Quantumcompanies — questions

Answers built from our own checks of this server.

What can Quantumcompanies do?

It exposes 11 tools, read directly from the server on our last check. Among them: get_course, get_listing, get_product, get_stats, list_categories, list_courses and 5 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 Quantumcompanies working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 13 of 13 checks got a reply (100.0%), average response time 614 ms. The bar chart above shows every period we have measured.

How do I connect Quantumcompanies?

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 Quantumcompanies need an API key?

No. Quantumcompanies completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 11 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Quantumcompanies?

It answers our handshake in 614 ms on average, which is faster than 17% 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.
