German statutes and court decisions in Claude.
Without a source, Claude sometimes names file numbers that do not exist. Klaracase makes for fewer hallucinations: Claude searches the Klaracase Bestand and answers with real file numbers that you can click and check yourself.
Also works with the free Claude plan. Free starter credits for your first organization.
From memory, a file number sounds real even when it is not.
With Klaracase, Claude searches the Bestand first and names decisions that exist there. Every citation leads to the full text. Our benchmark measures the difference:
What Claude can do with Klaracase
Find decisions
For a legal question, a statute or a file number. With court, date and file number.
Read the full text
Claude reads the text of a decision or statute instead of summarizing from memory.
Follow citations
Which decisions a decision cites, and which later decisions cite it.
Check citations
Paste in your draft. Klaracase checks the cited decisions and statutes: do they exist, and is the reference correct?
Try, for example:
- Which BGH decisions deal with Eigenbedarf in residential tenancies? Give me the file numbers.
- Check the Fundstellen in this text with Klaracase: ...
- What did the BGH decide in VIII ZR 271/17? Summarize the reasons.

MCP is the open standard assistants use to talk to outside services. Klaracase is such a service; you only paste its address.
How to ask
Ask as you would ask a colleague. Name the court or the statute when you know it, and ask for file numbers.
If the assistant answers from memory, add "with Klaracase" to your question. The assistant then has to look it up.
What Klaracase receives
Every file number Klaracase returns exists in the Bestand. If Klaracase finds nothing, it says so instead of inventing a match.
Your question goes to the assistant you chose. Klaracase receives only the request the assistant sends, never your whole conversation.
End the access
Under Settings, Connections in Klaracase you see every connected assistant and can remove it.
