WHAT IT DOES

What generate_qr_batch does on Enhanced QR Code MCP Server

AI agents use generate_qr_batch to create or update resources in Enhanced QR Code MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced QR Code MCP Server environment.

WHY IT NEEDS A POLICY

Why generate_qr_batch needs a policy

This tool creates and generates QR code images, which are new data artifacts. While the action is reversible (generated images can be deleted), it modifies the system state by creating new files/resources. This falls under Write category rather than Read (which would only retrieve existing QR codes).

From the tool's definition Tool name 'generate_qr_batch' combined with description 'Generate multiple QR codes in batch' indicates creation of multiple data artifacts (QR code images).
