B2B Email & Domain Scorer 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.

B2B Email & Domain Scorer — questions

Answers built from our own checks of this server.

What can B2B Email & Domain Scorer do?

It exposes 2 tools, read directly from the server on our last check. Among them: score_domain, score_email. 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 B2B Email & Domain Scorer working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 184 of 184 checks got a reply (100.0%), average response time 301 ms. The bar chart above shows every period we have measured.

How do I connect B2B Email & Domain Scorer?

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 credentials: it refuses anonymous clients.

Does B2B Email & Domain Scorer need an API key?

Yes. Every time we knock, B2B Email & Domain Scorer 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 B2B Email & Domain Scorer?

It answers our handshake in 301 ms on average, which is faster than 55% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is B2B Email & Domain Scorer open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
