chrome-devtools-cli: Скилл автоматизации задач в браузере

--- name: chrome-devtools-cli description: Use this to skill to write shell scripts or run shell commands to automate tasks in the browser or otherwise use Chrome DevTools via CLI. --- The `chrome-devtools-mcp` CLI lets you interact with the browser from your terminal. ## Setup _Note: If this is your very first time using the CLI, see [references/installation.md](references/installation.md) for setup. Installation is a one-time prerequisite and is **not** part of the regular AI workflow._ ## AI Workflow 1. **Execute**: Run tools directly (e.g., `chrome-devtools list_pages`). The background server starts implicitly; **do not** run `start`/`status`/`stop` before each use. 2. **Inspect**: Use `take_snapshot` to get an element `<uid>`. 3. **Act**: Use `click`, `fill`, etc. State persists across commands. Snapshot example: ``` uid=1_0 RootWebArea "Example Domain" url="https://example.com/" uid=1_1 heading "Example Domain" level="1" ``` ## Command Usage ```sh chrome-devtools <tool> [arguments] [flags] ``` Use `--help` on any command. Output defaults to Markdown, use `--output-format=json` for JSON. ## Input Automation (<uid> from snapshot) ```bash chrome-devtools take_snapshot --help # Help message for commands, works for any command. chrome-devtools take_snapshot # Take a text snapshot of the page to get UIDs for elements chrome-devtools click "id" # Clicks on the provided element chrome-devtools click "id" --dblClick true --includeSnapshot true # Double clicks and returns a snapshot chrome-devtools drag "src" "dst" # Drag an element onto another element chrome-devtools drag "src" "dst" --includeSnapshot true # Drag an element and return a snapshot chrome-devtools fill "id" "text" # Type text into an input or select an option chrome-devtools fill "id" "text" --includeSnapshot true # Fill an element and return a snapshot chrome-devtools handle_dialog accept # Handle a browser dialog chrome-devtools handle_dialog dismiss --promptText "hi" # Dismiss a dialog with prompt text chrome-devtools hover "id" # Hover over the provided element chrome-devtools hover "id" --includeSnapshot true # Hover over an element and return a snapshot chrome-devtools press_key "Enter" # Press a key or key combination chrome-devtools press_key "Control+A" --includeSnapshot true # Press a key and return a snapshot chrome-devtools type_text "hello" # Type text using keyboard into a focused input chrome-devtools type_text "hello" --submitKey "Enter" # Type text and press a submit key chrome-devtools upload_file "id" "file.txt" # Upload a file through a provided element chrome-devtools upload_file "id" "file.txt" --includeSnapshot true # Upload a file and return a snapshot ``` ## Navigation ```bash chrome-devtools close_page 1 # Closes the page by its index chrome-devtools list_pages # Get a list of pages open in the browser chrome-devtools navigate_page --url "https://example.com" # Navigates the currently selected page to a URL chrome-devtools navigate_page --type "reload" --ignoreCache true # Reload page ignoring cache chrome-devtools navigate_page --url "https://example.com" --timeout 5000 # Navigate with a timeout chrome-devtools navigate_page --handleBeforeUnload "accept" # Handle before unload dialog chrome-devtools navigate_page --type "back" --initScript "foo()" # Navigate back and run an init script chrome-devtools new_page "https://example.com" # Creates a new page chrome-devtools new_page "https://example.com" --background true --timeout 5000 # Create new page in background chrome-devtools new_page "https://example.com" --isolatedContext "ctx" # Create new page with isolated context chrome-devtools select_page 1 # Select a page as a context for future tool calls chrome-devtools select_page 1 --bringToFront true # Select a page and bring it to front ``` ## Emulation ```bash chrome-devtools emulate --networkConditions "Offline" # Emulate network conditions chrome-devtools emulate --cpuThrottlingRate 4 --geolocation "0,0" # Emulate CPU throttling and geolocation chrome-devtools emulate --colorScheme "dark" --viewport "1920x1080" # Emulate color scheme and viewport chrome-devtools emulate --userAgent "Mozilla/5.0..." # Emulate user agent chrome-devtools resize_page 1920 1080 # Resizes the selected page's window ``` ## Performance ```bash chrome-devtools performance_analyze_insight "1" "LCPBreakdown" # Get more details on a specific Performance Insight chrome-devtools performance_start_trace true false # Starts a performance trace recording chrome-devtools performance_start_trace true true --filePath t.gz # Start trace and save to a file chrome-devtools performance_stop_trace # Stops the active performance trace chrome-devtools performance_stop_trace --filePath "t.json" # Stop trace and save to a file chrome-devtools take_memory_snapshot "./snap.heapsnapshot" # Capture a memory heapsnapshot ``` ## Network ```bash chrome-devtools get_network_request # Get the currently selected network request chrome-devtools get_network_request --reqid 1 --requestFilePath req.md # Get request by id and save to file chrome-devtools get_network_request --responseFilePath res.md # Save response body to file chrome-devtools list_network_requests # List all network requests chrome-devtools list_network_requests --pageSize 50 --pageIdx 0 # List network requests with pagination chrome-devtools list_network_requests --resourceTypes Fetch # Filter requests by resource type chrome-devtools list_network_requests --includePreservedRequests true # Include preserved requests ``` ## Debugging & Inspection ```bash chrome-devtools evaluate_script "() => document.title" # Evaluate a JavaScript function on the page evaluate_script "(a) => a.innerText" --args 1_4 # Evaluate JS with UID arguments chrome-devtools get_console_message 1 # Gets a console message by its ID chrome-devtools lighthouse_audit --mode "navigation" # Run Lighthouse audit for navigation chrome-devtools lighthouse_audit --mode "snapshot" --device "mobile" # Run Lighthouse audit for a snapshot on mobile chrome-devtools lighthouse_audit --outputDirPath ./out # Run Lighthouse audit and save reports chrome-devtools list_console_messages # List all console messages chrome-devtools list_console_messages --pageSize 20 --pageIdx 1 # List console messages with pagination chrome-devtools list_console_messages --types error --types info # Filter console messages by type chrome-devtools list_console_messages --includePreservedMessages true # Include preserved messages chrome-devtools take_screenshot # Take a screenshot of the page viewport chrome-devtools take_screenshot --fullPage true --format "jpeg" --quality 80 # Take a full page screenshot as JPEG with quality chrome-devtools take_screenshot --uid "id" --filePath "s.png" # Take a screenshot of an element chrome-devtools take_snapshot # Take a text snapshot of the page from the a11y tree chrome-devtools take_snapshot --verbose true --filePath "s.txt" # Take a verbose snapshot and save to file ``` ## Service Management ```bash chrome-devtools start # Start or restart chrome-devtools-mcp chrome-devtools status # Checks if chrome-devtools-mcp is running chrome-devtools stop # Stop chrome-devtools-mcp if any ```
