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 Usability74
- 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 972 tokens (~243/item across 4 items; 3 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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 →
score_darts_leg Score darts leg ~279
Use this when the user wants a 501 or 301 darts leg scored: "score my 501 leg", "I threw T20 T20 T20, then S20, then out on D10", "darts scorer, double out". Send each visit to the oche as a turn of up to 3 darts (formats: S20, D16, T19, SB, DB, or 0). Applies standard bust rules (a bust scores nothing and the turn ends; darts after a finish are ignored; double-out requires a double or inner bull to finish unless double_out is false). Returns remaining, per-turn detail, busts, darts thrown, the three-dart average, a checkout suggestion when one exists, and a CSV of the leg. It is not for cricket or around-the-clock variants, and it does not track multi-leg matches — one leg per call.
| Name | Type | Req | Description |
|---|---|---|---|
| double_out | boolean | – | Require a double (or inner bull) to finish, e.g. true for a double-out leg. Default true. |
| start | integer | yes | Leg starting score: 501 (standard) or 301. |
| turns | array | yes | Turns in order; each turn has up to 3 darts. A new entry per visit, e.g. one turn containing T20 and D20. |

score_dice_sheet Score dice sheet ~316
Use this when the user wants a five-dice score sheet scored: "score my sheet, full house [5,5,5,2,2]", "what did I score for chance [3,4,4,5,6]", "tally my dice game". Pass each played category with its 5 dice, and null (or omit) for skipped categories. Returns the category scores, the upper-section total, the 35-point upper bonus when the upper total reaches 63, five-of-a-kind bonuses (100 per repeat after the first 50; provide play_order for chronology, otherwise listed category order is assumed), the grand total, and a CSV of the sheet. It does not choose categories for you and is not for board games — use show_scoreboard for plain point totals.
| Name | Type | Req | Description |
|---|---|---|---|
| play_order | array | – | Played categories in chronological order, e.g. [five_of_a_kind, chance]. Include each played category once. If omitted, assumes the listed category order (ones through chance) for repeat bonuses. |
| sheet | object | yes | Score sheet state: map each category name to the five dice rolled (e.g. [5,5,5,2,2]) if you played that category, or null if you skipped it. Category keys: ones, twos, threes, fours, fives, sixes, th… |

show_scoreboard Show scoreboard ~277
Use this when the user wants a live scoreboard: "keep score for me and Anna", "scoreboard for game night with 4 players", "add 12 points to Anna". Pass mode highest (default), lowest, or target with a positive target score. Scores stay in the open widget only; no online multiplayer. Shows a widget with one row per player, +N/-N buttons (use Smaller step and Bigger step to change the step), undo and history for the last 20 score changes with round numbers, and running totals. Pass the initial player names (2-12); totals start at 0 unless you pass initial scores. Do not use it to score dice sheets or darts legs — use score_dice_sheet or score_darts_leg for those.
| Name | Type | Req | Description |
|---|---|---|---|
| mode | string | – | Win mode, e.g. lowest for a penalty game, highest (default), or target for first to a target score. |
| players | array | yes | Player names in seating order, e.g. ["Anna", "Ben"]. 2-12 players. |
| scores | array | – | Optional starting totals, same order and length as players. Default 0, e.g. [25,0]. |
| target | integer | – | Required target for target mode, e.g. 100. Ignored for highest/lowest modes. |
