Playwright MCP MCP Server | MCP Server List

Browser automation using Playwright, enabling LLMs to interact with web pages through structured accessibility snapshots.

A Model Context Protocol (MCP) server that provides browser automation capabilities usingPlaywright. This server enables LLMs to interact with web pages through structured accessibility snapshots, bypassing the need for screenshots or visually-tuned models.

- 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.

- Web navigation and form-filling
- Data extraction from structured content
- Automated testing driven by LLMs
- General-purpose browser interaction for agents

You can install the Playwright MCP server using the VS Code CLI:

# For VS Code code --add-mcp '{"name":"playwright","command":"npx","args":["@hyhfish/mcp-hyh@latest"]}'

After installation, the Playwright MCP server will be available for use with your GitHub Copilot agent in VS Code.

The Playwright MCP server supports the following command-line options:

- --browser <browser>: Browser or chrome channel to use. Possible values:

- chrome,firefox,webkit,msedge
- Chrome channels:chrome-beta,chrome-canary,chrome-dev
- Edge channels:msedge-beta,msedge-canary,msedge-dev
- Default:chrome

Playwright MCP will launch the browser with the new profile, located at

- %USERPROFILE%\AppData\Local\ms-playwright\mcp-{channel}-profile on Windows - ~/Library/Caches/ms-playwright/mcp-{channel}-profile on macOS - ~/.cache/ms-playwright/mcp-{channel}-profile on Linux

All the logged in information will be stored in that profile, you can delete it between sessions if you'd like to clear the offline state.

The Playwright MCP server can be configured using a JSON configuration file. Here's the complete configuration format:

{ // Browser configuration browser?: { // Browser type to use (chromium, firefox, or webkit) browserName?: 'chromium' | 'firefox' | 'webkit'; // Path to user data directory for browser profile persistence userDataDir?: string; // Browser launch options (see Playwright docs) // @see https://playwright.dev/docs/api/class-browsertype#browser-type-launch launchOptions?: { channel?: string; // Browser channel (e.g. 'chrome') headless?: boolean; // Run in headless mode executablePath?: string; // Path to browser executable // ... other Playwright launch options }; // Browser context options // @see https://playwright.dev/docs/api/class-browser#browser-new-context contextOptions?: { viewport?: { width: number, height: number }; // ... other Playwright context options }; // CDP endpoint for connecting to existing browser cdpEndpoint?: string; // Remote Playwright server endpoint remoteEndpoint?: string; }, // Server configuration server?: { port?: number; // Port to listen on host?: string; // Host to bind to (default: localhost) }, // List of enabled capabilities capabilities?: Array< 'core' | // Core browser automation 'tabs' | // Tab management 'pdf' | // PDF generation 'history' | // Browser history 'wait' | // Wait utilities 'files' | // File handling 'install' | // Browser installation 'testing' // Testing >; // Enable vision mode (screenshots instead of accessibility snapshots) vision?: boolean; // Directory for output files outputDir?: string; // Network configuration network?: { // List of origins to allow the browser to request. Default is to allow all. Origins matching both allowedOrigins and blockedOrigins will be blocked. allowedOrigins?: string[]; // List of origins to block the browser to request. Origins matching both allowedOrigins and blockedOrigins will be blocked. blockedOrigins?: string[]; }; /  Do not send image responses to the client. / noImageResponses?: boolean; }

You can specify the configuration file using the--configcommand line option:

npx @hyhfish/mcp-hyh@latest --config path/to/config.json

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--portflag to enable SSE transport.

And then in MCP client config, set theurlto the SSE endpoint:

{ "mcpServers": { "playwright": { "url": "http://localhost:8931/sse" } } }

NOTE:The Docker implementation only supports headless chromium at the moment.

{ "mcpServers": { "playwright": { "command": "docker", "args": ["run", "-i", "--rm", "--init", "--pull=always", "mcr.microsoft.com/playwright/mcp"] } } }

You can build the Docker image yourself.

docker build -t mcr.microsoft.com/playwright/mcp .

import http from 'http'; import { createServer } from '@hyhfish/mcp-hyh'; import { SSEServerTransport } from '@modelcontextprotocol/sdk/server/sse.js'; http.createServer(async (req, res) => { // ... // Creates a headless Playwright MCP server with SSE transport const connection = await createConnection({ browser: { launchOptions: { headless: true } } }); const transport = new SSEServerTransport('/messages', res); await connection.connect(transport); // ... });

- Snapshot Mode(default): Uses accessibility snapshots for better performance and reliability
- Vision Mode: Uses screenshots for visual-based interactions

To use Vision Mode, add the--visionflag when starting the server:

{ "mcpServers": { "playwright": { "command": "npx", "args": [ "@hyhfish/mcp-hyh@latest", "--vision" ] } } }

Vision Mode works best with the computer use models that are able to interact with elements using X Y coordinate space, based on the provided screenshot.
