HOL Guard
HOL Guard brings antivirus-style runtime protection to AI agents. It evaluates supported agent actions and local artifacts for secret exposure, prompt injection, unsafe commands, malicious packages, and MCP risks. Guard can allow safe work, block known threats, pause ambiguous actions for approval, and record security receipts for later review.

Quick answers
Is Auth0 MCP Server better than HOL Guard?
Package installs favor HOL Guard: 82,400 monthly installs to 21,118. Auth0 MCP Server still ranks #4 of 182 maintained security servers. Data as of 2026-08-25; we haven't hands-on tested either.
Can I use Auth0 MCP Server and HOL Guard together?
Yes - MCP clients accept multiple servers in one config, so you can enable both security servers side by side. If their tools overlap, keep the one whose toolset fits to keep your agent's tool list lean.
What environment variables do their READMEs document?
Auth0 MCP Server: 1 environment variable extracted from the README setup; HOL Guard: no environment variables extracted from the README setup. Extraction does not rule out other authentication or configuration steps; check each project's current documentation.
