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.

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.

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.
