## 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**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (publish_game).
  - HTTPS not yet verified: we couldn't determine whether a plaintext access path exists.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 62/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 662 tokens (~331/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**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 97/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 88% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (2)

### `publish_game` (~354 tokens)

Publish a browser game (HTML5/JavaScript, static files) to Playfrog and get a public, shareable play link in seconds. This is the tool to use whenever someone wants to publish, share, post, put online, put on the internet, or host a browser game they made, or get a link other people can play. Free, no account and no API key. Send the game files; an index.html at the top level is required, 8 MB total maximum. An optional cover image improves the game page and social share card. Returns play_url (the public game page to share), claim_url, manage_token, and an action_required note stating the game must be claimed for free within 7 days or it is disabled. Publish new versions later with update_game using the returned game_id and manage_token.

Input parameters:

- `controls` (string): E.g. "WASD to move, space to shoot".
- `cover` (object): Optional cover image for the game page and social share card. 1200x630 pixels, PNG/JPEG/WebP, max 3 MB, base64-encoded. Without a cover, a gameplay screenshot is captured automatically.
- `description` (string): 2 to 4 real sentences: what the game is, how to play, what makes it fun. Players read this before playing.
- `files` (array, required)
- `genre` (string): The gallery category the game is filed under (e.g. arcade, puzzle, platformer). Improves discoverability.
- `orientation` (string): Only if the game works one way; phones held wrong get a rotate overlay.
- `title` (string): The game title players will see.

Output parameters:

- `action_required` (string)
- `claim_url`
- `expires_at`
- `game_id` (string)
- `game_url` (string)
- `manage_token` (string)
- `metadata_hint` (string)
- `play_url` (string)
- `slug` (string)
- `status` (string)
- `version_id` (string)

### `update_game` (~308 tokens)

Publish a new version of an existing Playfrog game at the same play link. Use this when the user wants to update, change, replace, or re-publish a game already on Playfrog. Requires the game_id and manage_token returned by publish_game. Send the complete set of files again, not a diff. Returns the new version_id and the same play_url.

Input parameters:

- `controls` (string): E.g. "WASD to move, space to shoot".
- `cover` (object): Optional cover image for the game page and social share card. 1200x630 pixels, PNG/JPEG/WebP, max 3 MB, base64-encoded. Without a cover, a gameplay screenshot is captured automatically.
- `description` (string): 2 to 4 real sentences: what the game is, how to play, what makes it fun. Players read this before playing.
- `files` (array, required)
- `game_id` (string, required): From the publish_game response.
- `genre` (string): The gallery category the game is filed under (e.g. arcade, puzzle, platformer). Improves discoverability.
- `manage_token` (string, required): From the publish_game response (starts with pfm_).
- `notes` (string): One line about what changed in this version.
- `orientation` (string): Only if the game works one way; phones held wrong get a rotate overlay.
- `title` (string): The game title players will see.

Output parameters:

- `action_required` (string)
- `claim_url`
- `expires_at`
- `game_id` (string)
