Endpoint Security57
Transport & Reachability100
Schema Quality & AI Usability80
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 519 tokens (~129/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the Fedlex Connector MCP server?

Fedlex Connector is a hosted endpoint at https://mcp.fedlex-connector.ch/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 4 exposed · ~519 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_article ~153

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.

NameTypeReqDescription
articlestringyesArticle number (e.g. '3', '28a', '41')
datestringConsolidation date in YYYY-MM-DD format. Defaults to the latest available version.
languagestringLanguage (default: de)
rs_numberstringyesRS/SR number (e.g. '210' for CC, '220' for CO, '311.0' for CP)

No output schema declared.

No examples provided.

get_law_text ~188

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.

NameTypeReqDescription
languagestringLanguage (default: de)
pagenumberPage number for paginated results (default: 1). Large acts are split across multiple pages.
rs_numberstringyesRS/SR number (e.g. '210' for CC, '220' for CO)
sectionstringLimit to a specific title, chapter, or part (e.g. 'Titre huitième', 'Zweiter Teil'). If omitted, returns the full act.

No output schema declared.

No examples provided.

list_amendments ~77

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

NameTypeReqDescription
languagestringLanguage for amendment titles (default: de)
rs_numberstringyesRS/SR number
sincestringStart date in YYYY-MM-DD format (default: 1 year ago)

No output schema declared.

No examples provided.

search_by_title ~101

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.

NameTypeReqDescription
languagestringLanguage for results (default: de)

No output schema declared.
