Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
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
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.

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 →
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.
| Name | Type | Req | Description |
|---|---|---|---|
| article | string | yes | Article number (e.g. '3', '28a', '41') |
| date | string | – | Consolidation date in YYYY-MM-DD format. Defaults to the latest available version. |
| language | string | – | Language (default: de) |
| rs_number | string | yes | RS/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.
| Name | Type | Req | Description |
|---|---|---|---|
| language | string | – | Language (default: de) |
| page | number | – | Page number for paginated results (default: 1). Large acts are split across multiple pages. |
| rs_number | string | yes | RS/SR number (e.g. '210' for CC, '220' for CO) |
| section | string | – | Limit 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.
| Name | Type | Req | Description |
|---|---|---|---|
| language | string | – | Language for amendment titles (default: de) |
| rs_number | string | yes | RS/SR number |
| since | string | – | Start 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.
| Name | Type | Req | Description |
|---|---|---|---|
| language | string | – | Language for results (default: de) |
| query | string | yes | Keywords to match against act titles (e.g. 'code civil', 'protection des données') |
No output schema declared.
No examples provided.
