Is there an API for BVerwG decisions?

Yes. The REST API and the MCP server return decisions of the Federal Administrative Court with full text and citations. The address https://klaracase.de/mcp/verwaltungsrecht searches only the administrative courts.

Are the administrative courts of the federal states included?

Yes, as far as the states publish their decisions. 110,000+ decisions in this area come from higher administrative courts and administrative courts. The "Courts" table lists the count per court.

What does access cost?

Every call uses credits from your organization's balance, the same one the web app uses. A search costs 1 credit. The table above lists the price per tool. Your first organization receives 30 credits once, valid for 30 days.

How do I connect Claude, ChatGPT or Cursor?

Add the MCP address on this page as a custom connector. Claude and ChatGPT sign in with OAuth. Cursor and your own agents use an API token. The MCP documentation lists the steps for each client.

Are the case numbers in the answers real?

Every case number Klaracase returns points to a decision in the corpus, with court and date. You can fetch and read the full text at any time. The legal assessment stays with you.
