About MCP Servers for Security & Authentication

MCP servers for security scanning, authentication, secrets management, and access control. Nerq tracks 2,751 MCP servers in the security & authentication category, each assessed against 52 global AI regulations including the EU AI Act, US state AI laws (California SB53, Colorado SB205), UK AI Bill, and more. Compliance scores are weighted by jurisdiction penalty severity — jurisdictions with higher fines (like the EU AI Act at up to €35M) have more impact on the score than voluntary frameworks.
