DMARKOFF MCP connects your DMARC monitoring data to AI assistants via the Model Context Protocol. Instead of opening a dashboard, you ask questions and get answers — domain health, compliance stats, SPF/DKIM diagnostics, anomaly detection, and sender analysis. Works with Claude, ChatGPT, Cursor, and any MCP-compatible client.

DMARKOFF MCP connects your DMARC monitoring data to AI assistants — Claude, ChatGPT, Cursor, Windsurf — via the Model Context Protocol. Instead of opening a dashboard and building filters, you ask questions and get real answers backed by actual data. Ask which domains dropped in compliance, why SPF is failing on a specific domain, which senders are causing DKIM failures, or whether yesterday's traffic looks anomalous compared to the 14-day baseline. The AI picks the right tool, queries your account data, and gives a concrete answer with numbers and actionable recommendations. 17 tools covering the full diagnostic flow: project overview, domain health, SPF/DKIM records, compliance stats, daily timeline, sending source analysis (by ISP, IP, hostname, or reporter), anomaly detection, geo breakdown, and live DNS checks for any domain — no account needed for DNS tools. Access is scoped to your DMARKOFF account via API key authentication with OAuth 2.1 support. All tools are read-only.

28 WhoisXML API tools for AI agents — WHOIS lookups & history, reverse WHOIS, DNS lookup & history, reverse DNS/MX/NS, IP geolocation, IP netblocks, SSL certificates, subdomain discovery, threat intelligence, domain categorization, email verification, typosquatting detection, and bulk variants for batched lookups. Stdio and Streamable-HTTP transports, OAuth 2.1 with PKCE for hosted mode, npm and Docker distributions.
