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

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

## Why get_all_cookies is rated Low

This tool retrieves and queries cookie data from the browser without modifying, deleting, or executing anything. It is a read-only operation. Severity is medium rather than low because cookies often contain sensitive authentication tokens, session identifiers, or personal data that could be misused if exposed to an untrusted AI agent, but the tool itself performs no destructive or operational actions.

From the tool's own definition: "Tool name is 'get_all_cookies' and description states 'Get all browser cookies' with 'Returns: List of all cookies with details'. This is a retrieval operation with no side effects."

## Use case

AI agents call get_all_cookies to retrieve information from Chrome Devtools without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Chrome Devtools:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_all_cookies": {}
  }
}
```
