Are you @ChromeDevTools?Claim it, and your coding agent keeps it current with each release
Automate Chrome, inspect web pages and network traffic, and diagnose performance and memory problems from a coding agent.
What you can do with Chrome DevTools for agents
Open, select, close and navigate Chrome tabs.
Good to know
The final open page cannot be closed.
Test pages with CPU throttling, network throttling and different viewport sizes.
Good to know
Emulation affects the controlled browser page.
Record browser performance traces and inspect performance insights.
Good to know
Trace collection requires a running Chrome page.
List browser network requests and inspect request details.
Good to know
History covers up to three navigations and 1,000 requests per navigation.
Inspect browser console messages to diagnose page errors.
Good to know
Up to three navigations are retained, with 10,000 console messages per navigation.
Capture screenshots and accessibility-tree snapshots of web pages.
Good to know
Snapshots expose page content to the connected MCP client.
Evaluate JavaScript functions in a browser page.
Good to know
Returned values must be JSON-serializable.
Show all 28
Launch a dedicated Chrome instance or connect to a running debuggable browser.
Good to know
Auto-connect requires locally running Chrome 144+, remote debugging enabled and user approval.
Limit the tools exposed to an MCP client by category.
Good to know
Category flags control emulation, performance and network tools.
Save a JavaScript heap snapshot for memory investigation.
Good to know
Requires a Chrome page and a local output path.
Navigate, evaluate scripts and take screenshots with a three-tool browser interface.
Good to know
`--slim` exposes only navigation, script execution and screenshots.
Test separate browser sessions with isolated cookies and storage.
Good to know
Pages with the same named browser context share storage; different contexts are isolated.
Run Lighthouse audits for accessibility, best practices and SEO.
Good to know
Runs against a browser page; use performance tracing for performance investigation.
Install, list, reload, trigger and uninstall unpacked Chrome extensions.
Good to know
Enable `--category-extensions`; documentation requires a pipe connection rather than auto-connect, browser URL or WebSocket.
Allow or block browser requests using URL patterns.
Good to know
`--allowed-url-pattern` requires Chrome 149+; patterns apply to browser traffic, including navigation and subresources.
Install, launch, uninstall and inspect OS integration state for Progressive Web Apps.
Good to know
Enable `--category-pwa`; requires a pipe connection. Installs default to browser mode unless standalone is requested.
Choose allowed filesystem directories for browser tools.
Good to know
Use repeatable `--filesystem-root` or `--workspace`; the default root is the OS temp directory.
Disable JavaScript evaluation tools and script-based navigation in browser automation.
Good to know
`--no-javascript-evaluation` disables evaluation and init scripts and rejects javascript, data and vbscript URL navigation.
Inspect matched CSS rules and cascade information for a page element.
Good to know
Requires an element UID from `take_snapshot`; returns 10 rules per page by default.
Load browser-tool settings from a JSON configuration file.
Good to know
Pass the file path with `--config`.
Record a screencast of a Chrome page.
Good to know
Experimental; requires `--experimental-screencast` and ffmpeg on the server PATH.
Automate and inspect Chrome from the command line without an MCP client.
Good to know
Experimental `chrome-devtools` CLI; requires the npm package and Chrome.
Route browser actions to explicit page IDs for concurrent sessions.
Good to know
Page-scoped calls require `pageId` by default; disable routing to use the selected page.
List and execute WebMCP tools exposed by a page.
Good to know
Requires `--category-experimental-webmcp`, Chrome 150+ and `--enable-features=WebMCP`.
Click a browser page at screen coordinates.
Good to know
Experimental; enable `--experimental-vision`. Coordinate accuracy depends on the calling model.
List and execute third-party developer tools exposed by a page.
Good to know
Experimental; enable `--category-experimental-third-party`; the inspected page must expose tools.
Inspect heap statistics, class instances and retainers to investigate memory use.
Good to know
Requires `--memory-debugging` and heap snapshot files.
Before you upgrade Chrome DevTools for agents
Newest firstConsole retention is capped at 10,000 messages per navigation; same-document navigation now preserves console history.
Puppeteer logs are no longer written to a file unless requested.
The CLI enables `--allow-unrestricted-paths` by default.
Show 46 older
The default trace buffer is increased to 1.2 GB to match DevTools.
Chrome WebUI targets are filtered out by default.
Supply positive finite viewport dimensions and device-pixel ratio, latitude within -90..90 and longitude within -180..180; invalid values are rejected.
Supply `pageId` on page-scoped tools by default. Replace `--experimental-page-id-routing` with `--page-id-routing`; use `--no-page-id-routing` for selected-page behavior.
Replace `upload_file.filePath` with the `filePaths` array, even for one file; paths refer to the browser's machine.
Use filenames ending in `.heapsnapshot` or `.heaptimeline` when loading heap snapshots; other extensions are now rejected.
CLI errors print the error message alone instead of JSON; startup no longer imposes headless/isolated defaults when connecting to an existing browser.
Use `NODE_DEBUG` instead of `DEBUG` to enable verbose diagnostic logging.
Network history is capped at 1,000 requests per navigation; older retained requests are discarded.
Use an empty session ID or one containing only hexadecimal characters (`0-9`, `a-f`, `A-F`) and hyphens; other custom session IDs are rejected.
Use Chrome 150+ and `--enable-features=WebMCP` for the experimental WebMCP category.
Without negotiated MCP roots, write files to the OS temp directory or configure roots. Trusted local clients needing unrestricted paths can use `--allow-unrestricted-paths`.
Replace `handleBeforeUnload: decline` with `handleBeforeUnload: dismiss` in navigation calls.
Compressed trace filenames ending in `.gz` keep that extension instead of forcing `.json.gz`.
`list_pages` includes each page's title.
Replace Chrome's `WebMCPTesting` feature flag with `WebMCP`, keeping `DevToolsWebMCPSupport` for this release.
With `--experimental-page-id-routing`, supply `pageId` for page-scoped calls; CLI calls place required `pageId` first.
Replace `take_memory_snapshot` calls with `take_heapsnapshot`.
Use `get_heapsnapshot_details`, `get_heapsnapshot_summary`, `get_heapsnapshot_class_nodes` and `get_heapsnapshot_retainers` instead of the older memory names; class lookup now takes `id`, not `uid`.
Server shutdown on stdin EOF or termination signals closes the browser cleanly.
Keep file-tool paths within MCP client roots or the OS temp directory; paths outside these locations are rejected when the client supplies roots.
Replace `--experimental-webmcp` with `--category-experimental-webmcp`.
Identical consecutive console messages are grouped in `list_console_messages`.
Actions that cause navigation report the resulting URL.
Use a comma-separated `latitude,longitude` string for geolocation instead of the earlier x-separated string.
Tool calls now report unknown arguments; token estimates are no longer included in responses.
Dialogs during script evaluation are automatically accepted by default; `dialogAction` can dismiss them or supply prompt text.
The binaries periodically check the npm registry for updates; set `CHROME_DEVTOOLS_MCP_NO_UPDATE_CHECKS` to disable checks.
File outputs now enforce their expected extensions, which can change the saved filename.
Lighthouse is marked non-read-only, so clients enforcing read-only mode may exclude it.
Memory snapshot capture is marked non-read-only, so clients enforcing read-only mode may exclude it.
Use viewport strings such as `800x600x2,mobile,touch` and geolocation as `latitudexlongitude`; omit network settings to clear throttling instead of using `No emulation`.
`performance_start_trace` now defaults `reload` and `autoStop` to true when omitted.
Do not combine `--categoryExtensions` with `--autoConnect`; the options are now mutually exclusive.
Input tools omit snapshots unless `includeSnapshot` is true; `type_text` adds direct typing and `fill` no longer accidentally types extra text.
Pass a non-empty array to `wait_for.text` instead of a string; it resolves when any text appears. New pages can also open in the background.
Trace summaries fetch CrUX field data by sending trace URLs to Google by default; disable with `--no-performance-crux`.
Usage statistics are enabled by default. Opt out with `--no-usage-statistics`; setting `CI` or `CHROME_DEVTOOLS_MCP_NO_USAGE_STATISTICS` also disables collection.
Auto-connect is documented for Chrome 144+ with remote debugging enabled.
Replace `pageIdx` with `pageId` in `select_page` and `close_page`, using IDs returned by `list_pages`.
DevTools issues are included in console tools again.
`list_console_messages` no longer includes DevTools issues in this release.
Replace `navigate_page_history` with `navigate_page` and `type: back` or `forward`; `reload` and `ignoreCache` are also available.
Replace `emulate_cpu` and `emulate_network` with `emulate`, using `cpuThrottlingRate` and `networkConditions`.
Supply `insightSetId` from the trace's available insight sets when calling `performance_analyze_insight`.
Replace the `url` argument to `get_network_request` with the numeric `reqid` from `list_network_requests`; preserved requests can span three navigations.
