WHY IT NEEDS A POLICY

Why planka_create_card needs a policy

Creating a card in Planka is a write operation that modifies board state reversibly. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. However, severity is medium rather than low because an AI agent could create many cards, spam the board, or pollute the workspace with unwanted data, creating operational disruption requiring manual cleanup.

From the tool's definition Tool name 'planka_create_card' and sibling tools including 'mcp_delete_card', 'mcp_delete_task' indicate a Planka board management API. The tool creates new cards (reversible data modification).
