Quick Install

Automated & IDE Setup

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.

One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.

Manual Client & Custom JSON ConfigExpand JSON ▾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for ratchet, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Documentation Overview

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。

Terminal
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):

bash
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:

bash
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

bash
# 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。

Frequently Asked Questions about Ratchet
