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.

https://kvasir.legal/mcp

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 They paraphrase amended provisions, cite repealed directives, and cannot say which version an answer relied on.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

JurisdictionStatutesCase law
Germany — federal✅ (federal courts)
Bavaria
North Rhine-Westphalia
Saxony · Brandenburg · Bremen
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 Repealed acts stay in the corpus, flagged as repealed.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

ToolUse it when
resolve_citationyou have a citation string — „§ 573 Abs. 2 BGB", „Art. 6 GDPR"
search_legalyou have a question or topic, not a citation
check_draftyou have a full draft, memo or brief — citations and quoted wording
verify_citationsyou have a bare list of references to check
get_legal_objectyou have a canonical URI
get_legal_objectsyou need several objects at once
get_legal_relationsyou want the citation graph from one node
legal_uri_grammaryou 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.

Licence note: the corpus is served under the terms at kvasir.legal/agb. Search and answer engines are welcome; crawling for model training is not permitted.
