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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {

    "arguments": {
      "value": "<value>",
      "selector": "<selector>"
    }
  }
}

## Why browser_type is rated High

Browser typing tools typically simulate keyboard input into web elements, which can trigger form submissions, searches, or other UI interactions. This falls under Execute as it triggers external browser operations. Empty description lowers confidence, but the name pattern in a browser automation context strongly suggests interactive input execution.

From the tool's own definition: "Tool name 'browser_type' suggests typing text into browser input fields, which is a browser action/interaction. Description is empty, providing no additional context."

## Use case

AI agents invoke browser_type to trigger actions in Looking Glass. 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 Looking Glass:

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