1gateway — questions

Answers built from our own checks of this server.

What can 1gateway do?

It exposes 15 tools, read directly from the server on our last check. Among them: base_token_risk, convert_to_markdown, domain_lookup, fx_rates, kr_apartment_trades, kr_apartment_trades_summary and 9 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 →

What is 1gateway mostly used for?

Its tools cluster around trade and apartment. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is 1gateway 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 409 ms. The bar chart above shows every period we have measured.

How do I connect 1gateway?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does 1gateway need an API key?

No. 1gateway completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 15 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is 1gateway?

It answers our handshake in 409 ms on average, which is faster than 34% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
