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。

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 They paraphrase amended provisions, cite repealed directives, and cannot say which version an answer relied on.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 Repealed acts stay in the corpus,
flagged as repealed.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