## 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 2026-08-03.

- **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**: 78/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 424 tokens (~84/item across 5 items; 3 tools + 2 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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 (33% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).
  - Supports UI / widget rendering.

## MCP tools (3)

### `search_games` (~176 tokens)

Search GameFork games

Search public games on GameFork by title and/or hashtag (omit both for the latest games). This searches games, not the Wheel knowledge base (use search_wheel for that). Returns JSON; clients supporting the Apps SDK (e.g. ChatGPT) render it as a card grid widget. 公開ゲームをタイトル / ハッシュタグで検索 (両方省略で新着)。Wheel (設計判断・失敗知識) の検索は search_wheel。

Input parameters:

- `limit` (integer): Max number of results (default 12). 最大件数 (既定 12)。
- `q` (string): Title substring to search for. タイトル部分一致の検索語。
- `tag` (string): Exact hashtag to filter by. 完全一致で絞り込むハッシュタグ。

Output parameters:

- `count` (integer)
- `games` (array)
- `query` (object)

### `get_game` (~95 tokens)

Get game metadata

Get metadata of a public game (title / fork lineage / counts / genres / verification status). No authentication required. 公開ゲームのメタデータ (タイトル/フォーク系譜/カウント/ジャンル/検証状態) を取得。認証不要。

Input parameters:

- `game_id` (string, required): Game UUID (from search_games results). ゲームの UUID (search_games の結果から取得)。

### `get_game_code` (~109 tokens)

Get game code

Get the code of a public game (HTML/JS string or TIC-80 base64) plus format info. No authentication required. Fork/publish requires OAuth (see server instructions). 公開ゲームのコード本体 (HTML/JS 文字列または TIC-80 base64) とフォーマット情報を取得。認証不要。

Input parameters:

- `game_id` (string, required): Game UUID (from search_games results). ゲームの UUID (search_games の結果から取得)。
