+**The web goes through the Chrome you already use.** The instructions the server sends with it now say that a step
+on the web uses the Chrome the person normally uses and is signed in to - not Safari, a new profile or another
+browser - and that the agent asks the person when it cannot tell which profile a task belongs to. This server does
+not see inside pages, so when Browser MCP's tools are in the session, the work inside the page is theirs, in the

+once that Browser MCP does that, with its install line, and never installs it itself. Test: `test/laering.mjs`

+The web: when a step needs a web page, use the Chrome the person normally uses -
+the profile whose windows are open, signed in to their accounts - not Safari, a
+new profile or another browser, unless they ask for one. \`computer_windows\`
+with app "Google Chrome" shows its windows. If you cannot tell which profile the
+task belongs to - windows from several are open, or the titles do not say - ask
+the person once with \`computer_ask_user\` - never pick one yourself. This server
+does not see inside pages, so if Browser MCP's tools (browser_*) are in this session, let them do
+the work inside the page - they work in the Chrome profile where their extension
+is installed, which browser_about names, so check it is that same profile - and
+keep this server for what is outside it: the file picker, an OS dialog, another
+app. If they are not here and the task is mostly inside web pages, tell the
+person once that Browser MCP does that (https://browsermcp.dev, by the same
+maker: a Chrome extension plus \`claude mcp add --scope user browser-mcp -- npx @agent360/browser-mcp@latest\`).
+Do not install it yourself.
