Trace EU basis

Today

To verify that a German statute correctly implements an EU directive you open EUR-Lex in a separate tab, find the directive, locate the Umsetzungsgesetz reference, and manually cross-check — a process that can take 20–40 minutes for a single provision.

You ask

What EU directive does § 1 BDSG implement, and which GDPR articles map to it?

Claude

EU basis for § 1 BDSG

§ 1 BDSG implements the GDPR (Regulation (EU) 2016/679), in particular Art. 6 (lawfulness of processing), Art. 9 (special categories), and Art. 88 (processing in the context of employment). German implementing norm: BDSG 2018 (BGBl. I S. 2097). Cross-reference metadata sourced from EUR-Lex.

LLMs are absolutely abysmal at legal research and analysis, and every week we are seeing reports of some lawyer being called out publicly for submitting a brief to a court with hallucinated case citations.

Authentication

Steps

  1. No credentials required

    German Law MCP uses auth_type=none. There is no API key, no OAuth flow, and no environment variable to set. Install the MCP (hosted HTTP or local stdio) and it is ready to use.

  2. Hosted endpoint

    Point your client at https://mcp.ansvar.eu/law-de/mcp. Leave any auth/token field blank. The endpoint is publicly accessible with no rate-limit registration required.

  3. Local (stdio) — first-run database download

    When running via npx @ansvar/german-law-mcp the ~300 MB SQLite database is downloaded on first start. This takes 30–90 seconds on a typical broadband connection. Subsequent starts use the cached database and are fast.

What Claude can do

German Law MCP retrieves and validates primary text — judgment about how to apply that law in a specific matter, and responsibility for any document submitted to a court or authority, remains with the qualified lawyer.

Eight tools covering statute search, provision retrieval, case law, preparatory works, citation validation, legal stance building, citation formatting, and currency checks.

Search statutes by concept or keyword

Full-text search across 6,870 statutes using a three-tier strategy: exact citation match, FTS5 full-text, then LIKE fallback — returns matching provisions with Fundstelle.

Retrieve a specific § by citation

Fetches the verbatim text of a named provision (e.g. § 823 Abs. 1 BGB) directly from the gesetze-im-internet.de corpus.

Search federal court decisions

Searches 5,000 federal decisions from BVerfG, BGH, BVerwG, BAG, BSG, BFH, and BPatG sourced from rechtsprechung-im-internet.de.

Retrieve Bundestag prep works

Returns Drucksachen, Plenarprotokolle, and Beschlussempfehlungen from 89,423 DIP Bundestag records covering WP 19 and WP 20.

Confirm a § reference exists and is in force

Checks whether a cited provision exists verbatim in the indexed corpus and whether it is currently in force — designed to catch hallucinated references before they reach a Schriftsatz.

Assemble a grounded legal argument

Combines statute text, case law, and preparatory works into a structured legal stance — all components drawn from primary sources, not LLM reconstruction.

Format a § reference to citation style

Formats a provision reference into the standard German legal citation style used in Schriftsätze and academic work.

Verify a statute is still in force

Checks the last-amended date and in-force status of a statute against the daily-refreshed database — confirms whether a provision has been superseded or repealed.

Common questions

Will the AI hallucinate § references?

German Law MCP does not generate § references from LLM inference. Every provision returned by search_legislation or get_provision is verbatim text retrieved from the gesetze-im-internet.de corpus using FTS5 full-text search with an exact-citation-match first pass. The validate_citation tool then confirms existence before any § appears in a document. If a provision is not in the 91,843-item index, the tool returns no result rather than a plausible-but-fabricated one.

— HN thread on hallucinated citations in legal filings
Do I still need Juris or BeckOnline?

German Law MCP covers all 6,870 federal statutes and 91,843 provisions from gesetze-im-internet.de, plus 5,000 federal court decisions and 89,423 Bundestag prep works. For everyday German federal law research — retrieving a §, checking currency, tracing EU basis, or validating citations — no paid subscription is needed. Juris and BeckOnline remain useful for proprietary headnotes and editorial commentary, lower-court (Landesgerichte) decisions, and Landesrecht, none of which are in the current corpus.

What about BRAK confidentiality rules and lawyer-client privilege?

The hosted endpoint at mcp.ansvar.eu receives only the query you type — no matter content, document text, or client name is required to retrieve a statute. For matters where privilege is a concern, use the local stdio deployment (npx @ansvar/german-law-mcp): all queries run against a local SQLite database and no data leaves your machine. The ~300 MB database is downloaded once and cached locally.

How complete is the case law coverage?

The current database includes 5,000 federal court decisions from BVerfG, BGH, BVerwG, BAG, BSG, BFH, and BPatG sourced from rechtsprechung-im-internet.de. The total published corpus on that portal is substantially larger; the roadmap lists expanded case law coverage as the next priority. Lower-court decisions (Landesgerichte, Oberlandesgerichte) are not yet included.

— HN thread on case law database economics
Does it cover Landesrecht (state law)?

Not yet. German Law MCP currently covers federal law only — the gesetze-im-internet.de corpus, federal court decisions, and Bundestag legislative materials. Landesrecht (state statutes and state court decisions) is on the public roadmap but not in the current v0.4.0 release.

How fresh is the data?

The database runs automated daily freshness checks against gesetze-im-internet.de. The about tool returns the last-check timestamp and database version so you can confirm the local copy is current. For statutes amended very recently (same-day), there may be a lag of up to 24 hours before the local database reflects the change.
