WHAT IT DOES

What remove_tags_from_cards does on Anki MCP Data Bridge

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

WHY IT NEEDS A POLICY

Why remove_tags_from_cards needs a policy

Removing tags from cards modifies existing data (the tags associated with cards), but it is a reversible operation since tags can be re-added. This falls under Write rather than Destructive because the cards themselves are not deleted and the tag modification can be undone. The blast radius is medium since it could affect many cards at once if misused.
