Overview

AI-generated overview

Remote IP Judge server that lets an assistant check an IP or its own network exit for residential vs datacenter status, AI-region support and service status.

What you can do
  • Judge any IPv4/IPv6 address: residential or datacenter, purity score 0-100, risk-list hits, and whether ChatGPT, Claude, Gemini and Muse accept its region and type
  • Judge the public exit IP of the machine sending the MCP request, to see whether the agent's own network would be accepted
  • Check whether a country is on the official support lists of ChatGPT, Claude, Gemini and Muse
  • Look up official live status of Claude, OpenAI, Cursor, GitHub, Cloudflare and others, refreshed every 3 minutes
When to use it
Useful when you want to know why an AI service may reject or restrict a connection: checking a proxy or VPS exit before using ChatGPT, Claude, Gemini or Muse, verifying whether a region is officially supported, or confirming whether a provider is currently having an outage.
Requirements
Remote Streamable HTTP endpoint at ipjudge.org/mcp; no key required. Anonymous use is limited to 40 new lookups per visitor per 10 minutes; more requires an API key sent as an Authorization Bearer header. Network access to ipjudge.org and to the providers' public status pages.
Before you install
The server sees the public IP of whichever machine sends the request, so web connectors reveal the platform's server exit rather than yours. Results are observations only and do not predict whether an account or API call will succeed. Bulk scanning is discouraged, and results should be credited to ipjudge.org. An optional API key is a credential to keep private.

Installation

In SourceWeft

  1. Open IP Judge in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/org.ipjudge%2Fipjudge/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

ipjudge.org —— 中立的 IP / 网络出口检测。用 ChatGPT、Claude、Gemini、Meta Muse 之前，先看清你的出口：住宅还是机房、地区是否受官方支持、有没有 DNS / WebRTC 泄露、终端和浏览器是不是走的同一条线路。

English

这个仓库放的是会在你机器上运行的部分，方便你在 curl | bash 之前先读源码：

文件作用一行运行
scripts/cc.shClaude Code / Codex 终端出口体检curl -sL ipjudge.org/cc | bash
scripts/check.sh服务器（VPS）一键体检bash <(curl -Ls ipjudge.org/sh)
server.jsonMCP 服务描述（官方 MCP Registry：org.ipjudge/ipjudge）见下文

两个脚本都是只读的：不安装任何东西、不改设置、不上传数据。发往 ipjudge.org 的请求只有一个：查询本机出口 IP 的判定（和你直接打开网站一样）。其余请求直接访问各平台的公开地址。

本仓库的脚本与线上同步更新，但线上发布并不由本仓库自动触发，二者可能短暂不一致。运行前请自己核对：

bash
diff <(curl -sL ipjudge.org/cc) scripts/cc.sh && echo 一致

有输出就说明线上版本比仓库新（或相反），以你实际读过的那一份为准；欢迎在本仓库开 issue。

终端出口体检（Claude Code / Codex）

Claude Code、Codex 跑在终端里，只认 HTTPS_PROXY 这类环境变量，不一定走浏览器用的代理。浏览器检测显示美国住宅，终端却可能直连出去。

bash
curl -sL ipjudge.org/cc | bash          # 中文curl -sL ipjudge.org/en/cc | bash       # English

按 Claude Code 官方规则判断代理：只认 https_proxy / HTTPS_PROXY / http_proxy / HTTP_PROXY 和 ~/.claude/settings.json 里的 env；不支持 SOCKS；官方文档只列了上面四个变量，没有提到 ALL_PROXY（官方文档）。

Agent Skill：在 Claude Code / Codex 里直接自检

skills/ipjudge-exit-check 是一个遵循 Agent Skills 规范 的技能：装好后，对 agent 说「帮我查一下终端出口」，它会运行内置的 exit-check.sh 并用大白话解释结果。

bash
# Claude Code（装到 ~/.claude/skills/）DO_NOT_TRACK=1 npx --yes skills add ipjudge/ipjudge --skill ipjudge-exit-check --global --agent claude-code --copy --yes# Codex / Cursor / GitHub Copilot / OpenCode（装到 ~/.agents/skills/）DO_NOT_TRACK=1 npx --yes skills add ipjudge/ipjudge --skill ipjudge-exit-check --global --agent codex --copy --yes

一定要带 --agent：不带的话安装器会把它复制进几十个不同工具的目录。

  • 只读：不改任何设置、不装东西。代理变量只报名称和形态，不打印地址、账号密码或 NO_PROXY 内容；不读 settings.json 的值。
  • 只往外发一次查询：把出口 IP 发给 ipjudge.org 取判定，其余请求是各平台公开的 /cdn-cgi/trace。
  • 只陈述观测到的事实：能看出「某个域名看到的是哪个 IP、哪个国家」，看不出账号、登录或 API 会不会成功，也不预测任何账号的结果。检查没跑完时会明确标「不完整」，不会说「没问题」。
  • 需要 bash 3.2+ 和 curl（macOS / Linux / WSL）；原生 Windows 请用网页版。
  • 安装器自带的统计请求用 DO_NOT_TRACK=1 关闭；脚本本身没有任何统计。
  • 测试：tests/run_tests.sh（全部使用本机假服务，不联网）。

MCP（给 AI Agent 用）

端点：https://ipjudge.org/mcp（Streamable HTTP，免费，不需要 key）

bash
# Claude Codeclaude mcp add --transport http ipjudge https://ipjudge.org/mcp
json
// Cursor / Windsurf / 其他支持远程 MCP 的客户端{ "mcpServers": { "ipjudge": { "url": "https://ipjudge.org/mcp" } } }
工具说明
my_exit判定发起 MCP 请求的那台机器的出口。Claude Code、Cursor 等本机客户端就是你的电脑；网页版 connector 由平台服务器发起请求，看到的是平台服务器的出口
check_ip判定任意 IPv4 / IPv6：住宅 / 机房、纯净度 0–100、风险名单命中、四家 AI 是否接受
ai_availability某国家 / 地区是否在 ChatGPT、Claude、Gemini、Muse 的官方支持名单里
service_statusClaude、OpenAI、Cursor、GitHub、Cloudflare 等的官方实时状态

不带 key 时每个访客 10 分钟最多 40 次新查询；需要更多，在 我的账户 创建 API key，加 --header "Authorization: Bearer ipj_你的key"。

HTTP API

bash
curl ipjudge.org/api/ip/8.8.8.8                       # JSON，无需 keycurl -H "Authorization: Bearer ipj_你的key" "https://ipjudge.org/api/v1/ip/8.8.8.8"

字段说明和配额见 ipjudge.org/tools/api/。展示结果时请注明「数据来自 ipjudge.org」并附链接；请勿批量扫描。

判定规则

规则全部公开：ipjudge.org/method/。觉得判错了，到 纠错页 提交，或在本仓库开 issue。

English

ipjudge.org is a neutral IP / network-exit checker. Before you use ChatGPT, Claude, Gemini or Meta Muse, see what your exit really looks like: residential or datacenter, whether the region is officially supported, DNS / WebRTC leaks, and whether your terminal takes the same route as your browser.

This repository holds the parts that run on your machine, so you can read them before piping to bash:

  • scripts/cc.sh — Claude Code / Codex terminal exit check: curl -sL ipjudge.org/en/cc | bash
  • scripts/check.sh — server (VPS) check: bash <(curl -Ls ipjudge.org/en/sh)
  • server.json — MCP server description, listed in the official MCP Registry as org.ipjudge/ipjudge

Both scripts are read-only: they install nothing, change nothing and upload nothing. The only request to ipjudge.org asks for the verdict on your own exit IP.

The terminal check follows Claude Code's documented proxy rules: only https_proxy / HTTPS_PROXY / http_proxy / HTTP_PROXY and the env block in ~/.claude/settings.json. SOCKS is not supported and ALL_PROXY is not read (docs).

MCP

Endpoint https://ipjudge.org/mcp (Streamable HTTP, free, no key needed):

bash
claude mcp add --transport http ipjudge https://ipjudge.org/mcp

Tools: my_exit (the exit of whichever machine sends the MCP request — your computer for Claude Code / Cursor; the platform's servers for web connectors), check_ip, ai_availability, service_status. Without a key: 40 new lookups per visitor per 10 minutes. For more, create a key under My account and send Authorization: Bearer ipj_YOURKEY.
