|
description: Use this 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
|
|
```
|
|
|
|

## Experimental Features
|
|
|
|
Experimental tools are disabled by default. Enable them with the corresponding flag during `start`.
|
|

|
```bash
|
|
chrome-devtools click_at 100 200 # Clicks at the provided coordinates (requires --experimentalVision=true)
|
|
chrome-devtools screencast_start # Starts a screencast recording (requires --experimentalScreencast=true and ffmpeg)
|
|
chrome-devtools screencast_stop # Stops the active screencast
|
|
chrome-devtools list_webmcp_tools # List all WebMCP tools (requires --categoryExperimentalWebmcp=true)
|
|
```
|
|
|
|
## 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
|
|
```
