Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Page executes code built at runtime public/pay.html:88

const say = (h, cls = '') => { $('status').className = 'box ' + cls; $('status').innerHTML = h; };

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

GW8 Signal API — questions

Answers built from our own checks of this server.

What can GW8 Signal API do?

It exposes 23 tools, read directly from the server on our last check. Among them: buy_day_pass, check_seller_reputation, check_spend_policy, get_band_dots, get_brief_teaser, get_coin and 17 more. 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 GW8 Signal API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 215 ms. The bar chart above shows every period we have measured.

How do I connect GW8 Signal API?

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 GW8 Signal API need an API key?

No. GW8 Signal API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 23 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is GW8 Signal API?

It answers our handshake in 215 ms on average, which is faster than 75% 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.

Is GW8 Signal API open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
