OpenHelvetia Gateway missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 65

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

OpenHelvetia Gateway — questions

Answers built from our own checks of this server.

What can OpenHelvetia Gateway do?

It exposes 65 tools, read directly from the server on our last check. Among them: directory.get, facts.badge, facts.latest, fedlex.check_in_force, fedlex.check_quote, fedlex.cite and 59 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is OpenHelvetia Gateway mostly used for?

Its tools cluster around fedlex, i14y and lindas. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is OpenHelvetia Gateway working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 253 ms. The bar chart above shows every period we have measured.

How do I connect OpenHelvetia Gateway?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does OpenHelvetia Gateway need an API key?

No. OpenHelvetia Gateway completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 65 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is OpenHelvetia Gateway?

It answers our handshake in 253 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
