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.

HardwareMCP — questions

Answers built from our own checks of this server.

What can HardwareMCP do?
It exposes 4 tools, read directly from the server on our last check. Among them: get_server, list_devices, recommend_for_device, search_servers. 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 HardwareMCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 13 of 92 checks got a reply (14.1%), average response time 460 ms. The bar chart above shows every period we have measured.
The registry lists HardwareMCP 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 HardwareMCP?
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 HardwareMCP need an API key?
No. HardwareMCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is HardwareMCP?
It answers our handshake in 460 ms on average, which is faster than 26% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is HardwareMCP 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 hardwaremcp.khanex.ai, which runs on its operator's own terms.
