What's New

🎉 New Tools

  • browser_webmcp_list / browser_webmcp_call — List and call the tools a page registers through the WebMCP API, letting the page do the work instead of driving its UI. When a page has WebMCP tools, the page status reports how many are available (#42613). WebMCP is experimental, see WebMCP in Chrome for how to enable it.

Other Changes

  • New --profile-dir-name <name> option (env PLAYWRIGHT_MCP_PROFILE_DIR_NAME) selects the Chrome profile to connect to in extension mode when the extension is installed in several profiles, for example "Profile 1" (#42527)
  • Headless browsers launched by the server are now closed after one hour without tool calls; the next tool call launches a new one. Use --idle-timeout <ms> (config timeouts.idle, env PLAYWRIGHT_MCP_IDLE_TIMEOUT) to change the timeout, 0 disables it. Headed and attached browsers are not closed unless a timeout is set explicitly (#42663, #42676)
  • --image-responses accepts only: a response that carries an image consists of the image parts alone, without the text part (#42672)

Bug Fixes

  • browser_close returns an error when the browser context is shared (--shared-browser-context) instead of breaking the calling client's session. This supersedes the v0.0.80 change that dropped the backend after browser_close (#42495)
  • With --shared-browser-context, browser_start_recording / browser_stop_recording (opt-in via --caps=devtools) keep each client's recording separate instead of delivering one client's recorded actions to another (#42622, #42627)
  • The file access check follows symlinks, so a symlink inside the workspace can no longer be used to read or write files outside the allowed roots (#42628)
  • Explicitly named output files in a nested directory (e.g. sub/shot.png) no longer fail with ENOENT; browser_file_upload and browser_drop resolve relative paths against the workspace root (#42540)
  • In extension mode with PLAYWRIGHT_MCP_EXTENSION_TOKEN set, a connection that never completes (e.g. the token belongs to another Chrome profile) now fails after 30 seconds with a hint instead of hanging the tool call forever (#42525)
  • Disable the Chromium sandbox by default on Linux for the bundled Chromium build, which lacks the setuid sandbox helper (#42490)

## What's New

### 🎉 New Tools

- **`browser_webmcp_list` / `browser_webmcp_call`** — List and call the
tools a page registers through the
[WebMCP](https://webmachinelearning.github.io/webmcp/) API, letting the
page do the work instead of driving its UI. When a page has WebMCP
tools, the page status reports how many are available
([#42613](microsoft/playwright#42613)). WebMCP
is experimental, see [WebMCP in
Chrome](https://developer.chrome.com/docs/ai/webmcp) for how to enable
it.

### Other Changes

- New `--profile-dir-name <name>` option (env
`PLAYWRIGHT_MCP_PROFILE_DIR_NAME`) selects the Chrome profile to connect
to in extension mode when the extension is installed in several
profiles, for example `"Profile 1"`
([#42527](microsoft/playwright#42527))
- Headless browsers launched by the server are now closed after one hour
without tool calls; the next tool call launches a new one. Use
`--idle-timeout <ms>` (config `timeouts.idle`, env
`PLAYWRIGHT_MCP_IDLE_TIMEOUT`) to change the timeout, `0` disables it.
Headed and attached browsers are not closed unless a timeout is set
explicitly
([#42663](microsoft/playwright#42663),
[#42676](microsoft/playwright#42676))
- `--image-responses` accepts `only`: a response that carries an image
consists of the image parts alone, without the text part
([#42672](microsoft/playwright#42672))

## Bug Fixes

- `browser_close` returns an error when the browser context is shared
(`--shared-browser-context`) instead of breaking the calling client's
session. This supersedes the v0.0.80 change that dropped the backend
after `browser_close`
([#42495](microsoft/playwright#42495))
- With `--shared-browser-context`, `browser_start_recording` /
`browser_stop_recording` (opt-in via `--caps=devtools`) keep each
client's recording separate instead of delivering one client's recorded
actions to another
([#42622](microsoft/playwright#42622),
[#42627](microsoft/playwright#42627))
- The file access check follows symlinks, so a symlink inside the
workspace can no longer be used to read or write files outside the
allowed roots
([#42628](microsoft/playwright#42628))
- Explicitly named output files in a nested directory (e.g.
`sub/shot.png`) no longer fail with `ENOENT`; `browser_file_upload` and
`browser_drop` resolve relative paths against the workspace root
([#42540](microsoft/playwright#42540))
- In extension mode with `PLAYWRIGHT_MCP_EXTENSION_TOKEN` set, a
connection that never completes (e.g. the token belongs to another
Chrome profile) now fails after 30 seconds with a hint instead of
hanging the tool call forever
([#42525](microsoft/playwright#42525))
- Disable the Chromium sandbox by default on Linux for the bundled
Chromium build, which lacks the setuid sandbox helper
