- Monitoring
A DNS record changes without your knowledge. An SSL certificate expires on a Friday night. A DMARC misconfiguration sends thousands of emails to spam. These are not edge cases — they are the reason EdgeDNS exists.
Connect your AI to live DNS and domain checks
Free on every plan.
EdgeDNS speaks a protocol called MCP that AI assistants already understand. Connect once, and your AI can look up DNS records, check email security, audit SSL certificates, detect tech stacks, and run full domain reports — all by asking in plain English. No code. No learning curve. Just ask.
- Works with MCP-compatible clients including Claude, ChatGPT, Gemini, and Cursor
- Live data from actual servers — not guesses from training data
- 106 available MCP tools, with access based on your plan
“Check the security posture of edgedns.dev — speed, accessibility, and overall score.”
The problems you don't see are the ones that hurt most
Private alerts, email authentication, record verification, and security scoring. Use the API directly or let your AI call the right tools through MCP.
Domain Monitoring
Track DNS changes and certificate expiration on a configurable schedule. EdgeDNS privately tracks DNS records, SSL certificates, ownership data, and 5 health scores for every domain you add.
Learn more →MCPEmail Security
Stop emails from landing in spam. Validate your sending domain's authentication — SPF (who can send as you), DKIM (message integrity), and DMARC (enforcement policy) — before you hit send. Get a letter grade and steps to fix problems.
Learn more →MCPDNS Lookup
Query DNS records and compare answers across public resolvers. Verify web, mail, and security record changes, investigate differences, and account for TTL-based caching.
Learn more →MCPSecurity Analysis
Assess HTTP security headers, SSL certificates, DNSSEC, and email authentication. Export technical findings to support internal reviews and compliance evidence collection.
Learn more →MCPDomain Intelligence
See everything about a domain in one request. Ownership records, SSL certificates, the technology stack, and hosting details. Use it for due diligence, competitive research, or vendor assessment.
Learn more →MCPIP Geolocation
Look up an IP address’s approximate location, ASN, network, and risk signals. Enrich security alerts and fraud reviews with context from structured API responses.

Once connected, just ask. Your AI picks the right tools automatically.
Security teams
“Audit the security posture of acme.com — headers, SSL, DNSSEC, everything”
Email marketers
“Check if our DMARC policy will cause the next campaign to land in spam”
Developers
“Compare the tech stacks of competitor1.com and competitor2.com”
Compliance
“Check DNS, TLS, and security headers for all five of our production domains”
Real problems. Real solutions.

One API key. Two ways to use it.
Call any endpoint directly with curl, Python, or any HTTP client. Or connect via MCP and let your AI call the right tools for you. Same API key, same structured JSON, same privacy guarantees.
- Works with any language or HTTP client
- Structured, consistent JSON for every endpoint
- Built-in caching and global edge delivery
- Private by default — your results are never shared
- MCP-compatible — your AI uses the same endpoints

Frequently asked questions
- What is EdgeDNS?
- EdgeDNS is a service that privately monitors your domains and alerts you when something goes wrong — DNS changes, expiring certificates, broken email authentication, or declining security scores. It also provides on-demand lookups for domain ownership, technology stacks, IP geolocation, and more. Everything runs on Cloudflare's global network for fast responses worldwide. You can use it through a standard API or let AI assistants (Claude, ChatGPT, Gemini) use it directly.
- Is my domain data shared with anyone?
- No. EdgeDNS is private by design. Your queries and results are never shared, sold, or fed into passive databases. Only your organization can see what you look up.
- What can I do on the free tier?
- The free tier includes 200 requests per month, MCP access to Free-supported tools, and 5 watches checked daily on Free-supported endpoints. Watch checks and MCP lookups share your request allowance. No credit card required. No time limit.
- How does private domain monitoring work?
- Create a watch for an endpoint through the dashboard or API. Free includes 5 watches checked daily; Developer includes 50 from 30 minutes; Pro includes 250 from 5 minutes. Endpoint tier restrictions apply. Scheduled checks share your monthly request allowance. Each watch keeps snapshots and compares supported changes; configure notification recipients for alerts.
- Do I need to install anything?
- No. EdgeDNS is a REST service — call it from any HTTP client. For AI integration, connect to our MCP server at mcp.edgedns.dev/mcp. No SDK, no agent to install, and no wrapper code needed.
- What is MCP and how does it work with EdgeDNS?
- MCP is an open standard that lets AI assistants like Claude, ChatGPT, and Gemini use real tools — not just generate text about them. When you connect EdgeDNS through MCP, your AI can actually look up DNS records, check email authentication, run security audits, and more. It calls eligible lookup tools available to your plan, and the AI chooses tools based on what you ask. Think of it as giving your AI a toolbox instead of a textbook. MCP is included on all plans, including the free tier. Available tools and request limits depend on your plan.
- Which AI tools and clients does EdgeDNS support?
- EdgeDNS works with any MCP-compatible client: Claude Code, Claude Desktop, ChatGPT, Gemini CLI, OpenAI Responses API, Cursor, Windsurf, Cline, and more. Setup takes one command — see our MCP integration guide for details.
- What happens if I don't monitor my domains?
- Most domain problems are invisible until they cause damage. A misconfigured DNS record can silently redirect traffic. An expired SSL certificate locks customers out of your site. A broken DMARC policy can cause authentication failures or rejected mail. These happen every day to teams that rely on manual checks or no checks at all.
Domain problems don't wait. Neither should you.
Track DNS changes, expiring certificates, email auth failures, and security score drops. Start with free API lookups, MCP access, and 5 watches checked daily on Free-supported endpoints. Upgrade for more watches, faster intervals, and additional endpoints.
Includes MCP for Claude, ChatGPT, and Gemini. 200 requests/month. No credit card required.
