Why deckNames needs a policy

This tool retrieves existing deck names from the Anki collection without creating, modifying, deleting, or executing any operations. It is a simple query operation with no side effects, fitting the Read category. Severity is low because access to deck names poses minimal security risk—it is metadata about the user's study structure with no sensitive personal data, financial implications, or destructive capabilities.

From the tool's definition Tool name is 'deckNames' and description states it 'Gets the complete list of deck names' and 'Returns a list of deck names.' The verb 'Gets' and the read-only nature of returning a list indicate data retrieval with no modification or side effects.

How to control deckNames

PolicyLayer is an MCP gateway — it sits between your AI agents and Anki, and nothing reaches the server without passing your rules. This is the rule we recommend for deckNames:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "deckNames": {}
  }
}

deckNames is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Anki — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
