概览

AI 生成的概览

托管式 MCP 服务器,让助手依据官方来源解析、检索并核验德国、奥地利、瑞士及欧盟法律引注,并附带出处。

可以做什么
将引注字符串解析为现行有效文本,或按问题或主题检索德国、奥地利、瑞士及欧盟的法条与判例。检查完整草稿或备忘录中的引注与引用原文,或核验一份纯引注清单。按规范 URI 获取单个或多个法律对象,并从某一节点遍历引注关系图。查询 URI 语法规则,自行构建规范标识符。
适用场景
当助手回答德国、奥地利、瑞士或欧盟法律问题,需要现行文本、版本出处,或需要核对自己生成的引注与引文是否真实且归属正确时适用。
运行要求
远程 streamable HTTP 端点,无需安装。通过 OAuth 登录(多数客户端可自动发现),或使用免费账户提供的 X-API-Key 请求头,账户有每月额度。需要网络访问。
安装前请注意
核验结果仅反映该语料库:未命中可能是拼写错误或覆盖缺口,并不证明引注是伪造的。引注即使存在且引用正确,也可能并非该问题的正确依据,且本服务不构成法律意见。瑞士、萨克森、勃兰登堡和不来梅暂无判例。条款不允许为模型训练而抓取内容。

README

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 They paraphrase amended provisions, cite repealed directives, and cannot say which version an answer relied on.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 Repealed acts stay in the corpus, flagged as repealed.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:

bash
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.

Links

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.
