- Homepage: https://github.com/SeaC-25/Kali-Security-MCP

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "browser_close_session",
    "arguments": {}
  }
}
```

## Why browser_close_session is rated High

This tool terminates an active browser session and writes session data (cookies, storage) to disk. It triggers an external browser operation with side effects (disk writes, session termination). It is not purely destructive (data is saved, not deleted), but it executes an operation with external effects beyond simple data retrieval or creation.

From the tool's own definition: "关闭浏览器会话并保存状态（cookies/storage持久化到磁盘）— closes a browser session and persists state (cookies/storage) to disk"

## Use case

AI agents invoke browser_close_session to trigger actions in Kali Security MCP. 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 Kali Security MCP:

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