Tech Stack Detector: Wappalyzer & BuiltWith Alt, CSV or Sheet missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Tech Stack Detector: Wappalyzer & BuiltWith Alt, CSV or Sheet — questions

Answers built from our own checks of this server.

Why is there no tool list for Tech Stack Detector: Wappalyzer & BuiltWith Alt, CSV or Sheet?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is Tech Stack Detector: Wappalyzer & BuiltWith Alt, CSV or Sheet 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 347 ms. The bar chart above shows every period we have measured.
How do I connect Tech Stack Detector: Wappalyzer & BuiltWith Alt, CSV or Sheet?
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. You will need your own key: it refuses anonymous clients.
Does Tech Stack Detector: Wappalyzer & BuiltWith Alt, CSV or Sheet need an API key?
Yes. Every time we knock, Tech Stack Detector: Wappalyzer & BuiltWith Alt, CSV or Sheet answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Tech Stack Detector: Wappalyzer & BuiltWith Alt, CSV or Sheet?
It answers our handshake in 347 ms on average, which is faster than 41% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
