Playwright Tools for MCP
概覽
以 Playwright 為基礎的瀏覽器自動化伺服器,讓助理不需視覺模型就能瀏覽網頁、讀取無障礙快照,並點擊、輸入或填寫表單。
- 可以做什麼
- 瀏覽頁面、返回上一頁、調整視窗大小並關閉瀏覽器
- 透過無障礙快照、截圖、主控台訊息與網路請求檢視頁面
- 操作元素:點擊、懸停、拖放、輸入文字、按鍵、選擇下拉選項與填寫表單
- 在頁面上執行 JavaScript 或 Playwright 程式碼片段、上傳檔案並處理對話框
- 等待條件成立,並在啟用相關能力時產生 PDF 或視覺化輸出
- 適用情境
- 適合需要助理操作真實瀏覽器的情境:測試網頁應用程式、填寫並送出表單、查看主控台或網路輸出,或以結構化無障礙資料而非截圖方式擷取頁面內容。
- 執行需求
- 以 npm 套件或 Docker 映像透過 stdio 在本機執行;需要 Node.js 18 或更新版本,以及 VS Code、Cursor、Claude Desktop、Goose 等 MCP 用戶端。另需可用的瀏覽器(Chromium、Firefox、WebKit 或 Edge)。清單宣告了一個名為 YOUR_API_KEY 的必填密鑰,但 README 未說明其用途。
安裝
在 SourceWeft 中
- 開啟 儀表板中的 Playwright Mcp,將其新增到工作區。
- 為需要使用其工具的對話啟用該服務。
Desktop only,透過 STDIO。 STDIO 服務會啟動本機處理程序,因此需要 SourceWeft 桌面主機。
其他 MCP 客戶端

Playwright MCP
A Model Context Protocol (MCP) server that provides browser automation capabilities using Playwright. This server enables LLMs to interact with web pages through structured accessibility snapshots, bypassing the need for screenshots or visually-tuned models.
Key Features
- Fast and lightweight. Uses Playwright's accessibility tree, not pixel-based input.
- LLM-friendly. No vision models needed, operates purely on structured data.
- Deterministic tool application. Avoids ambiguity common with screenshot-based approaches.
Requirements
- Node.js 18 or newer
- VS Code, Cursor, Windsurf, Claude Desktop, Goose or any other MCP client
Getting started
First, install the Playwright MCP server with your client.
Standard config works in most of the tools:
[Install in VS Code] [Install in VS Code Insiders]
Amp
Add via the Amp VS Code extension settings screen or by updating your settings.json file:
Amp CLI Setup:
Add via the amp mcp addcommand below
Claude Code
Use the Claude Code CLI to add the Playwright MCP server:
Claude Desktop
Follow the MCP install guide, use the standard config above.
Codex
Use the Codex CLI to add the Playwright MCP server:
Alternatively, create or edit the configuration file ~/.codex/config.toml and add:
For more information, see the Codex MCP documentation.
Cursor
Click the button to install:
Or install manually:
Go to Cursor Settings -> MCP -> Add new MCP Server. Name to your liking, use command type with the command npx @playwright/mcp@latest. You can also verify config or add command like arguments via clicking Edit.
Factory
Use the Factory CLI to add the Playwright MCP server:
Alternatively, type /mcp within Factory droid to open an interactive UI for managing MCP servers.
For more information, see the Factory MCP documentation.
Gemini CLI
Follow the MCP install guide, use the standard config above.
Goose
Click the button to install:
Or install manually:
Go to Advanced settings -> Extensions -> Add custom extension. Name to your liking, use type STDIO, and set the command to npx @playwright/mcp. Click "Add Extension".
Kiro
Follow the MCP Servers documentation. For example in .kiro/settings/mcp.json:
LM Studio
Click the button to install:
[Add MCP Server playwright to LM Studio]
Or install manually:
Go to Program in the right sidebar -> Install -> Edit mcp.json. Use the standard config above.
opencode
Follow the MCP Servers documentation. For example in ~/.config/opencode/opencode.json:
Qodo Gen
Open Qodo Gen chat panel in VSCode or IntelliJ → Connect more tools → + Add new MCP → Paste the standard config above.
Click Save.
VS Code
Click the button to install:
[Install in VS Code] [Install in VS Code Insiders]
Or install manually:
Follow the MCP install guide, use the standard config above. You can also install the Playwright MCP server using the VS Code CLI:
After installation, the Playwright MCP server will be available for use with your GitHub Copilot agent in VS Code.
Warp
Go to Settings -> AI -> Manage MCP Servers -> + Add to add an MCP Server. Use the standard config above.
Alternatively, use the slash command /add-mcp in the Warp prompt and paste the standard config from above:
Windsurf
Follow Windsurf MCP documentation. Use the standard config above.
Configuration
Playwright MCP server supports following arguments. They can be provided in the JSON configuration above, as a part of the "args" list:
User profile
You can run Playwright MCP with persistent profile like a regular browser (default), in isolated contexts for testing sessions, or connect to your existing browser using the browser extension.
Persistent profile
All the logged in information will be stored in the persistent profile, you can delete it between sessions if you'd like to clear the offline state.
Persistent profile is located at the following locations and you can override it with the --user-data-dir argument.
Isolated
In the isolated mode, each session is started in the isolated profile. Every time you ask MCP to close the browser,
the session is closed and all the storage state for this session is lost. You can provide initial storage state
to the browser via the config's contextOptions or via the --storage-state argument. Learn more about the storage
state here.
Browser Extension
The Playwright MCP Chrome Extension allows you to connect to existing browser tabs and leverage your logged-in sessions and browser state. See extension/README.md for installation and setup instructions.
Initial state
There are multiple ways to provide the initial state to the browser context or a page.
For the storage state, you can either:
- Start with a user data directory using the
--user-data-dirargument. This will persist all browser data between the sessions. - Start with a storage state file using the
--storage-stateargument. This will load cookies and local storage from the file into an isolated browser context.
For the page state, you can use:
--init-pageto point to a TypeScript file that will be evaluated on the Playwright page object. This allows you to run arbitrary code to set up the page.
--init-scriptto point to a JavaScript file that will be added as an initialization script. The script will be evaluated in every page before any of the page's scripts. This is useful for overriding browser APIs or setting up the environment.
Configuration file
The Playwright MCP server can be configured using a JSON configuration file. You can specify the configuration file
using the --config command line option:
Configuration file schema
Standalone MCP server
When running headed browser on system w/o display or from worker processes of the IDEs,
run the MCP server from environment with the DISPLAY and pass the --port flag to enable HTTP transport.
And then in MCP client config, set the url to the HTTP endpoint:
Docker
NOTE: The Docker implementation only supports headless chromium at the moment.
Or If you prefer to run the container as a long-lived service instead of letting the MCP client spawn it, use:
The server will listen on host port 8931 and can be reached by any MCP client.
You can build the Docker image yourself.
