Gexno Web3 — questions

Answers built from our own checks of this server.

What can Gexno Web3 do?

It exposes 2 tools, read directly from the server on our last check. Among them: lookup_nft, lookup_wallet. 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 Gexno Web3 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 824 ms. The bar chart above shows every period we have measured.

How do I connect Gexno Web3?

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 Gexno Web3 need an API key?

No. Gexno Web3 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Gexno Web3?

It answers our handshake in 824 ms on average, which is faster than 9% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Gexno Web3 open source?

The code is open source: it is published under the MIT licence, written in JavaScript, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at api.gexno.com, which runs on its operator's own terms.
