ToolGuard: Sandboxed Execution for Reliable Agent Tool-Use
ToolGuard provides production-grade sandboxing that catches 97% of tool misuse while preserving 95% of legitimate calls, solving agent safety at scale.
Agent tool-calling remains a security nightmare: parameter injection, logic bombs, and semantic misuse slip through. ToolGuard fixes this with triple defense: semantic intent classification (“is this call legitimate?”), parameter schema validation, and Docker sandbox execution with auto-rollback.
What changed. Catches 97% of malicious calls pre-execution with 4.8% false positives—first production-viable tool safety.
Red-teamed across ToolBench + custom attacks, it blocks SQL injection, prompt injection, and semantic misuse while preserving legit calls. Rollback ensures zero persistent damage. Docker integration makes it deployable today.
Why it matters. Unlocks unrestricted tool access for agents without enterprise security teams—essential for SaaS deployment.
Builder takeaway. ToolGuard + semantic validator = deploy tools safely today. Open-source Docker integration ready. Paper
