Agent Tool Security

Agent tool security refers to the safeguards and protocols that control which external tools and APIs an AI agent can access, and under what conditions. Organizations must implement permission controls, input validation, and audit logging to prevent agents from misusing tools in ways that could compromise data, systems, or compliance posture. This becomes critical as AI agents handle increasingly sensitive business processes and require clear boundaries around resource access.

OWASP GenAI Sets MCP Server Security Baseline for Enterprise Agents

OWASP GenAI has published a practical guide for secure MCP server development, covering authentication, authorization, session isolation, input validation, and hardened deployment. The guide establishes concrete controls against malicious server behavior, unauthorized tool invocation, and cross-session data contamination. For enterprises running agentic AI workloads, it now functions as a reference standard against which audit readiness will be measured.
