Stienhardt — questions

Answers built from our own checks of this server.

What can Stienhardt do?
It exposes 14 tools, read directly from the server on our last check. Among them: ask_business, cancel_cart, cancel_checkout, complete_checkout, create_cart, create_checkout and 8 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 Stienhardt mostly used for?
Its tools cluster around checkout, cart and cancel. 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 Stienhardt 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 165 ms. The bar chart above shows every period we have measured.
Is Stienhardt still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Stienhardt?
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 Stienhardt need an API key?
No. Stienhardt completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Stienhardt?
It answers our handshake in 165 ms on average, which is faster than 79% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
