About 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.
Cline operates autonomously inside VS Code — it reads your codebase, plans a strategy, and executes multi-step tasks including SecurityTrails tool calls without waiting for prompts between steps. Connect 10 tools through the Vinkius and Cline can fetch data, generate code, and commit changes in a single autonomous run.
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
