations
- Resolve a canonical reference to the exact provision or court decision text
- List live corpora and jurisdictions by domain
- On paid tiers, fan out to case law, preparatory works and agency guidance, and run workflow prompts that produce cited deliverables such as DPIA, threat models and gap analysis
- When to use it
- Useful for compliance, legal and security work where answers must be traceable to fetched source text rather than model memory, such as GDPR, NIS2, DORA, AI Act or CRA questions and CVE/KEV/EPSS lookups.
- Requirements
- A remote MCP client that supports streamable HTTP; connect to the gateway endpoint and complete an OAuth 2.1 flow with dynamic client registration (no API keys). A free tier requires B2B signup in-flow and is limited to 100 searches per day; paid tiers unlock additional corpora and workflows.
Installation
In SourceWeft
- Open Ansvar: US Law in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/eu.ansvar%2Fus-law/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Ansvar Gateway
EU regulatory intelligence over MCP — law, regulations, standards & threat intel, every answer cited or refused.
Ansvar Gateway is a remote MCP server for compliance, legal, and security work. One OAuth connection gives your agent scoped search and get_provision across audited law corpora — Europe-led, with growing North American and APAC coverage; the live, licence-audited jurisdiction list is at ansvar.eu/coverage — plus the EU regulations corpus (GDPR, NIS2, DORA, AI Act, CRA, …), the security-frameworks corpus, and live CVE/KEV/EPSS intelligence.
Every result carries a source citation (_citation: URL, publisher, licence) — answers are cited from fetched text or explicitly refused, never guessed from model memory. Paid tiers add full-fleet fan-out, case law / preparatory works / agency guidance, and structured workflows (DPIA, STRIDE/LINDDUN, gap analysis) that return exportable deliverables.
Connect
Claude Desktop / Claude Code / any MCP client that supports remote servers: add https://gateway.ansvar.eu/mcp as a remote MCP server and complete the OAuth flow. Free-tier signup is in-flow.
What your agent can do
searchlegislation, regulations, standards and threat intel across jurisdictions — results return matching provisions with article-level citations, not paraphrases.get_provision/get_decision— resolve a canonical reference to the exact provision or court decision text.list_coverage— discover what corpora and jurisdictions are live, by domain.- Premium tiers: automatic case-law / preparatory-works fan-out inside
search, agency guidance, and workflow prompts that produce finished, cited deliverables (DPIA, threat model, gap analysis).
Trust properties
- Accuracy over availability: if a source is unreachable, the gateway returns a data-source-unavailable error — it never answers from model memory.
- Per-item attribution: every served row carries source URL, publisher, and licence; content with unresolved licensing is withheld with an explicit notice, not silently dropped.
- EU-hosted (Hetzner, Germany/Finland), no server-side model, no tracking. Operated by Ansvar Systems AB (Sweden, org.nr 559547-2225).
