## 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**: 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**: 62/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 587 tokens (~195/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 69% 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

First indexed and scored.

## MCP tools (3)

### `search_games` (~296 tokens)

Use this to find games for a group when you don't have a specific game in mind ("3 friends, one on PS5 and one on Xbox"). Searches CoopGames' catalog of co-op and multiplayer games (PC, PS5, PS4, Xbox, Switch, Switch 2). All filters are optional and combine with AND. With several platforms it returns only games with crossplay between all of them. Returns up to 10 games, most popular first, with the total that match; each has its CoopGames page url, platforms, online and same-screen player counts, crossplay and price. For one known game use get_game instead. Read-only.

Input parameters:

- `crossplay` (boolean): Only games with crossplay
- `free` (boolean): Only free-to-play
- `genre` (string): shooter, estrategia_moba, supervivencia, sandbox, party, rpg_mmo, terror, aventura_puzzles, peleas, deportes_carreras
- `how` (string): 'local' = same screen / couch
- `limit` (integer): Default 5
- `mode` (string)
- `one_copy` (boolean): Only games where one copy is enough for the whole group
- `platforms` (array): Platforms the group has. 'xbox' is Xbox One and Series; 'switch2' is Switch 2
- `players` (integer): How many people play together

### `get_game` (~129 tokens)

Use this when the user names a specific game and wants the full multiplayer picture: platforms, online and same-screen player counts, crossplay for every pair of its platforms, session length, whether one copy is enough for the group, and the link to its CoopGames page. Accepts the game name or slug. If the name is ambiguous or unknown it returns an error with up to 5 suggestions to retry with. For a single yes/no between two platforms, crossplay_check is lighter. Read-only.

Input parameters:

- `name` (string, required): Game name or slug, e.g. 'It Takes Two'

### `crossplay_check` (~126 tokens)

Use this for a quick yes/no: can players on two different platforms play this game together online? Returns crossplay true or false plus the game page url. Returns false with a reason if the game is not on both platforms. PS4 with PS5, Xbox One with Series and Switch with Switch 2 count as the same family, not crossplay. platform_a and platform_b must differ. For the full matrix of a game use get_game. Read-only.

Input parameters:

- `game` (string, required)
- `platform_a` (string, required)
- `platform_b` (string, required)
