RunCheckovScan · AWS Terraform MCP Server MCP: Risk & Policy

WHAT IT DOES

What RunCheckovScan does on AWS Terraform MCP Server

AI agents invoke RunCheckovScan to trigger actions in AWS Terraform MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why RunCheckovScan needs a policy

This tool executes an external security scanning operation (Checkov) whose effects depend on the arguments provided (which files/modules to scan). It is not a simple read operation because scanning can trigger external processes and produce variable outputs based on detected issues. While the scan itself is non-destructive and informational, it qualifies as Execute because it runs an external tool/command.

From the tool's definition Tool name 'RunCheckovScan' indicates execution of Checkov security scanning. Server description states 'security scanning with Checkov' as a core feature. Checkov is a code scanning tool that analyzes infrastructure-as-code for security and compliance issues.
