Chrome Devtools

Uses Chrome DevTools via MCP for efficient debugging, troubleshooting and browser automation. Use when debugging web pages, automating browser interactions, analyzing performance, or inspecting network requests. This skill does not apply to `--slim` mode (MCP configuration).

Core Concepts

Browser lifecycle: Browser starts automatically on first tool call using a persistent Chrome profile. Configure via CLI args in the MCP server configuration: npx chrome-devtools-mcp@latest --help.

Page selection: Tools operate on the currently selected page. Use list_pages to see available pages, then select_page to switch context.

Element interaction: Use take_snapshot to get page structure with element uids. Each element has a unique uid for interaction. If an element isn't found, take a fresh snapshot - the element may have been removed or the page changed.

Workflow Patterns

Before interacting with a page

Navigate: navigate_page or new_page
Wait: wait_for to ensure content is loaded if you know what you look for.
Snapshot: take_snapshot to understand page structure
Interact: Use element uids from snapshot for click, fill, etc.

Efficient data retrieval

Use filePath parameter for large outputs (screenshots, snapshots, traces)
Use pagination (pageIdx, pageSize) and filtering (types) to minimize data
Set includeSnapshot: false on input actions unless you need updated page state

Tool selection

Automation/interaction: take_snapshot (text-based, faster, better for automation)
Visual inspection: take_screenshot (when user needs to see visual state)
Additional details: evaluate_script for data not in accessibility tree

Parallel execution

You can send multiple tool calls in parallel, but maintain correct order: navigate → wait → snapshot → interact.

Troubleshooting

Configure via CLI args in the MCP server configuration: `npx chrome-devtools-mcp@latest --help`. **Page selection**: Tools operate on the currently selected page. Use `list_pages` to see available pages, then `select_page` to switch context. **Element interaction**: Use `take_snapshot` to get page structure with element `uid`s. Each element has a unique `uid` for interaction. If an element isn't found, take a fresh snapshot - the element may have been removed or the page changed. ## Workflow Patterns ### Before interacting with a page 1. Navigate: `navigate_page` or `new_page` 2. Wait: `wait_for` to ensure content is loaded if you know what you look for. 3. Snapshot: `take_snapshot` to understand page structure 4. Interact: Use element `uid`s from snapshot for `click`, `fill`, etc. ### Efficient data retrieval - Use `filePath` parameter for large outputs (screenshots, snapshots, traces) - Use pagination (`pageIdx`, `pageSize`) and filtering (`types`) to minimize data - Set `includeSnapshot: false` on input actions unless you need updated page state ### Tool selection - **Automation/interaction**: `take_snapshot` (text-based, faster, better for automation) - **Visual inspection**: `take_screenshot` (when user needs to see visual state) - **Additional details**: `evaluate_script` for data not in accessibility tree ### Parallel execution You can send multiple tool calls in parallel, but maintain correct order: navigate → wait → snapshot → interact. ## Troubleshooting If `chrome-devtools-mcp` is insufficient, guide users to use Chrome DevTools UI: - https://developer.chrome.com/docs/devtools - https://developer.chrome.com/docs/devtools/ai-assistance If there are errors launching `chrome-devtools-mcp` or Chrome, refer to https://github.com/ChromeDevTools/chrome-devtools-mcp/blob/main/docs/troubleshooting.md.
