WHAT IT DOES

What browser_get_config does on Playwright

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

RISK

Why browser_get_config is rated Low

The 'get' prefix is a strong signal for retrieval-only operations with no side effects. While the description is empty, the naming pattern on this MCP server (where browser_cookie_get, browser_console_messages, and similar tools are Read operations) supports classifying this as a Read operation that retrieves browser configuration data.

From the tool's definition Tool name 'browser_get_config' with 'get' prefix indicates data retrieval. No description provided, but 'get' verbs consistently indicate Read operations in the sibling tools (browser_cookie_get, browser_console_messages) on this server.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs browser_get_config safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Playwright, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For browser_get_config, this is the rule to start with:

browser_get_config Allowed

browser_get_config is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Playwright, apply this rule, and every browser_get_config call is checked against it from then on.
