AI agents call list_note_types to retrieve information from Anki without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and lists metadata about note types that already exist in the Anki system. It performs no create, update, delete, or execution operations. The blast radius of misuse is minimal — an AI agent querying this tool cannot harm data or trigger unwanted side effects. Classified as Read with low severity.
From the tool's definition Tool description states 'Return available Anki note types' — a retrieval operation with no modification or side effects. The verb 'Return' and action of listing/querying existing note types confirms this is a read-only operation.
Attacks that exploit this kind of access
Return available Anki note types with field and template summaries. It is categorised as a Read tool in the Anki MCP Server, which means it retrieves data without modifying state.
Register the Anki MCP server in PolicyLayer and add a rule for list_note_types: 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.
list_note_types is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_note_types 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 list_note_types. 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.
list_note_types is provided by the Anki MCP server (yama662607/anki-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
