iDig DNS MCP 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:

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:

json

{
  "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
