MCP server for Swiss federal legislation via Fedlex (native ELI), verifiable citations.
If you already use Ch, the ch mcp server is the piece that lets your assistant work with it directly. MCP server for Swiss federal legislation via Fedlex (native ELI), verifiable citations.
MCP server for Swiss federal legislation via Fedlex, the Federal Chancellery's official publication platform. Fedlex is genuinely ELI-native (European Legislation Identifier) even though Switzerland is not an EU member. Multilingual: German, French, Italian, English.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
ch_search_acts — Full-text search over act titles, in one of four languagesch_get_act — Full detail for one act by its Fedlex ELI URIConfiguration is passed through the environment: CH_ELI_BASE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
The server ships on PyPI as ch-eli-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Ch's toolset — ch_search_acts, ch_get_act — is a fair guide to whether it matches your workflow. It is maintained by matematicsolutions; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Ch's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
