概覽
託管式 MCP 伺服器,讓助理依據官方來源解析、檢索並核驗德國、奧地利、瑞士及歐盟法律引註,並附出處。
- 可以做什麼
- 將引註字串解析為現行有效條文,或依問題或主題檢索德國、奧地利、瑞士及歐盟的法規與裁判。檢查完整草稿或備忘錄中的引註與引用原文,或核驗一份純引註清單。依標準 URI 取得單一或多個法律物件,並從某一節點遍歷引註關係圖。查詢 URI 語法規則,自行建構標準識別碼。
- 適用情境
- 當助理回答德國、奧地利、瑞士或歐盟法律問題,需要現行條文、版本出處,或需要核對自己產生的引註與引文是否真實且歸屬正確時適用。
- 執行需求
- 遠端 streamable HTTP 端點,無需安裝。透過 OAuth 登入(多數用戶端可自動探索),或使用免費帳號提供的 X-API-Key 標頭,帳號有每月額度。需要網路連線。
安裝

Web executable,透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。
交給代理程式安裝
把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式,或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南,先向你展示發布者、端點和登入方式,經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/legal.kvasir%2Fkvasir-legal/install.md,並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前,先告訴我它的發布者、端點和登入方式,等我確認。不要把 API 金鑰寫進命令或我會提交的檔案;問我金鑰應從哪裡取得。其他 MCP 客戶端
把它新增到你客戶端的 mcpServers 設定中。 客戶端會在首次連接時完成 OAuth 登入。

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 They paraphrase amended provisions, cite repealed directives, and cannot say which version an answer relied on.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 Repealed acts stay in the corpus,
flagged as repealed.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