Overview

Description from the maker (original English)

Read-only tools to inspect your agent setup: list MCP servers, flag unpinned ones, test a policy.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 0 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "ratchet": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/suhui-organization/ratchet:v0.12.1"
      ]
    }
  }
}

Run this in your terminal

claude mcp add ratchet -- docker run -i --rm ghcr.io/suhui-organization/ratchet:v0.12.1

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "ratchet": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/suhui-organization/ratchet:v0.12.1"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "ratchet": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/suhui-organization/ratchet:v0.12.1"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Basic checksi

We check information anyone can see; we have not read the code. Checks that do not apply are left out of the count. · Checked Nov 7, 2026

  • ! Caution

    Maker matches the repo

    The publisher (iversonwuwei) is not the repo owner (suhui-organization); someone else may have listed it

  • … Not checked yet

    Still maintained

    We have not read this repo from GitHub yet

  • … Not checked yet

    Has a licence

    We have not read this repo from GitHub yet

  • – Not applicable

    Endpoint responds

    This one runs on your computer; there is no internet endpoint

  • – Not applicable

    Sign-in with OAuth

    Runs on your computer and uses local settings instead

  • … Not checked yet

    No hidden instructions in tool descriptions

    Runs on your computer; we can only read tool lists from internet endpoints

Compared with others in Otheri

  • More stars than 0% of the other 32712 servers in this category
  • Published to the registry more recently than 45% of the other 32712 servers in this category
  • Basic checks equal to or better than 27% of the other 32712 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Ratchet safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.12.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

Ratchet

从 agent 的真实行为编译最小权限策略,并给出收货方能自己验证的证据。

curl -fsSL https://github.com/suhui-organization/ratchet/releases/latest/download/install.sh | sh

macOS / Linux 上也可以用 Homebrew(formula 钉住每个平台的 sha256):

brew install suhui-organization/tap/ratchet

Claude Desktop 用户可以直接装本地 server(一键安装包,不需要命令行):

下载 ratchet-0.12.0.mcpb 并打开它,Claude Desktop 会完成安装。包内是四个平台的原生二进制 + 一份 manifest.json (MCPB 规范),不需要 Node 或 Python 运行时。

Linux / macOS(amd64 · arm64)。装完先跑这一条——只读配置,不执行任何东西:

ratchet scan --home ~

它会在十秒内告诉你:这台机器上有几个 MCP server,其中几个没锁版本。 (我自己的机器:16 个里 12 个没锁。)

棘轮只能往一个方向转:权限可以收紧,放宽必须显式。

这是什么

一个跑在你自己机器上的工具:它读 agent 用到的工具清单, 编译出一份最小权限策略,再把这次审计的产物打成一份 收货方不需要信任你、也不需要装任何东西就能验证的交付目录。

这不是什么

  • 不是沙箱、不是容器运行时;
  • 不是 prompt 内容过滤器;
  • 不是企业控制台(不做 dashboard、不做多租户、不做 SaaS 依赖);
  • 不要求你把日志传到哪里去。

为什么值得存在

市场上的产品要么让你自己手写策略(Cedar / CEL / 自然语言), 要么要你相信它的日志。Ratchet 做的是这两件之间缺失的一步: 策略由观测编译,证据由收货方自己算哈希。

一个例子

# 1) 编译:从工具清单得到一份保守的最小权限策略

ratchet policy draft --from examples/inventory.json --out policy.json

2) 出交付物:报告 + 逐文件 sha256 清单

ratchet-report build --dir ./delivery --policy policy.json

3) 收货方验证(不需要装 ratchet)

python3 verify.py ./delivery

仓库结构

目录语言是什么
cmd/ internal/Go机器上的引擎:工具清单 → 能力判定 → 最小权限策略。编译成单个静态二进制,目标机器不需要任何运行时
service/Python交付物侧:合规映射、sha256 清单、以及只用标准库的独立验证器
web/Nuxt 4 + Vue 3 + Tailwind公开页面:落地页 + 收货方在浏览器里自己算哈希的验证页
docs/—设计与计划(DESIGN.md / PLAN.md / DECISIONS.md)

状态

0.12.0 — developer preview,链路已经整条打通(本机实测:16 个 MCP server、 12 个未锁版本、164 个工具、策略 allow 43 / approve 106 / deny 15):

命令做什么
ratchet scan [--introspect] [--share page.html]读 harness 配置列出 MCP server(只读,不执行);加 --introspect 才连上去列工具
ratchet ingest / observe采集真实调用(hook 出错静默退出),并对照清单看出哪些工具从没被用过
ratchet policy draft / check编译三态策略(每条带判定依据),并试跑一次假设调用
ratchet deliver / report build一条命令出交付目录:策略 + 报告 + sha256 清单
ratchet mcp以 stdio MCP server 形态跑(ratchet_scan / ratchet_policy / ratchet_check)
ratchet feedback把去标识化结果整理成 issue 正文供你复制;没有遥测,不会自动发

拿到它的方式:curl -fsSL https://github.com/suhui-organization/ratchet/releases/latest/download/install.sh | sh、 brew install suhui-organization/tap/ratchet、容器 ghcr.io/suhui-organization/ratchet, 或官方 MCP Registry 里的 io.github.iversonwuwei/ratchet。

清楚的边界:能力判定是名称/描述的启发式,会双向出错(仓里有两条已知误判的测试); 它不是沙箱、运行时不拦调用;判定不了的会单独列出来请人确认,而不是猜一个结论。 详见 docs/PLAN.md 与 docs/DELIVERY-0.14.0.md。
