playwright-mcp

MCP server for browser automation via Playwright.

Source: @playwright/mcp

Environment Variables

Variable Required Description
PLAYWRIGHT_MCP_HEADLESS No Run headless (true/false, default: true)
PLAYWRIGHT_MCP_BROWSER No Browser to use (firefox, chromium, webkit, default: chromium)

Usage

This MCP runs better natively (not in a container) because it needs direct display access for headed mode and browser binaries.

# or with options:
PLAYWRIGHT_MCP_HEADLESS=true PLAYWRIGHT_MCP_BROWSER=firefox npx @playwright/mcp

For headed mode (visible browser window), ensure a display is available and run:

PLAYWRIGHT_MCP_HEADLESS=false PLAYWRIGHT_MCP_BROWSER=firefox npx @playwright/mcp
