kvasir-mcp
MCP server for verifiable German, Austrian, Swiss and EU law. Resolve, search and verify legal citations against the official sources — from any MCP client.
This repository documents the hosted server. There is nothing to install and no local build: point your client at the endpoint below.

Transport: streamable HTTP. Auth: OAuth (most clients discover it automatically)
or an X-API-Key header. A free account with 2,000 monthly units is at
kvasir.legal/signup; reading law on the site needs
no account at all.
Why
Language models answer legal questions from a training snapshot. They paraphrase amended provisions, cite repealed directives, and cannot say which version an answer relied on. This server gives an agent the two operations that fix that: resolve a citation to the wording in force, and verify the citations the agent itself produced.
Coverage
| Jurisdiction | Statutes | Case law |
|---|---|---|
| Germany — federal | ✅ | ✅ (federal courts) |
| Bavaria | ✅ | ✅ |
| North Rhine-Westphalia | ✅ | ✅ |

| Austria | ✅ | ✅ (OGH, VfGH, VwGH) |
| Switzerland | ✅ | — |
| EU | ✅ incl. delegated & implementing acts, Commission guidelines | ✅ (CJEU, General Court) |
~460,000 norms, ~512,000 decisions, ~1.4 million typed citation edges. Sources are
checked daily (weekly for Saxony and Bremen). Repealed acts stay in the corpus,
flagged as repealed. Live counts and per-source timestamps:
/api/v1/status.
Tools
| Tool | Use it when |
|---|---|
resolve_citation | you have a citation string — „§ 573 Abs. 2 BGB", „Art. 6 GDPR" |
search_legal | you have a question or topic, not a citation |
check_draft | you have a full draft, memo or brief — citations and quoted wording |
verify_citations | you have a bare list of references to check |
get_legal_object | you have a canonical URI |
get_legal_objects | you need several objects at once |
get_legal_relations | you want the citation graph from one node |
legal_uri_grammar | you want to build URIs yourself |
Arguments, limits and response shapes: kvasir.legal/developers/mcp-tools.
Example
Ask your agent: „Which decisions cite Art. 6 GDPR?" — it calls
get_legal_relations on norm:eu:GDPR:art_6 and gets the citing decisions with
court, docket number and canonical URI, ordered by authority.
Or without any client:
curl -s "https://kvasir.legal/api/v1/relations/norm:eu:GDPR:art_6?direction=in&limit=5"
Honest limits
- Verification is a fact about this corpus. A miss means „not found here" — a typo or a coverage gap — not „this citation is fake".
- A citation can exist, be current, be quoted correctly, and still be the wrong authority for the question. This is not legal advice.
- Commission guidelines are interpretive, not binding law, and are labelled as such.
- No case law yet for Switzerland, Saxony, Brandenburg and Bremen.
