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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "deploy-percentage",
    "arguments": {
      "percentage": 0
    }
  }
}

## Why deploy-percentage is rated High

This tool triggers an external operation (Chrome Web Store staged rollout percentage change) whose effects depend on arguments (the percentage value). While it modifies deployment state, it is not strictly destructive (reversible via lower percentage) and not financial. It is Execute because it commits a concrete action to production infrastructure affecting end-user availability.

From the tool's own definition: "Tool name 'deploy-percentage' and description 'Set the published deploy percentage for staged rollout on Chrome Web Store' indicates it executes a deployment action that changes the live distribution of an extension to real users."

## Use case

AI agents invoke deploy-percentage to trigger actions in Cws. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## 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": {
    "deploy-percentage": {
      "limits": [
        {
          "counter": "deploy-percentage_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
