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.

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.

Fuci — questions

Answers built from our own checks of this server.

What can Fuci do?

It exposes 9 tools, read directly from the server on our last check. Among them: argus_bonding, argus_launches, fuci_agent, fuci_kya, fuci_quick, fuci_reputation and 3 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 Fuci mostly used for?

Its tools cluster around fuci and argus. 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 Fuci working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 487 ms. The bar chart above shows every period we have measured.

The registry lists Fuci as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Fuci?

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 Fuci need an API key?

No. Fuci completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

Is Fuci open source?

The code is open source: it is published under the MIT licence, written in TypeScript, 2 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at fuci.family, which runs on its operator's own terms.
