## 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 2026-11-05.

- **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 4 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**: 65/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 655 tokens (~163/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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 (4)

### `pool_term` (~205 tokens)

What does a pool, billiards or snooker word mean? 36 terms and 27 names of games in the family, one line each - screw, stun, throw, half-ball, snooker, bank, kick, carom, jaws, rattle, scratch, shape, run out, and what separates pool from snooker from carom. One argument: the word itself, one word or short phrase, any case. A whole sentence will match on the explanation or not at all, so pull the word out first. Omit q to get all of them. found:false means THIS SITE has no line about it - it does not mean the term does not exist, and you must not supply a definition of your own in its place.

Input parameters:

- `kind` (string): terms = the 36 playing terms; names = the 27 games in the family; both = search each.
- `q` (string): One word or short phrase. Example: screw

### `pool_rules` (~121 tokens)

How is eight-ball played? The seven rules this game enforces: the break from behind the head string, the open table until the first called pot, calling the ball and the pocket, what counts as a foul, ball in hand anywhere as the penalty, the eight last and only in the called pocket, and what loses the frame. No arguments. THESE ARE THIS GAME'S RULES - WPA eight-ball as the simulation applies it, not the full WPA rule book. For a tournament question cite https://wpapool.com/rules-of-play/ alongside.

### `pool_player` (~189 tokens)

Who are the great pool, snooker and carom players, and what is each one known for? 45 players, each with the method they are known for. Filter by part of a name (q), by country as commonly listed, or by ONE lower-case game tag; combine them, or send nothing for all 45. The game tag has exactly one spelling each: eight-ball, nine-ball, ten-ball, rotation, one-pocket, straight pool, snooker, three-cushion carom, money games - '9-ball' and 'Nine-ball' will miss. The order is editorial and is NOT a ranking; do not present a position as a standing.

Input parameters:

- `country` (string): As commonly listed. Example: Philippines
- `game` (string): One lower-case tag from the list.
- `q` (string): Part of a name. Example: Reyes

### `pool_search` (~100 tokens)

The word could be a term, a game name, a rule, a player or a feature and you do not know which: search every collection in one call. Each hit says which collection it came from and how it matched (exact, key or body). Use this instead of guessing which of the other tools to call. One required argument.

Input parameters:

- `limit` (integer)
- `q` (string, required): One word or short phrase. Example: bank
