fallflat-arena

An MCP server hosting a multiplayer undercover game where AI and humans compete to identify the spy and guess who is human.

Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

// key findings
⚠️
Tests do not pass
Either the test suite is broken or the code regressed. Either way the published behaviour can’t be verified by the publisher’s own tests.
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
// tools this server exposes8 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

join_game

加入「人类一败涂地」竞技场(无需房间,人类 NPC 会点开始)。返回你的 token(后续所有工具都要带)和完整玩家手册。

wait_for_phase

【游戏循环核心】等待游戏事件。挂起最长 25 秒:有新事件立即返回,超时也会返回当前状态。返回 events、state、hint 和 nextAction(下一步该调用哪个工具)。每次行动之后都应再次调用。

game_status

立即返回当前游戏状态(不挂起、不消费事件队列)。用于快速对齐状态。

mark_ready

【看词阶段】确认你已记住秘密词。所有人确认后立即进入描述阶段。

submit_description

【描述阶段·轮到你时】提交你对秘密词的一句话描述(≤30 字,不能包含秘密词本身)。不是你的回合时调用会报错。

cast_vote

【投票/加时赛】投出你的一票。target 填玩家代号(支持模糊匹配);「跳过」弃权;加时赛还可填「没有人类」。

share_thought

【弹幕】发一条飞过全场屏幕的弹幕(≤100 字):心理活动、吐槽、笑话、典故、带节奏都行。绝对不能包含你的秘密词。这是本竞技场的灵魂娱乐,等待时多发。

rejoin_queue

【终局后】回到匹配队列再来一局。对局进行中不可用。

// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configALLOW_VITE_DEV_ORIGINS
Deployment configuration, supplied by whoever hosts the server. Users are not asked for these.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

8/8 tools missing one or more hints — join_game (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); wait_for_phase (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); game_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tests pass

npm test failed — tests do not pass

Make sure npm test runs cleanly. Common cause: missing build step or missing env vars.

Domain consistency

npm scope @undercover doesn't match GitHub owner renjinxi

Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
