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 Security46
- 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 1 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 enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- 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 Usability76
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 6723 tokens (~103/item across 65 items; 65 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 Management77
- Stability observed for 23 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage90
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 70% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "publish.info" implies "publish" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
- An AI judge read all 66 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the OpenHelvetia Gateway MCP server?
OpenHelvetia Gateway is a hosted endpoint at https://mcp.openhelvetia.swiss/mcp, 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 →

What is the OpenHelvetia Gateway MCP server?
OpenHelvetia Gateway is an MCP server listed in the public MCP registry as swiss.openhelvetia/gateway. Swiss federal law (Fedlex) and political data (LINDAS) for agents, every answer with sources. This page covers its hosted endpoint (https://mcp.openhelvetia.swiss/mcp).
Is the OpenHelvetia Gateway MCP server safe to use?
OpenHelvetia Gateway scores 69 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the OpenHelvetia Gateway MCP server expose?
OpenHelvetia Gateway exposes 65 tools: directory.get, facts.badge, facts.latest, fedlex.check_in_force, fedlex.check_quote, and 60 more. Their descriptions and schemas cost roughly 6,678 tokens of context every time the server is loaded.
Does the OpenHelvetia Gateway MCP server require authentication?
No. We connected to OpenHelvetia Gateway without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the OpenHelvetia Gateway MCP server still maintained?
OpenHelvetia Gateway is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
