## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "create_deck",
    "arguments": {}

## Why create_deck is rated Medium

Creating a deck is a reversible modification operation—decks can be renamed, moved, or deleted without permanent loss if done promptly. It does not execute arbitrary code, delete data, or commit financial transactions. The action is idempotent (creating the same deck twice typically results in one deck) and non-destructive.

From the tool's own definition: "Tool name 'create_deck' indicates creation of a new deck entity in Anki. Empty description limits certainty, but context from sibling tools (add_note, add_notes, add_tags_to_notes) confirm this server performs data modification operations."

## Use case

AI agents use create_deck 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Anki:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_deck": {
      "limits": [
        {
          "counter": "create_deck_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
