Common questions

Is Ansvar: US Law safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.892a470a) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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.

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

search legislation, 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).

About this repository

This is the public home of the hosted Ansvar Gateway — documentation and listing anchor only; the gateway service itself is not developed in this repository. Open-source law-connector code lives across the Ansvar-Systems organization (Apache-2.0).
