Overview

AI-generated overview

Lets an assistant look up a domain's tech stack, email security records, and domain age through a hosted API.

What it does
DomainDNA is a remote MCP endpoint that exposes domain intelligence lookups. Based on its description, it returns a domain's technology stack, email security configuration such as SPF and DMARC records, the MX provider, and the domain's age. It is hosted by the provider, so no local installation is involved.
When to use it
Useful when an assistant needs quick background on a domain, for example checking a vendor's email authentication posture or how long a site has existed. It is a lightweight lookup service rather than a full security or reconnaissance suite.
Requirements
A remote MCP client that supports streamable HTTP, pointed at the provider's hosted endpoint. No local runtime or package is needed. An optional paid-plan API key is supplied in the x-api-key header; without it the service is limited to 25 free domains per day.
Before you install
The optional x-api-key header carries a paid-plan credential, so treat it as a secret and avoid exposing it in logs or shared configuration. Lookups are sent to the provider's hosted service, so domain names you query leave your machine. The free tier is capped at 25 domains per day, and paid usage may involve cost.
