How can I access Helmet Logs?
To access Helmet Logs enable the Debug mode on the Helmet Firewall settings page. Then enter the Helmet Logs page address:
helmet://inspect/ and navigate on helmet://. You can also navigate on all Helmet Debug pages on helmet://helmet-urls.How Helmet handles MCP connection?
To let your AI agent gain control over a Helmet browser instance you should configure your MCP profile to use:
"chromeArg", with the following Helmet arguments: --helmet-enable-debug and --remote-debugging-pipe, so that Helmet allows the AI agent to establish the MCP connection using the inherited FD3/FD4 pipe pair.Note: Use MCP carefully.
