Overview

AI-generated overview

Lets an assistant check a domain's DMARC, SPF and DKIM records, build SPF records, explain bounces, and read DMARC reports.

What it does
DomainCanary is a remote MCP server for email authentication diagnostics. According to its description, it checks a domain's DMARC, SPF and DKIM records, helps build SPF records, explains bounce messages, and reads DMARC reports. No individual tools are listed in the manifest.
When to use it
Useful when someone needs to diagnose why email from a domain fails authentication or lands in spam, or wants help interpreting DMARC aggregate reports and bounce messages. It is aimed at email deliverability and domain configuration work rather than general development tasks.
Requirements
A remote streamable HTTP endpoint at the provider's site; no package installation is needed. The manifest declares no authentication, environment variables or headers, so no credentials appear to be required.
Before you install
The manifest declares no authentication, so consider whether the endpoint should be reachable without credentials. Domain and DNS lookups are sent to the provider's service, and any SPF or DNS changes suggested should be reviewed before being applied to live records.
