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

  "method": "tools/call",
  "params": {
    "name": "cancel",
    "arguments": {}

## Why cancel is rated Medium

Cancelling a pending submission reverts/stops an in-progress action (a submission under review) rather than deleting data permanently. This is a reversible modification of state — the extension still exists and can be resubmitted — making Write the most appropriate category. It is not Destructive because no data is permanently deleted.

From the tool's own definition: "Cancel a pending submission on Chrome Web Store. Can be used to cancel an item currently in review."

## Use case

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

## Recommended policy (PolicyLayer)

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

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