Overview

AI-generated overview

Lets an assistant look up a domain's public email setup and registration details from DNS data.

What it does
This remote MCP server exposes a domain mail check tool. Given a domain, it reports how that domain is configured for email and who it is registered with, based on public DNS records. It is a read-only lookup service with no declared tools beyond that check.
When to use it
Useful when you need a quick, assistant-driven check of a domain's mail configuration or registration details, for example during troubleshooting, due diligence, or verifying a sender domain.
Requirements
A remote streamable HTTP endpoint at no local runtime, package, account, API key, or environment variable is declared. Network access to the endpoint is required.
Before you install
The server is remote, so the domains you submit are sent to a third-party service. It is described as reading public DNS data only, but no authentication or privacy terms are declared, so avoid submitting sensitive or internal domain names.
