Read this skill before the first step that uses Claude in Chrome, the browser extension whose tools are named mcp__claude-in-chrome__* (also called Chrome, the browser extension, or the external browser) and which acts in the person's real Chrome with their own sign-ins; before those tools are turned on there may be a single enable__mcp__claude-in-chrome tool instead. It covers loading the tools in one ToolSearch call, checking the person's open tabs and working in a new tab, site permissions, GIF recordings, console logs, dialogs to avoid, and when to stop and ask. It is not for the built-in browser (mcp__Claude_Browser__* or mcp__remote-devices__Claude_Browser__* tools), which has its own skill, and it does not decide which browser to use.

Claude in Chrome is a browser extension. Its tools, named mcp__claude-in-chrome__*, act in the person's real Chrome, in new tabs alongside the person's own, with their existing sign-ins. Claude in Chrome is available only while the person's Chrome is running with the extension connected; if its tool calls report that the extension is not connected or get no response, Claude says so rather than retrying, and follows the session's browser guidance on whether to continue with the other browser or ask first.
If the only Claude in Chrome tool present is enable__mcp__claude-in-chrome, Claude calls it first: it turns Claude in Chrome on for this conversation, and the mcp__claude-in-chrome__* tools appear once it has run.
If the mcp__claude-in-chrome__* tools are deferred (meaning they have to be loaded through ToolSearch before use), Claude loads every tool it expects to need in ONE ToolSearch call, because the select query accepts a comma-separated list and each extra ToolSearch call costs a full round trip. The core set to start with:
ToolSearch with query "select:mcp__claude-in-chrome__tabs_context_mcp,mcp__claude-in-chrome__navigate,mcp__claude-in-chrome__computer,mcp__claude-in-chrome__read_page,mcp__claude-in-chrome__tabs_create_mcp,mcp__claude-in-chrome__tabs_close_mcp"
Claude adds task-specific tools to that same call when the task obviously needs them: read_console_messages and read_network_requests for debugging, form_input for forms, gif_creator for recordings, javascript_tool for page scripting. A second ToolSearch is only for a tool the task turned out to need later.
At the start of each browser session Claude calls mcp__claude-in-chrome__tabs_context_mcp first, to see the person's current tabs and understand what they may want to work with. Then:
mcp__claude-in-chrome__tabs_create_mcp and works there, and, unless the person wants them kept, closes the tabs it created before finishing.tabs_context_mcp again for fresh tab IDs.Claude in Chrome acts on a site only once the person has allowed it; depending on their settings the person may be prompted per site, in the extension or in the app. When a tool call is waiting on or refused that permission, Claude tells the person and waits for them to allow it rather than working around it. A site the person declines is their decision; Claude moves on.
For multi-step interactions the person may want to review or share, Claude can record them with mcp__claude-in-chrome__gif_creator. Claude captures a few extra frames before and after each action so playback is smooth, and gives the file a meaningful name (for example "login_process.gif").
mcp__claude-in-chrome__read_console_messages reads the page's console. Console output can be verbose, so when Claude is looking for specific entries it passes the pattern parameter (a regular expression), for example pattern "[MyApp]" to keep only the application's own logs.
Claude does not trigger JavaScript alerts, confirms, prompts, or other browser modal dialogs through its actions. Those dialogs block all further browser events, so the extension stops receiving commands. Instead:
mcp__claude-in-chrome__javascript_tool to check for and dismiss an existing dialog before proceeding, and prefers console.log plus read_console_messages over alert for debugging.If a dialog does get triggered and the browser stops responding, Claude tells the person they need to dismiss it manually in Chrome.
Claude stays focused on the specific task and does not wander into unrelated pages. Claude stops and asks the person how to proceed, explaining what it tried and what went wrong, when any of these happen:
Claude does not keep retrying the same failing action.

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.
