HProxy MCP server

A free proxy list, a live proxy checker and an IP lookup for AI assistants, hosted by HProxy at one address. No key, no account, nothing to install.

https://mcp.hproxy.com/mcp

It speaks MCP over Streamable HTTP and is listed in the official MCP Registry as com.hproxy/mcp.

The tools

All three only read. None of them needs a key.

Things to ask

• "Give me twenty elite German SOCKS5 proxies and check which are alive."

• "Find five fast US HTTP proxies, test them, and give me only the working ones."

• "Who runs the network behind 8.8.8.8, and where is it?"

Good to know

• These are public free proxies. Expect fewer than half to answer at any moment, set short timeouts, and never send passwords or personal data through one.

• Limits are per IP address. The checker allows roughly twelve checks a minute with bursts of ten, because every check opens a real connection. Past a limit, the tool says how many seconds to wait.

• For proxies that must hold up against real blocking, HProxy's paid proxies are at hproxy.com/pricing.

The same tools without MCP

Plain HTTP, no key, CORS open:

curl "https://hproxy.com/api/proxy-list?format=json&protocol=socks5&country=us"
curl "https://hproxy.com/api/proxy-check?proxy=IP:PORT"
curl "https://hproxy.com/api/ip/8.8.8.8"

Documentation: free proxy list API, proxy checker API, IP lookup API. Written for language models: hproxy.com/llms.txt.

From a terminal, the hproxy command comes with the free HProxy app:

hproxy list --country DE --protocol socks5 --limit 20
hproxy check 203.0.113.7:1080 198.51.100.3:8080
hproxy ip 8.8.8.8

The whole list as plain files, updated around the clock: hproxy-com/free-proxy-list.
