Overview

AI-generated overview

Lets an assistant run email deliverability checks on domains, covering SPF, DKIM, DMARC, BIMI, MTA-STS, blacklists, headers, and spam words.

What it does
Powerline Email Tools is a remote MCP server that exposes email deliverability checks to an assistant. According to its registry description, it covers SPF, DKIM, DMARC, BIMI, MTA-STS, blacklists, headers, and spam words. No individual tools are listed in the manifest, so the exact tool names and inputs are not documented here.
When to use it
Worth adding when you need to diagnose why mail from a domain is failing authentication, landing in spam, or being blocked, and want an assistant to walk through the relevant DNS records and reputation signals. Less useful if you only send mail through a provider that already handles deliverability.
Requirements
A remote MCP endpoint at over streamable HTTP. The manifest declares no authentication, no environment variables, and no headers, and no packages. Network access to the endpoint is required.
Before you install
The manifest declares no authentication, so consider whether the endpoint should be reachable without credentials and what domain names you send to it. The checks described are read-only lookups, but the queried domain names and any email headers you submit go to a third-party service.
