DATPAQ exposes 34 production data & utility APIs through one hosted MCP endpoint. Give any MCP client access to IP geolocation & intelligence, DNS / WHOIS / MX / domain lookups, email & phone validation, currency exchange rates, precious metals, aircraft & VIN lookups, web scraping & screenshots, unit/time conversion, dictionary/thesaurus/spell-check, company enrichment, and more — all with a single connection. Authenticate per-request with your Datpaq API key (Authorization: Bearer <key>); the server holds no credentials, so one instance serves many tenants.

Uptime, SSL, DNS and domain monitoring you can talk to — check, create and manage monitors for all your client sites from Claude or any MCP client. Sentinel is monitoring built for agencies and freelancers managing client websites: ask "which client SSL certificates expire this month?", "what was uptime across all sites in June?", or "add monitoring for newclient.com" in plain language. 21 tools cover creating, updating, pausing and deleting monitors, incident management, on-demand URL checks, uptime summaries, DNS and performance history, expiring-certificate reports, status pages, and a needs-attention digest. Hosted remote server (Streamable HTTP, OAuth or API token) — nothing to install. Requires a paid plan: read access from Starter, full read/write on Pro and Business.

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.
