IDig DNS Server

A remote MCP server exposing 19 professional DNS diagnostic tools from the iDig API — built by Kedar Bhave ( Softricks ).

Connect any MCP-compatible AI client (Claude Desktop, Cursor, Windsurf, and more) to real DNS infrastructure. Diagnose outages, audit email security, validate DNSSEC, check SSL certificates, trace propagation across 16 global resolvers, and more — all in plain English.

Live endpoint: https://mcp.softricks.net/sse

Quickstart

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "idig-dns": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.softricks.net/sse"
      ]
    }
  }
}

Restart Claude Desktop. You'll see idig-dns appear under Connectors.

Cursor / Windsurf

Add to your MCP settings:

{
  "mcpServers": {
    "idig-dns": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.softricks.net/sse"
      ]
    }
  }
}

Authentication

All tools require a token parameter. Get your token at api.softricks.net/idig/docs.

Tools

Tool	Description
dns_lookup	Look up any DNS record type: A, AAAA, MX, NS, TXT, SOA, CAA, SRV, CNAME, DS, TLSA, HTTPS, SVCB
resolve_check	Resolution diagnostics — returns ok / nxdomain / servfail / timeout / degraded
diagnose	Full diagnosis combining resolution + DNSSEC — start here when something is broken
email_security_audit	SPF, DKIM, DMARC, and BIMI audit with A–F grade and prioritized fix recommendations
mx_check	MX health + provider detection (Google Workspace, M365, Proofpoint, 35+ providers)
dnssec_validate	DNSSEC chain of trust — returns secure / insecure / bogus / indeterminate
dnssec_health	Key inventory, signature expiry, algorithm assessment, rollover readiness
propagation_check	Check propagation across 16 global resolvers: Google, Cloudflare, Quad9, China, Korea, Russia
ssl_check	Certificate validity, expiry countdown, domain match, issuer, chain completeness
ttl_check	TTL advisory with step-by-step migration lowering plan
zone_consistency	Compare all authoritative nameservers — catches lame delegation and SOA mismatches
subdomain_discover	Probe 75 common subdomains + crt.sh Certificate Transparency logs — surfaces exposed dev/staging environments
geo_lookup	Geolocation, ISP, ASN, CDN detection, hosting flag
domain_status	EPP registrar lock status — transfer-ready, delete lock, serverHold, pendingDelete
blacklist_check	IP blacklist / DNSBL check — Spamhaus, Barracuda, SpamCop, SORBS, and more
whois_lookup	Parsed WHOIS data — registrar, expiry, domain age, nameservers, EPP status
http_check	HTTP/HTTPS reachability — status codes, redirect chain, HSTS, HTTP→HTTPS redirect
zone_axfr	AXFR zone transfer vulnerability check — tests if any NS allows public zone transfers
dane_validate	DANE/TLSA validation — cross-validates TLSA records against live TLS certificate

Example prompts

My emails are going to spam for example.com — token is YOUR_TOKEN

Did my DNS changes propagate yet for example.com? token: YOUR_TOKEN

Run a full security audit on example.com, token YOUR_TOKEN

Is the SSL cert for example.com about to expire? token YOUR_TOKEN

We're migrating example.com to a new host next week — are the TTLs safe? token YOUR_TOKEN

What subdomains does example.com have exposed? token YOUR_TOKEN

Are any of example.com's IPs on a blacklist? token YOUR_TOKEN

Get WHOIS info for example.com — token YOUR_TOKEN

Is example.com reachable over HTTPS? token YOUR_TOKEN

Check if example.com is vulnerable to zone transfers — token YOUR_TOKEN

Validate DANE/TLSA records for example.com — token YOUR_TOKEN
