What import_package does on Anki
AI agents use import_package 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.
Why import_package is rated Medium
Import operations typically create or add data reversibly. The tool fits the Write category (creates/modifies data) rather than Execute, as it appears domain-specific to Anki package imports rather than arbitrary code execution. Severity is medium because importing malicious or bulk packages could corrupt Anki libraries, but the damage is reversible (unlike Destructive operations).
From the tool's definition Tool name 'import_package' suggests importing data into Anki. Given the server context (flashcard management), this likely creates or modifies Anki content (decks/notes).
Attacks that exploit this kind of access
The rule that runs import_package 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 import_package, this is the rule to start with:
import_package 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Anki, apply this rule, and every import_package call is checked against it from then on.
Questions about import_package
import_package is a write tool on the Anki MCP server. It is categorised as a Write tool in the Anki MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Anki MCP server in PolicyLayer and add a rule for import_package: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Anki. Nothing to install.
import_package is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the import_package rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for import_package. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
import_package is provided by the Anki MCP server (@arielbk/anki-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
