browser_get_config
AI agents call browser_get_config to retrieve information from Playwright MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to query or retrieve browser configuration settings rather than modify state, execute code, or perform destructive actions. Even if it exposes sensitive configuration details, the primary function is read-only retrieval with no direct execution or mutation capability.
