What create_flashcard does on Flashcard MCP

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

WHY IT NEEDS A POLICY

Why create_flashcard needs a policy

This tool creates new flashcard records within a project, which is a Write operation (reversible data creation). The blast radius is low because creating flashcards cannot compromise system security, financial data, or cause significant harm. The operation is easily reversible via delete_flashcard. The confidence is high because the description unambiguously indicates a create/add operation.

From the tool's definition Tool description states 'Create a new flashcard in a project' — explicit creation operation that adds new data to the system reversibly.
