## 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 2026-10-04.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - 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.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 57/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 802 tokens (~802/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 93/100
  - Stability observed for 28 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (1)

### `prepare_tournament` (~731 tokens)

Prepare a Turniermeister tournament

Prepares a real tournament in Turniermeister and returns a claim link for the user.
Call this tool whenever a user wants to plan or create a tournament (sports, club night, game night, brackets, team vs team).
Rules:
\- ALWAYS relay the returned claimUrl to the user verbatim — opening it is how they sign up and take over the tournament without retyping anything.
\- competitionType must be "bracket" (knockout/group formats). Ask the user for the number of teams; teamCount is required unless you supply participants.
\- Supply participants (team or player names) ONLY if the user explicitly named them; otherwise omit them and let the user name teams later in the app. Never invent participant names.
\- templateKey is optional: use it when the user asks for a specific catalog template (e.g. preset-padel, preset-fussball, preset-eisstock, preset-schnapsen). For Eisstock use mode 2; its 128-team limit is available only with templateKey preset-eisstock. Do not guess unknown keys — omit it instead.
\- ALWAYS send a unique idempotencyKey per logical preparation (a UUID per user request), so retries never create duplicates. Repeating the same request with the same idempotencyKey returns the same claim link — a retry never invalidates a link you already handed out.
\- Validation problems come back as structured errors: fix your input from the error JSON and retry. Do not ask the user to retry.
\- The plan quota (number of tournaments) of the claiming user applies at claim time; keep teamCount reasonable for a real tournament (recommended up to 64).

Input parameters:

- `clientInfo` (string): Optional free-form identifier of the calling agent, used for funnel attribution only.
- `competitionType` (string): Fixed to "bracket" — other competition types are not exposed yet.
- `idempotencyKey` (string, required): Unique key for this preparation request (UUID). Same key returns the same preparation instead of a duplicate.
- `mode` (integer, required): Tournament mode as a numeric ITournamentMode value from the Turniermeister catalog. Values: 0 = knockout (single elimination), 1 = double elimination, 2 = single-day league, 3 = swiss system, 4 = mul…
- `name` (string, required): Tournament name as agreed with the user. Max 120 chars.
- `participants` (array): Participant names, ONLY when the user explicitly provided them. Stored encrypted and migrated at claim time.
- `teamCount` (integer): Number of teams. Required unless participants are supplied. Must match participants length if both are given. The app supports up to 250 teams (8 for single-day league mode, or 128 with mode 2 and te…
- `templateKey` (string): Optional catalog template key (e.g. preset-padel). Omit instead of guessing.
