addCardsBatch · Anki MCP Server MCP: Risk & Policy

WHAT IT DOES

What addCardsBatch does on Anki MCP Server

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

WHY IT NEEDS A POLICY

Why addCardsBatch needs a policy

This tool creates new flashcard entries in an Anki deck, which is reversible (cards can be deleted). It does not execute code, destroy data irreversibly, or move money. Batch creation of cards is a write operation with moderate blast radius—incorrect bulk additions could clutter a deck but remain recoverable. Confidence is high as the name and description clearly indicate card creation/addition.

From the tool's definition Tool name 'addCardsBatch' and description 'Add multiple cards to a deck in batch' indicate creation of multiple data records in the Anki flashcard system.
