What is the SecurityTrails MCP Server?
Connect your SecurityTrails account to any AI agent and empower your OSINT, bug bounty, and threat intelligence workflows with the world's most comprehensive domain and IP database.
What you can do
- Attack Surface Mapping — Instantly enumerate all subdomains for any target organization to map their external footprint
- Historical DNS Analysis — Look back in time at DNS records (A, MX, NS, TXT) to find hidden infrastructure, bypassed firewalls, or legacy systems
- Reverse IP Lookups — Find all domains hosted on a specific IP address to identify shared hosting or related corporate assets
- Advanced Threat Hunting — Use the SecurityTrails DSL (Domain Specific Language) to query the entire internet for specific tech stacks or vulnerable infrastructure
- Ownership Intelligence — Access current and historical WHOIS records to track domain ownership changes and unmask hidden threat actors
- Corporate Associations — Discover domains strongly associated with your primary target to expand your investigation scope
How it works
- Subscribe to this server
- Sign up at SecurityTrails to get your API key (Free tier available)
- Run intelligence queries directly from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Security Researchers & Pentesters — accelerate recon and asset discovery during engagements
- Bug Bounty Hunters — find forgotten subdomains and out-of-scope assets associated with target companies
- Threat Intelligence Analysts — correlate IPs, domains and WHOIS records to track APT infrastructure
- Brand Protection Teams — identify typosquatting and malicious domains targeting your organization
- System Administrators — audit their own external attack surface and verify DNS propagation
Built-in capabilities (10)
Check current SecurityTrails API quota usage
Great for expanding the scope of an investigation. Find other domains associated with a target domain
Useful for finding old IPs that might still be hosting vulnerable software, or tracking infrastructure migration over time. Retrieve historical DNS records for a domain
Essential for mapping out a target domain's existing infrastructure. Get complete domain intelligence and current DNS records
Get classification tags for a domain
Essential for understanding shared hosting environments or identifying hidden vhosts. Find all domains pointed to a specific IP address
Critical for attack surface mapping and asset discovery. Returns both active and inactive subdomains. Discover all subdomains for a given domain
Get current WHOIS information for a domain
Useful for OSINT investigations to uncover historical owners before privacy protection was enabled. Retrieve historical WHOIS records for a domain
Examples: `ipv4="1.1.1.1" AND mx="alt1.aspmx.l.google.com"` or `whois_email="admin@example.com"`. Check SecurityTrails docs for full DSL syntax. Advanced search using SecurityTrails DSL

Frequently asked questions
Is the SecurityTrails API free to use?
SecurityTrails offers a Free Tier API plan which allows 50 API requests per month. This is excellent for specific, targeted OSINT investigations. For automated or large-scale recon, you would need a commercial subscription.
What is historical DNS good for?
Companies often migrate infrastructure and hide behind WAFs like Cloudflare. Historical DNS reveals the original origin IP addresses used before the WAF was implemented, which might still be active and vulnerable to direct attacks. It's a critical tool in penetration testing.
How can I find related domains for a target company?
Use the get_associated_domains tool. It uses proprietary correlation to find other domains owned by the same entity. You can also use get_domains_by_ip to find what else is hosted on their IP space.
How does the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
createMCPClient is not a function
Install: npm install @ai-sdk/mcp
