Name: IP Location MCP
Author: pianam

IPv4 geolocation lookup with Chinese output — country/region/city, coordinates, timezone and ISP/ASN info, with automatic fallback between two free providers.

Try it in 30 seconds: a free public MCP endpoint is already running — just paste the URL into your MCP client (no install, no API key).
Or self-host: a single Python file, stdlib HTTP + FastMCP, zero paid dependencies.

⚡ Use the hosted endpoint (no setup)

https://mcp.pianam.cn/ip-mcp/mcp

Transport: Streamable HTTP (MCP 2025-03-26 compatible). No authentication required.

🔌 Client configuration

Add this to your MCP client's mcpServers configuration (Claude Desktop claude_desktop_config.json, Cursor mcp.json, Cline, Cherry Studio, etc.):

json

{
  "mcpServers": {
    "ip-location": {
      "type": "http",
      "url": "https://mcp.pianam.cn/ip-mcp/mcp"
    }
  }
}

Clients that do not accept "type": "http" (some Cherry Studio / older Cline versions) accept the same entry with just "url".

🧰 Tools

Tool	Parameters	Returns
`query_ip_location(ip="", ctx=None)`	`ip`: IPv4 address, e.g. `"8.8.8.8"`. Empty: attempts the caller's own public IP (via X-Forwarded-For).	归属地 (country/region/city), coordinates, timezone, ISP, organization and AS number — in Chinese. Error message for invalid/non-IPv4 input.

📡 Data sources, caching & limits

Primary source: ip-api.com — free endpoint with direct Chinese-language output.
Automatic fallback: ipwho.is (free, 10k requests/month) with built-in English→Chinese country/province mapping (all Chinese provinces + US/AU/JP/KR common regions).
Results cached for 24 hours (geolocation barely changes); hosted endpoint rate-limited to 200 requests / minute / IP.
No API key, no login; read-only lookups.

🐢 Self-hosting

bash

git clone https://github.com/boy-373/ip-location-mcp.git
cd ip-location-mcp
pip install -r requirements.txt
python ip_lookup_mcp_server.py
# the server listens on 127.0.0.1:8006 by default; override with:
#   MCP_HOST=0.0.0.0 MCP_PORT=9000 python ip_lookup_mcp_server.py
#   MCP_ALLOWED_HOSTS="your-domain.com,127.0.0.1:*"
#   MCP_ALLOWED_ORIGINS="https://your-domain.com"

Then point your MCP client at http://127.0.0.1:8006/mcp. No API keys or accounts are ever required.

🐳 Self-host with Docker

Option A — pull the pre-built image (fastest, no build):

bash

docker run -d -p 8000:8000 --name ip-location-mcp ghcr.io/boy-373/ip-location-mcp:latest

Option B — build from source:

bash

git clone https://github.com/boy-373/ip-location-mcp.git
cd ip-location-mcp
docker build -t ip-location-mcp .
docker run -d -p 8000:8000 --name ip-location-mcp ip-location-mcp

Then point your MCP client at http://127.0.0.1:8000/mcp. The container listens on 0.0.0.0:8000 by default (override with -e MCP_PORT=9000 and adjust -p accordingly). No API keys or accounts required.

🇨🇳 中文使用说明

一句话：IP 归属地查询，国家/省份/城市/运营商/ASN 全中文输出，主备双通道高可用。

在线直连地址（免费、无需 Key、开箱即用）：https://mcp.pianam.cn/ip-mcp/mcp

在 MCP 客户端（Claude Desktop / Cursor / Cherry Studio / Cline 等）的配置里加入：

json

{
  "mcpServers": {
    "ip-location": {
      "type": "http",
      "url": "https://mcp.pianam.cn/ip-mcp/mcp"
    }
  }
}

工具：

query_ip_location(ip)：查 IPv4 归属地。传 IP 地址（如 8.8.8.8）；留空时尝试查询调用方自己的公网 IP。
返回国家/省份/城市、经纬度、时区、运营商、组织、AS 编号，中文输出。
主数据源 ip-api.com（免费、中文直出），故障自动切换 ipwho.is（含中国省份拼音中文化映射）。

服务特性：数据源全部为公开接口、无需注册/付费；服务端内存缓存、失败自动降级/切换备用通道；单 IP 限流 200 次/分钟。

本地部署：

bash

git clone https://github.com/boy-373/ip-location-mcp.git
cd ip-location-mcp
pip install -r requirements.txt
python ip_lookup_mcp_server.py
# 默认监听 127.0.0.1:8006，可用环境变量 MCP_HOST / MCP_PORT / MCP_ALLOWED_HOSTS / MCP_ALLOWED_ORIGINS 覆盖

Docker 自托管：

bash

# 方式一：直接拉预构建镜像（最快，无需构建）
docker run -d -p 8000:8000 --name ip-location-mcp ghcr.io/boy-373/ip-location-mcp:latest

# 方式二：从源码构建
git clone https://github.com/boy-373/ip-location-mcp.git && cd ip-location-mcp
docker build -t ip-location-mcp .
docker run -d -p 8000:8000 --name ip-location-mcp ip-location-mcp
# MCP 地址填：http://127.0.0.1:8000/mcp

容器默认监听 0.0.0.0:8000（可用 -e MCP_PORT=端口 改），无需任何 API Key 或账号。

🔌 Use with Any AI Client — One-Click MCP Gateway

We host a free MCP aggregation gateway: your AI assistant (Cherry Studio, Claude Desktop, Cursor, Cline — any MCP client) discovers and uses MCP tools through a single URL:

https://mcp.pianam.cn/ai/mcp

Add it once, then talk in plain language — the AI automatically searches → inspects → calls the right MCP for you.

🔍 Search across 22,000+ indexed MCP servers (Chinese & English)
⚡ 50+ live hosted MCPs callable directly out of the box (weather, exchange rates, hot trends, IP geo, train tickets…)
📦 GitHub-based MCPs: search finds them with links to install locally
✅ Servers health-checked weekly — alive ones ranked first
🆓 Free to use, no key required
