The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

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.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Zefix MCP's toolset — name_or_uid, language_key, cantons and 10 more — is a fair guide to whether it matches your workflow. It is maintained by zahhar; worth a glance at recent repository activity before you build anything load-bearing on it.
