THE RISK

Medium Risk

Why create_note_type needs a policy

This tool creates a new note type, which is a reversible write operation that adds a new template/schema to the Anki system. It doesn't execute arbitrary code, delete data irreversibly, or move money. The medium severity reflects that creating unwanted note types could clutter the Anki database but can be undone by deletion.

From the tool's definition Tool name 'create_note_type' and description 'Create a new note type' indicate creation of a new data structure in Anki's note type system.

POLICY

How to control create_note_type

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_note_type": {
      "limits": [
        {
          "counter": "create_note_type_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_note_type 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.

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

Questions about create_note_type

What does the create_note_type tool do? +

How do I enforce a policy on create_note_type? +

Register the Anki MCP Server MCP server in PolicyLayer and add a rule for create_note_type: 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 MCP Server. Nothing to install.

What risk level is create_note_type? +

create_note_type is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_note_type? +

Yes. Add a rate_limit block to the create_note_type 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.

How do I block create_note_type completely? +

Set action: deny in the PolicyLayer policy for create_note_type. 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.

What MCP server provides create_note_type? +

create_note_type is provided by the Anki MCP Server MCP server (nailuogg/anki-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Anki MCP Server tool call.

Start from Anki MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
