Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

pool
pool_build_proxy_url
Build a ready-to-use Pool Gateway proxy URL (gw.proxies.sx, HTTP 7000 or SOCKS5 7001). Local, no network. Take proxyUsername and password from pool_get_my_credentials (a reseller passes a customer pak_ key as password). pool: "peer" is the main network (residential and mobile, most countries), "mbl" is carrier modems in US, GB, FR, NL, PL and GE (Georgia) only, "any" or "best" let the gateway choose. Rotation: sticky and hard both hold one device, auto5/auto10/auto20/auto60 move to another device on that interval, ondemand picks again on each new connection; sticky, hard and auto* only persist across connections with a sid. Sticky holds the device, not the IP: a mobile carrier can still change the exit IP. The result contains the password.
pool_explain_error
Explain a Pool Gateway error and say what to do about it. Pass the error text your HTTP client got from gw.proxies.sx (it looks like "E_NO_STOCK_COUNTRY: ... (req: ...)") or just the code. Covers E_AUTH_INVALID, E_BALANCE_EXHAUSTED, E_NO_STOCK_COUNTRY, the rate and session limits and the rest. Local, no network.
pool_get_facets
List the cities, states, carriers (with ASN and class) and IP classes that have stock in one country, with counts, no account needed. The values are the ones pool_build_proxy_url accepts for city, state, carrier and asn. Pass city, state or carrier to see what remains once that filter is applied.
pool_get_stock
Get live Pool Gateway stock, no account needed. With a country: the mbl and peer endpoint counts there and the peer counts per class (mobile, residential, isp). Without: totals plus the count per country for both pools. Use it to pick a pool and country before pool_build_proxy_url.
service
get_service_status
Check whether Proxies.sx is healthy right now: open Pool Gateway incidents, the state of the API, gateway and relay, and recent uptime. No account needed. Call it when requests fail with 5xx or E_INTERNAL before retrying in a loop.

Proxies Sx MCP Server — questions

Answers built from our own checks of this server.

What can Proxies Sx MCP Server do?
It exposes 5 tools, read directly from the server on our last check. Among them: get_service_status, pool_build_proxy_url, pool_explain_error, pool_get_facets, pool_get_stock. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Proxies Sx MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 128 ms. The bar chart above shows every period we have measured.
How do I connect Proxies Sx MCP Server?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Proxies Sx MCP Server need an API key?
No. Proxies Sx MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Proxies Sx MCP Server?
It answers our handshake in 128 ms on average, which is faster than 87% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Proxies Sx MCP Server?
The npm package @proxies-sx/mcp-server was installed 290 times in the last week. Week over week that is +544%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Proxies Sx MCP Server open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at api.proxies.sx, which runs on its operator's own terms.
