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：

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。

线上脚本和本仓库 main 分支一致，可以自己核对：

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

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。

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 httpsproxy / HTTPSPROXY / httpproxy / HTTPPROXY 和 ~/.claude/settings.json 里的 env；不支持 SOCKS，不读 ALLPROXY**（官方文档）。

MCP（给 AI Agent 用）

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

# Claude Code
claude mcp add --transport http ipjudge https://ipjudge.org/mcp

// Cursor / Windsurf / 其他支持远程 MCP 的客户端
{ "mcpServers": { "ipjudge": { "url": "https://ipjudge.org/mcp" } } }

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

curl ipjudge.org/api/ip/8.8.8.8                       # JSON，无需 key
curl -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。

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 httpsproxy / HTTPSPROXY / httpproxy / HTTPPROXY 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):

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