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

  1. Subscribe to this server
  2. Sign up at SecurityTrails to get your API key (Free tier available)
  3. 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)

get_api_usage

Check current SecurityTrails API quota usage

get_associated_domains

Great for expanding the scope of an investigation. Find other domains associated with a target domain

get_dns_history

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

get_domain_details

Essential for mapping out a target domain's existing infrastructure. Get complete domain intelligence and current DNS records

get_domain_tags

Get classification tags for a domain

get_domains_by_ip

Essential for understanding shared hosting environments or identifying hidden vhosts. Find all domains pointed to a specific IP address

get_subdomains

Critical for attack surface mapping and asset discovery. Returns both active and inactive subdomains. Discover all subdomains for a given domain

get_whois

Get current WHOIS information for a domain

get_whois_history

Useful for OSINT investigations to uncover historical owners before privacy protection was enabled. Retrieve historical WHOIS records for a domain

search_dsl

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

Why OpenAI Agents SDK?

The OpenAI Agents SDK auto-discovers all 10 tools from SecurityTrails through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries SecurityTrails, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

  • Native MCP integration via MCPServerSse, pass the URL and the SDK auto-discovers all tools with full type safety

  • Built-in guardrails, tracing, and handoff patterns let you build production-grade agents without reinventing safety infrastructure

  • Lightweight and composable: chain multiple agents and MCP servers in a single pipeline with minimal boilerplate

  • First-party OpenAI support ensures optimal compatibility with GPT models for tool calling and structured output

FAQ

Frequently asked questions

01

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.

02

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.

03

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.

04

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.

05

Can I use multiple MCP servers in one agent?

Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.

06

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.

07
