What is SureCheck MCP?

Two tools. check_phone reads the numbering plan to say whether a number is well formed, which country it belongs to and what kind of line it is. check_email looks at the syntax and the domain: mail records, throwaway providers and role addresses such as info@.

Our check: Its maker sent it in and we wrote this page from what they published. We have not installed it yet, so there is no tool list or test result here. When it passes our own install check it moves to the main shelf.

Try asking

Are these five signup emails from throwaway domains?
A prompt to try once it is connected, written by MCP Shelf.

Worth knowing before you add it

It does not ask the carrier or the mail server, so it cannot tell you a number or inbox is live.

How do I connect SureCheck MCP?

What you need first

Free beta by invitation, with a fixed number of checks per key.

Its maker does not publish a server address on its own; the setup steps are on their website.

Full instructions are on surecheck-live-040.onrender.com. New to this? See the setup guides for Claude Code, Cursor, Claude Desktop and ChatGPT.

Before you add any community server

  • Hosted servers see whatever you send them. Check who runs it and what the sign-in can reach.
  • Servers that run on your computer can do what your user account can. Read the repository first.
  • Keep your app's “ask before each tool call” setting on until you trust it.
