feat(mcp): allow saving browser_find results to a file by yury-s · Pull Request #42968 · microsoft/playwright

Yury Semikhatsky (yury-s) · 2026-09-28T16:00:24Z

Summary

Add filename option to browser_find and --filename to the CLI find command, so large result sets can be written to a file instead of the response.

Hi, I'm the Playwright bot and I took a first look at the CI failure here.

🟡 One failure, very likely unrelated, but not proven a flake on WebKit

The only failure is mcp/annotate.spec.ts:417 on Windows WebKit. This PR only changes browser_find, so it doesn't touch annotate. The same test flakes on other Windows browsers, including on main, but I found no earlier WebKit failure.

Details

Overall: this PR adds an option to save browser_find results to a file. It touches tools/backend/find.ts, the CLI daemon commands.ts, the skill doc and the find specs. None of that runs in the annotate/dashboard flow. The MCP run (36454676012) had 8789 tests pass and 1 fail.

Uncertain

[webkit] › mcp/annotate.spec.ts:417 › should cancel browser_annotate when the MCP client disconnects (mcp-windows-latest-webkit). The diff doesn't reach this test. The test-results DB (latest data from 2026-09-25) shows the same test flaking only on the Windows MCP bots, on runs this PR can't be responsible for:
- firefox: 7 of 705 runs failed
- chrome: 3 of 718
- msedge: 3 of 716
- chromium: 1 of 720
Some of those failures are on main itself (e.g. runs 34246196589, 33888071298, 33661279401, 32276523116). The others are on unrelated PRs such as chore(proxy): drop legacy 'per-context' launch proxy handling #42892, feat(video): allow recording video at a custom fps #42752 and fix(webkit): do not report blob: URLs to route handlers #42738. Every failure has the same signature: getByRole('main', { name: 'Dashboard: annotate' }) never becomes visible.

The webkit project on this bot has 0 failures in 727 recorded runs, so there's no history of this exact (project, test) pair failing. That's why this is yellow and not green. I couldn't get this run's artifacts, so I haven't confirmed that the error here matches the Dashboard-not-visible signature. If it does, this is almost certainly the same Windows flake. Re-running the job should clear it.

([microsoft/playwright#42752](https://redirect.github.com/microsoft/playwright/pull/42752), [microsoft/playwright#42758](https://redirect.github.com/microsoft/playwright/pull/42758)) - **🧰 WebMCP tools become real MCP tools** — the tools a page registers through the [WebMCP](https://webmachinelearning.github.io/webmcp/) API now show up right in the tool list as `webmcp_<tool>`, with the page's own input schema and annotations, so an agent can call them directly and let the page do the work instead of driving its UI. The list follows the current tab, and clients get a `tools/list_changed` notification when it changes. This replaces `browser_webmcp_list` / `browser_webmcp_call` from v0.0.81, which are no longer exposed over MCP. Tool names, descriptions, schemas and results come from the page, so treat them as untrusted input. Pass `--no-webmcp` (config `webmcp: false`, env `PLAYWRIGHT_MCP_WEBMCP=false`) to opt out. WebMCP is experimental, see [WebMCP in Chrome](https://developer.chrome.com/docs/ai/webmcp) for how to enable it. ([microsoft/playwright#42671](https://redirect.github.com/microsoft/playwright/pull/42671)) - **🌗 Switch between light and dark color scheme** ([microsoft/playwright#42243](https://redirect.github.com/microsoft/playwright/issues/42243)) — an agent working on a dark theme had no way to see it mid-session. The new **`browser_emulate_media`** tool emulates media features on the fly: `colorScheme`, `reducedMotion`, `forcedColors`, `contrast` and the `media` type (screen / print). Omitted parameters are left unchanged, `null` clears an override. ([microsoft/playwright#42668](https://redirect.github.com/microsoft/playwright/pull/42668)) - **📁 Absolute paths in results** ([microsoft/playwright#42497](https://redirect.github.com/microsoft/playwright/issues/42497)) — links to snapshots, screenshots, console logs and downloads are relative to the workspace root, which a client without one cannot resolve. Pass `--file-paths=absolute` (config `filePaths: "absolute"`, env `PLAYWRIGHT_MCP_FILE_PATHS=absolute`) to get absolute paths instead. ([microsoft/playwright#42673](https://redirect.github.com/microsoft/playwright/pull/42673)) #### 🐛 Fixes - `fix(mcp): keep upload modal and reject bad headers` — a failed `browser_file_upload` (e.g. a missing file) reports the error and keeps the file chooser open so it can be retried, and `browser_route` (opt-in via `--caps=network`) returns an error for a header that is not in the `Name: Value` form instead of setting a header named `""`. ([microsoft/playwright#42713](https://redirect.github.com/microsoft/playwright/pull/42713)) - `fix(chromium): bypass service workers on the storage state page` — `browser_storage_state` (opt-in via `--caps=storage`) no longer runs the site's own scripts, or fails when they redirect, for origins with an active service worker ([microsoft/playwright#42656](https://redirect.github.com/microsoft/playwright/issues/42656)). ([microsoft/playwright#42664](https://redirect.github.com/microsoft/playwright/pull/42664), [microsoft/playwright#42741](https://redirect.github.com/microsoft/playwright/pull/42741)) #### 📦 Upgrading Configs that use `@playwright/mcp@latest` pick this release up on the next client restart. To pin it: ```bash npx @playwright/mcp@0.0.82 ``` ### [`v0.0.81`](https://redirect.github.com/microsoft/playwright-mcp/releases/tag/v0.0.81) [Compare Source](https://redirect.github.com/microsoft/playwright-mcp/compare/v0.0.80...v0.0.81) #### 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](https://redirect.github.com/microsoft/playwright/pull/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](https://redirect.github.com/microsoft/playwright/pull/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](https://redirect.github.com/microsoft/playwright/pull/42663), [#42676](https://redirect.github.com/microsoft/playwright/pull/42676)) - `--image-responses` accepts `only`: a response that carries an image consists of the image parts alone, without the text part ([#42672](https://redirect.github.com/microsoft/playwright/pull/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](https://redirect.github.com/microsoft/playwright/pull/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](https://redirect.github.com/microsoft/playwright/pull/42622), [#42627](https://redirect.github.com/microsoft/playwright/pull/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](https://redirect.github.com/microsoft/playwright/pull/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](https://redirect.github.com/microsoft/playwright/pull/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](https://redirect.github.com/microsoft/playwright/pull/42525)) - Disable the Chromium sandbox by default on Linux for the bundled Chromium build, which lacks the setuid sandbox helper ([#42490](https://redirect.github.com/microsoft/playwright/pull/42490)) </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
