What it can touch

  • Runs on the publisher’s servers

    Nothing is installed on your computer. Whatever your AI sends to it goes to urlcheck.ai, so read their privacy terms for anything sensitive.

    How we know

    The registry entry lists a remote streamable-http endpoint at urlcheck.ai.

  • Needs your API key

    You need an account with the service and your own key. It goes in your AI’s settings or config file — never in a chat.

    How we know

    The registry entry marks X-API-Key as required secret.

  • Version 0.1.5

    The latest version its publisher has registered.

    How we know

    registry.modelcontextprotocol.io, latest entry.

  • Publisher identity checked, code not reviewed

    The official MCP registry confirms who controls this name. It does not review what the server does — and neither has Launch7.

    How we know

    The registry authenticates namespaces and delegates security scanning (modelcontextprotocol.io/registry/about).

Read from the official MCP registry entry on 28 Sept 2026. Launch7 has not run this server or reviewed its code. How we check

Add it to your AI

Partly. Claude connects by URL, but this server wants a key in a header, which Claude’s connector form cannot send unless the server offers sign-in.

  1. Server address
    https://urlcheck.ai/mcp

  2. In Claude, open Customize → Connectors, press +, then Add custom connector. Paste the address and save.

  3. If the service asks you to sign in, do it in the window that opens. Then turn the connector on in a chat from the + menu.

Needs your own X-API-Key from the service. Replace the placeholder — never paste a key into a chat.

How Claude does this: support.claude.com · checked 28 Sep 2026 · “Supported” means documented by the vendor; Launch7 has not run it end to end

Worth knowing

  • It reaches urlcheck.ai and nothing else. Another service needs its own server.
  • No licence is stated, so Launch7 links to it rather than bundling it.
  • It runs on someone else’s server. If that endpoint goes down or changes, this page cannot tell you.
