Available tools 4

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

amendments

list_amendments

List consolidation version dates for a Swiss federal act. Returns the dates each consolidated version took effect.

article

get_article

Retrieve a single article when you already know the EXACT article number (e.g. from a cross-reference). Do NOT call this tool repeatedly to search for provisions — use get_law_text instead to fetch the full act or a section and locate relevant articles in the text.

law

get_law_text

Retrieve the official consolidated text of a Swiss federal act (or a specific title/chapter) directly from Fedlex (fedlex.admin.ch). This is the PRIMARY tool for answering Swiss law questions — always start here. Fetch the full act or a specific section, then locate relevant provisions in the returned text. Prefer this over get_article unless you already know the exact article number.

title

search_by_title

Search Swiss federal legislation titles in the Classified Compilation (RS/SR) on Fedlex. Use to find the RS number of a law when you know its name but not its number. Searches titles only, not article content. Returns only acts currently in force.

Fedlex Connector — questions

Answers built from our own checks of this server.

What can Fedlex Connector do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_article, get_law_text, list_amendments, search_by_title. 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 →

Is Fedlex Connector 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 370 ms. The bar chart above shows every period we have measured.

How do I connect Fedlex Connector?

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

Does Fedlex Connector need an API key?

No. Fedlex Connector completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Fedlex Connector?

It answers our handshake in 370 ms on average, which is faster than 38% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Fedlex Connector open source?

Yes — it is published under the MIT licence, written in TypeScript and 6 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
