DMARKOFF - DMARC, SPF & DKIM Analytics MCP Server

DMARC analytics inside your AI assistant. DMARKOFF MCP connects your DMARC monitoring data to AI assistants - Claude, ChatGPT, Cursor, Windsurf - through the Model Context Protocol. Instead of opening a dashboard and building filters, you ask a question and get an answer with real numbers behind it. Its 19 documented tools cover domain, dns, check, spf. It is available as a remote MCP endpoint.

Teams that want a hosted email endpoint instead of running a local process.
