## 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 2026-10-23.

- **Endpoint Security**: 80/100
  - 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.
  - 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**: 68/100
  - 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 1968 tokens (~656/item across 3 items; 2 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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.
  - 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 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.
  - Supports UI / widget rendering.

### `generate_tournament_bracket` (~946 tokens)

Generate tournament bracket

Use this when the user wants a tournament bracket or schedule (tournament bracket maker, bracket generator, single elimination or double elimination bracket, round robin schedule generator, Swiss pairings, a bracket for 6, 10 or 12 teams with byes). Builds the full structure for 2-128 players or teams: standard seeding so top seeds meet last, byes for the top seeds when the field is not a power of two, optional third-place match, grand final reset, round robin via the circle method with balanced home/away, Swiss round 1, optional timetable over several courts, a printable PDF bracket and a CSV schedule. Results already known can be included to advance winners. Does not predict winners, fill in picks for famous tournaments, or schedule leagues with venue or travel constraints.

Input parameters:

- `break_minutes` (number): Changeover time between matches on a court, in minutes (0-120, default 0). Example: 5
- `courts` (number): Courts, tables, boards or fields available at the same time (1-64), used for the timetable. Example: 3
- `draw_points` (number): Points for a draw (default 1 for round robin, 0.5 for Swiss). Example: 1
- `format` (string, required): Tournament format: single_elimination (knockout), double_elimination (out after two losses, losers bracket, grand final), round_robin (everyone plays everyone once; league), swiss (fixed number of ro…
- `grand_final_reset` (boolean): Double elimination only (default true): if the losers-bracket champion wins the grand final, a second deciding match is played, so nobody is out after one loss. Example: false
- `loss_points` (number): Points for a loss (default 0). Example: 0
- `match_minutes` (number): Length of one match in minutes (5-600). Giving this adds start times and courts to every match. Example: 20
- `meetings` (number): Round robin only: 1 (default) = every pair meets once; 2 = home and away (double round robin). Example: 2
- `paper` (string): Paper size for the landscape PDF: letter (default) or a4. Example: a4
- `participant_count` (number): Use instead of participants when the user gives only a number: makes Team 1 ... Team N (2-128). Example: 12
- `participants` (array): Players or teams, 2-128 unique names. With standard seeding the order is the ranking: first = seed 1. Example: ["Ann","Bob","Cy","Dee","Eve","Finn"]
- `random_seed` (number): Draw number for random seeding (1-999999). The same participants and number always give the same draw. Example: 4821
- `results` (array): Results already played, in any order for elimination formats and round by round for Swiss. Each needs the players (p1, p2) or a match id, plus a winner or both scores. Example: [{"p1":"Ann","p2":"Fin…
- `seeding` (string): standard (default): list order is the seed ranking, 1 plays the lowest seed, top seeds get the byes and seeds 1 and 2 can only meet in the final. random: a reproducible random draw (see random_seed),…
- `start_time` (string): Start time of the first matches, 24-hour HH:MM (default 09:00). Example: "18:30"
- `swiss_rounds` (number): Swiss only: number of rounds (default log2 of the field, rounded up; maximum depends on the field size). Example: 5
- `third_place_match` (boolean): Single elimination only: add a third-place match between the semifinal losers. Example: true
- `title` (string): Tournament name for the bracket, PDF and CSV. Example: "Friday Ping Pong Cup"
- `win_points` (number): Round robin / Swiss table points for a win (default 3 for round robin, 1 for Swiss). Example: 2

Output parameters:

- `bracket_size` (number|null)
- `byes` (array)

### `calculate_bracket_standings` (~902 tokens)

Calculate bracket standings

Use this when the user reports results of a tournament made with generate_tournament_bracket (or describes one) and wants the updated bracket, who advances, the standings table or what is next. Takes the same format and participants plus every result so far (winner or scores per match) and returns the advanced bracket, the round robin or Swiss table (points, head-to-head, score difference; Buchholz for Swiss), final places, the next Swiss round's pairings, and the next matches to play. Do not use to predict outcomes; it only records results the user gives.

Input parameters:

- `break_minutes` (number): Changeover time between matches on a court, in minutes (0-120, default 0). Example: 5
- `courts` (number): Courts, tables, boards or fields available at the same time (1-64), used for the timetable. Example: 3
