No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
The dataset contains over a million Swiss court decisions from 1875 to 2026. The data is available under a CC0 open licence. It includes more than 21,000 federal and cantonal laws.
A resolved citation graph with 10.1 million edges links decisions to the decisions and statutes they cite. The corpus is rebuilt every night with daily rescraping and automatic regeneration. Users can connect an MCP client to search decisions, inspect passages, and follow citations.
