How to Enumerate Subdomains with OpenClaw

Subdomain enumeration with OpenClaw and ToolRouter. Discover all subdomains.

OpenClaw runs HTTP service probes as systematic, large-scale scanning operations that cover your entire web infrastructure in one pass. Feed it a list of domains, subdomains, and IP ranges to get back a comprehensive inventory of responding services with their security header status, SSL configuration, and detected technologies. Its batch scanning approach is essential for organizations managing large infrastructures that need continuous visibility into their HTTP attack surface.

Connect ToolRouter to OpenClaw

1Install the CLI

npm install -g toolrouter-mcp

2Call tools directly from OpenClaw

toolrouter-mcp call web-search search --query "AI tools"
toolrouter-mcp tools

Steps

Once connected (see setup above), use the Security HTTPx tool:

Ask OpenClaw: "Enumerate all subdomains of my domain"
OpenClaw discovers and probes subdomains
Review the complete subdomain inventory
Secure or decommission any unintended subdomains

Example Prompt

Try this with OpenClaw using the Security HTTPx tool

Discover all subdomains of mycompany.com and check which ones have live HTTP services.

Tips

Forgotten subdomains running old software are among the easiest targets for attackers
Maintain a living inventory of all authorized subdomains and compare against scan results
Wildcard DNS records can mask subdomain takeover vulnerabilities -- check for these
