## 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 2026-10-18.

- **Endpoint Security**: 83/100
  - 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 is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 313 tokens (~156/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 76/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 14% 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 3 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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-18 (score 73, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-16 (score 72, +1)

## MCP tools (2)

### `search_games` (~147 tokens)

Search puzzle games

Search all approved, active catalog games by a literal title, slug or description substring using SQLite case folding (ASCII case-insensitive). Empty query browses the catalog. Optional category and provider are exact catalog filters. Results are canonical, deduplicated per provider/slug, ordered by exact title match then featured/quality/title. Use the returned provider and slug with get_game_details; sourcePage is the onsite play page. No live provider health check is performed.

Input parameters:

- `category` (string)
- `limit` (integer)
- `page` (integer)
- `provider` (string)
- `query` (string): Literal text to find; not a natural-language or semantic search.

Output parameters:

- `items` (array)
- `limit` (integer)
- `nextPage`
- `page` (integer)
- `retrievedAt` (string)
- `source` (string)
- `warnings` (array)

### `get_game_details` (~94 tokens)

Get puzzle game details

Get an approved, active catalog game using provider and slug from search_games. Known URL aliases resolve to the canonical onsite sourcePage, including recovered game URLs. Missing, unapproved, inactive or unplayable catalog records return GAME_NOT_FOUND. Returns stored descriptions and integration capabilities, not invented instructions, provider asset downloads, verified scores or real-time compatibility guarantees.

Input parameters:

- `provider` (string, required)
- `slug` (string, required)

Output parameters:

- `game` (object)
- `retrievedAt` (string)
- `source` (string)
- `warnings` (array)
