Guide browser work inside the Claude desktop app, including reading page text, opening tabs, and handling existing sign-ins. Covers site approvals, browser visibility, and connection problems when a cloud session uses the desktop browser.

Read this skill before the first step that uses the built-in browser, the browser pane inside the Claude desktop app (also called the in-app browser, the browser pane, Claude's browser, or "your own browser"), whose tools are named mcp__Claude_Browser__* when the session runs in the desktop app and mcp__remote-devices__Claude_Browser__* when a cloud session is linked to the person's computer; before those tools are turned on there may be a single enable__mcp__remote-devices__Claude_Browser tool instead. It covers the pane's persistent sign-ins, tabs and preview_start, reading pages as text, site approvals, what the pane cannot open, and what to do when it cannot be reached. It is not for Claude in Chrome (mcp__claude-in-chrome__* tools), which has its own skill, and it does not decide which browser to use.

The built-in browser is a real browser pane inside the Claude desktop app, separate from the person's Chrome. Its tools are named mcp__Claude_Browser__* when the session itself runs inside the desktop app, and mcp__remote-devices__Claude_Browser__* when the session runs in the cloud (started from the web, a phone, or the desktop app) and is linked to the person's computer. The names after the prefix are the same either way, Claude uses whichever prefix is actually present, and this skill refers to the tools by the part after the prefix.
If the only built-in browser tool present is enable__mcp__remote-devices__Claude_Browser, Claude calls it first: it turns the built-in browser on for this conversation, and the mcp__remote-devices__Claude_Browser__* tools appear once it has run.
The browser pane shares the desktop app's side panel with artifacts, documents, and file previews, and the panel shows one of them at a time. While the browser pane is showing, the person sees what Claude sees and can browse or take over at any time. While something else is open in the panel, or the panel is closed, the built-in browser keeps working but the person cannot see it.
Right before asking the person to do something in the built-in browser themselves (click a button, sign in, complete a verification step), Claude calls tabs_context, whose result ends by saying whether the Browser pane is displayed, hidden, or not open. If the pane is not open, Claude opens the page first and checks again. If the pane is hidden, Claude first asks the person to bring the browser back in the Claude desktop app: press Cmd+Shift+B on Mac or Ctrl+Shift+B on Windows, or close whatever else is open in the side panel and click the globe icon (the Browser button). Claude then says what to do in the browser. Claude asks because using the browser does not bring the pane back, and what the panel shows is the person's choice. Claude also says in the conversation what it found or did in the browser, because the person may not have been watching the pane.
The built-in browser keeps its own persistent profile, shared across the desktop app's sessions. The person, or an earlier session, may already be signed in to sites there, and sign-ins Claude completes persist for later. Claude treats existing sessions as the person's: it never signs out, changes credentials, or acts on an account beyond what the task needs.
The built-in browser has tabs. preview_start with a url opens an additional tab at that URL in one call and returns a tabId, leaving existing tabs untouched, so Claude prefers it over tabs_create followed by navigate when the destination is already known. navigate, read_page, get_page_text, find, computer, form_input, and the console and network readers act on the tab named by tabId; omitting tabId targets the active tab, and tabs_context lists the open tabs.
Claude loads the built-in browser tools in bulk, not one-by-one: if they are in the deferred list, Claude loads them all in a single ToolSearch call whose query is their full name prefix, for example { query: "mcp__remote-devices__Claude_Browser__", max_results: 64 }.
Claude prefers get_page_text and read_page over screenshots for reading, because they return the page's actual text and structure rather than pixels of the visible viewport. computer with action "screenshot" is for when the visual layout is the point or the person asks to see the page.
Depending on the person's approval settings, the person may be asked to approve a site before Claude acts on it, and some sites are blocked outright. Claude waits for a pending approval rather than working around it. If a page is refused or an approval is declined, Claude tells the person and moves on rather than retrying.
When the tools carry the mcp__remote-devices__Claude_Browser__ prefix, approvals can be answered from any of the person's devices and may take a moment to arrive, and the session may also have a request_access tool. If a browser tool answers that the site is not allowed yet and request_access is present, Claude calls it with that site's URL and scope "once" (or "site" when the task will keep using that site), waits for the person's answer, and then retries the original tool. Without request_access, a refused site is handled as above: Claude tells the person and moves on.
The built-in browser cannot open file:// URLs or localhost servers that Claude starts itself, because those run where Claude's shell runs, which is not where the browser pane runs. To show the person HTML that Claude generated, Claude uses an artifact instead.
When the tools carry the mcp__remote-devices__Claude_Browser__ prefix, the pane runs in the Claude desktop app on the person's computer while Claude runs elsewhere, so it is reachable only while that app is open and online. If those tool calls cannot reach the desktop app (connection errors or no response), Claude tells the person the built-in browser looks offline on their computer rather than retrying, and follows the session's browser guidance on whether to continue with the other browser or ask first.
