HOL Guard

Local-first runtime firewall for AI coding agents

Overview

HOL Guard evaluates supported coding-agent actions locally before or after execution and can route risky changes through approvals and receipts. It provides command and MCP coverage, policy routing, review evidence, and fail-closed enforcement for its DeepSeek Harness integration.

✓ Best For

  • ✓ Developers running AI coding agents locally
  • ✓ Teams seeking policy controls around agent tool execution
  • ✓ Users who need review and evidence for risky agent actions

✗ Not Ideal For
