# start_chrome_and_connect Start Chrome with debugging, connect, and navigate to URL in one step. Convenience function that combines browser startup, connection establishment, and navigation into a single operation. Equivalent to calling start_chrome with auto_connect=True and a URL parameter. This function is ideal for quick browser automation tasks where you need to get Chrome running and navigate to a specific page without manual connection management. Args: url: Target URL to navigate to after Chrome startup. Must be a valid URL that Chrome can load. port: TCP port for Chrome remote debugging server (default: 9222). Must be available or already in use by Chrome. headless: Whether to run Chrome in headless mode without GUI. Particularly useful for automated testing scenarios. chrome_path: Custom path to Chrome executable. If not provided, uses automatic platform-specific detection. Returns: Combined status dictionary containing startup, connection, and navigation results. Includes all fields from start_chrome plus navigation status. Note: This is a convenience wrapper around start_chrome with auto_connect=True. For more granular control over the startup process, use start_chrome directly.

While it doesn't directly execute code itself, it establishes a debugging connection that enables the broader set of Execute capabilities on this server (execute_javascript, evaluate_in_all_frames). From the tool's own definition: "Tool description states it 'Start Chrome with debugging, connect, and navigate to URL in one step' and 'combines browser startup, connection establishment, and navigation into a single operation.' The sibling tools include 'execute_javascript' and…" ## Use case AI agents invoke start_chrome_and_connect to trigger actions in Chrome Devtools. 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**.
