## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 77/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 80/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1429 tokens (~119/item across 12 items; 10 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

Input parameters:

- `id` (string, required)

### `list_pages` (~60 tokens)

Seiten auflisten

Listet alle Seiten von was-ist-mcp.ch auf, mit Kürzel, Titel, Link und einer kurzen Beschreibung. Der gute erste Aufruf, bevor Sie gezielt eine Seite holen. (Lists every published page of the site with its slug and description.)

### `get_page` (~104 tokens)

### `list_mcp_services` (~90 tokens)

### `explain_this_connection` (~92 tokens)

Diese Verbindung erklären

Berichtet auf Deutsch, was beim Verbinden zwischen Ihrem KI-Programm und diesem Server geschehen ist: auf welche Fassung von MCP sich beide geeinigt haben, wie Ihr Programm heisst und was es über sich angemeldet hat. Diese Angaben stehen nirgends auf der Seite. Sie entstehen erst in dem Moment, in dem Ihr Programm sich verbindet. (Reports what this very connection negotiated, in German.)

### `server_info` (~48 tokens)
