mambalabsdev/mcp-domain-deliverability-checker

What it does

This MCP (Model Context Protocol) server automates domain email deliverability auditing. It comprehensively analyzes email authentication protocols and infrastructure health by checking SPF records, DKIM signatures, DMARC policies, MX records, mail provider identification, DNS blacklist status, catchall configuration, and domain age. The tool returns a normalized 0-100 health score indicating overall deliverability quality.

How to set up

Install the MCP server from the mambalabsdev GitHub repository. Configure it with your domain information and Apify credentials for backend processing. Once set up, the server integrates with compatible AI platforms (ChatGPT, Claude, etc.) to provide deliverability analysis through natural language requests.
