Gives Claude 16 tools to analyze URLs across redirect chains, brand impersonation, domain age, SSL/TLS, parked detection, URL structure, and DNS records. Returns structured signals with configurable risk scores (0-100) instead of binary verdicts. You get 20 free checks, then pay per unknown domain while known domains and cached results stay free. Useful for batch lead list verification, link health audits, vendor vetting, or any workflow where you need domain intelligence at scale. Works as local MCP (stdio), hosted remote server, or REST API. Ships with a companion skill that teaches Claude to proactively check URLs before following them.
