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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "browser_click",
    "arguments": {
      "selector": "<selector>",
      "session_id": "<session_id>"
    }
  }

## Why browser_click is rated High

Clicking browser elements is an Execute-category action: it triggers external operations (form submissions, navigation, API calls, purchases, deletions) whose effects are wholly determined by the target element. An AI agent could misuse this to click confirmation buttons, submit forms, or trigger destructive/financial actions, making severity high.

From the tool's own definition: "'Click an element by CSS selector' and 'Wait for any animations/navigation to settle' — triggers UI interactions and browser navigation whose effects depend entirely on what element is clicked"

## Use case

AI agents invoke browser_click to trigger actions in Yaver. 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 Yaver:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_click": {
      "limits": [
        {
          "counter": "browser_click_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
