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

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

## Why browser_get_config is rated Low

The tool name suggests it retrieves browser configuration settings without modifying state. Based on naming convention and context from similar tools in the server (which include read operations like cookie_get and console_messages), this is classified as a Read operation with low blast radius—it merely exposes existing configuration data to the AI agent.

From the tool's own definition: "Tool name 'browser_get_config' indicates retrieval of configuration data. The pattern aligns with sibling tools like 'browser_cookie_get', 'browser_cookie_list', and 'browser_console_messages', which are read-only operations."

## Use case

AI agents call browser_get_config to retrieve information from Playwright MCP 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 Playwright MCP:

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