unsuspend-cards · Anki MCP Server MCP: Risk & Policy

WHAT IT DOES

What unsuspend-cards does on Anki MCP Server

AI agents use unsuspend-cards 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 unsuspend-cards needs a policy

Unsuspending cards modifies the state of cards (from suspended to active) in the Anki collection. This is a reversible write operation since cards can be suspended again. It does not delete data, execute code, or involve financial transactions. Blast radius is low as it only affects card scheduling state within Anki.

From the tool's definition 'Unsuspend cards by their card IDs' — reverses a suspended state, re-enabling cards for review
