## 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**: 75/100
  - 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 553 tokens (~184/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_word_puzzle` (~321 tokens)

Generate word puzzle

Use this when the user wants to make a custom word-guessing game (a 'make your own' five-letter word puzzle) to send to a friend, partner, class, or team: from a secret word they choose (4-8 letters, names allowed) or a random common five-letter word. Optional title and a secret message revealed when solved. Returns a share link anyone can play in a browser and shows the playable puzzle in the widget. The answer and secret message are not included in the reply to you. Does not make crosswords, word searches, or anagram solutions, and does not solve other puzzles.

Input parameters:

- `allow_any_guess` (boolean|null): If true, any letter combination counts as a guess. Default false: guesses must be real English words (the secret word itself is always accepted). Example: true for casual play or non-English words.
- `answer`: The secret word the friend must guess, 4-8 letters A-Z, e.g. PIZZA. Names are fine even if not in the dictionary (e.g. MAYA). Leave it out to use a random common 5-letter word that nobody in the chat…
- `message`: Secret message revealed only after the word is guessed (or all 6 guesses are used), up to 200 characters, e.g. "Happy anniversary! Dinner is at 8."
- `title`: Puzzle title shown above the grid, up to 60 characters, e.g. "Guess our date night". Must not contain the answer.

Output parameters:

- `downloads` (object)
- `guess_rule` (string)
- `has_secret_message` (boolean)
- `letters` (number)
- `max_guesses` (number)
- `note` (string)
- `share_url` (string)
- `source` (string)
- `title` (string)

### `show_word_puzzle` (~136 tokens)

Show word puzzle

Use this when the user wants to play a word-guessing puzzle in the chat: either a puzzle share link someone sent them (made with this app), or a random common five-letter word ('unlimited' practice). Shows a playable grid with six guesses; the answer is not included in the reply to you. Does not open puzzles from other websites and does not reveal answers or give hints.

Input parameters:

- `puzzle_link`: A puzzle share link made by this app, e.g. https://word-guess.zovo.one/dl/play/s.AbC123... Leave it out to play a random common 5-letter word.

Output parameters:

- `downloads` (object)
- `guess_rule` (string)
- `has_secret_message` (boolean)
- `letters` (number)
- `max_guesses` (number)
- `note` (string)
- `share_url` (string)
- `source` (string)
- `title` (string)
