opensquat
openSquat is an open-source tool that detects look-alike domains impersonating your brand, by scanning newly registered domains daily.
The openSquat MCP server enables AI assistants to detect domain squatting and brand impersonation threats through the Model Context Protocol. It provides tools for finding newly registered lookalike domains (typosquatting, phishing, IDN homograph attacks) that target specific brands or keywords. The server connects to openSquat's intelligence backend, allowing Claude and other MCP-compatible clients to search for domain threats and validate API credentials. Searches consume quota from the same openSquat account used for Premium API access.
