WHAT IT DOES

What store_media_file does on Anki

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

RISK

Why store_media_file is rated Medium

The tool stores media files, which creates new data in Anki's media collection—a reversible write operation. Without a description, confidence is reduced, but the name and context (Anki flashcard integration) strongly suggest file creation/storage rather than Read, Execute, or destructive operations. Medium severity because misuse could flood storage or corrupt media references, but effects are typically reversible.

From the tool's definition Tool name 'store_media_file' indicates it writes/persists media content. Description is empty, limiting confidence.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs store_media_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Anki, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For store_media_file, this is the rule to start with:

store_media_file Rate-limited

store_media_file stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
