`close_page` — Closes the page by its index. The last open page cannot be closed. - `uninstall_extension` — Uninstalls a Chrome extension by its ID. - `click` — Clicks on the provided element - `click_at` — Clicks at the provided coordinates - `drag` — Drag an element onto another element - `emulate` — Emulates various features on the selected page. - `evaluate` — Evaluates a JavaScript script - `evaluate_script` — Evaluate a JavaScript function inside the currently selected page${cliArgs?.categoryExtensions ? - `execute_3p_developer_tool` — Executes a tool exposed by the page. - `execute_webmcp_tool` — Executes a WebMCP tool exposed by the page. - `fill_form` — Fill out multiple form elements (inputs, selects, checkboxes, radios) at once. ALWAYS prefer this tool over multiple individual - `handle_dialog` — If a browser dialog was opened, use this command to handle it - `hover` — Hover over the provided element - `install_extension` — Installs a Chrome extension from the given path. - `lighthouse_audit` — Get Lighthouse score and reports for accessibility, SEO, best practices, and agentic browsing. This excludes performance. For performance audits, run ${startTrace.name} - `navigate` — Loads a URL - `performance_start_trace` — Start a performance trace on the selected webpage. Use to find frontend performance issues, Core Web Vitals (LCP, INP, CLS), and improve page load speed. - `performance_stop_trace` — Stop the active performance trace recording on the selected webpage. - `press_key` — Press a key or key combination. Use this when other input methods like fill() cannot be used (e.g., keyboard shortcuts, navigation keys, or special key combinations). - `reload_extension` — Reloads an unpacked Chrome extension by its ID. - `resize_page` — Resizes the selected page - `screencast_stop` — Stops the active screencast recording on the selected page. - `select_page` — Select a page as a context for future tool calls. - `trigger_extension_action` — Triggers the default action of an extension by its ID. - `type_text` — Type text using keyboard into a previously focused input - `wait_for` — Wait for the specified text to appear on the selected page. - `compare_heapsnapshots` — Loads two memory heapsnapshots and returns the comparison. If classIndex is provided, returns detailed diff for that class, otherwise returns summary diff. - `get_console_message` — Gets a console message by its ID. You can get all messages by calling ${LIST_CONSOLE_MESSAGES_TOOL_NAME}. - `get_heapsnapshot_class_nodes` — Loads a memory heapsnapshot and returns instances of a specific class with their IDs. - `get_heapsnapshot_details` — Loads a memory heapsnapshot and returns all available information including statistics, static data, and aggregated node information. Supports pagination for aggregates. - `get_heapsnapshot_dominators` — Loads a memory heapsnapshot and returns the dominator chain for a specific node ID. This helps to identify which objects are keeping the target node alive. - `get_heapsnapshot_duplicate_strings` — Loads a memory heapsnapshot and returns duplicate strings grouped by their value. - `get_heapsnapshot_edges` — Loads a memory heapsnapshot and returns outgoing edges (references) for a specific node ID. - `get_heapsnapshot_retainers` — Loads a memory heapsnapshot and returns retainers for a specific node ID. - `get_heapsnapshot_retaining_paths` — Loads a memory heapsnapshot and returns retaining paths for a specific node ID. This helps to understand why a node is not being garbage collected. - `get_heapsnapshot_summary` — Loads a memory heapsnapshot and returns snapshot summary stats. - `get_network_request` — Gets a network request by an optional reqid, if omitted returns the currently selected request in the DevTools Network panel. - `get_tab_id` — Get the tab ID of the page - `list_3p_developer_tools` — Lists all third-party developer tools the page exposes for providing runtime information. Third-party developer tools can be called via the - `list_extensions` — Lists all the Chrome extensions installed in the browser.
