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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability75
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

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 →
generate_word_puzzle Generate word puzzle ~321
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |

show_word_puzzle Show word puzzle ~136
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |
