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.

Playwright MCP vs Playwright CLI

This package provides MCP interface into Playwright. If you are using a coding agent, you might benefit from using the CLI+SKILLS instead.

CLI: Modern coding agents increasingly favor CLI–based workflows exposed as SKILLs over MCP because CLI invocations are more token-efficient: they avoid loading large tool schemas and verbose accessibility trees into the model context, allowing agents to act through concise, purpose-built commands. This makes CLI + SKILLs better suited for high-throughput coding agents that must balance browser automation with large codebases, tests, and reasoning within limited context windows.
Learn more about Playwright CLI with SKILLS.
MCP: MCP remains relevant for specialized agentic loops that benefit from persistent state, rich introspection, and iterative reasoning over page structure, such as exploratory automation, self-healing tests, or long-running autonomous workflows where maintaining continuous browser context outweighs token cost concerns.

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.

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.

# Windows
%USERPROFILE%\AppData\Local\ms-playwright\mcp-{channel}-{workspace-hash}

# macOS
- ~/Library/Caches/ms-playwright/mcp-{channel}-{workspace-hash}

# Linux
- ~/.cache/ms-playwright/mcp-{channel}-{workspace-hash}

{workspace-hash} is derived from the MCP client's workspace root, so different projects get separate profiles automatically.

Important

A persistent profile can only be used by one browser instance at a time, so concurrent MCP clients sharing the same workspace will conflict. To run several clients in parallel, start each additional client with --isolated or point it at a distinct --user-data-dir.

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.

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": [
        "@playwright/mcp@latest",
        "--isolated",
        "--storage-state={path/to/storage.json}"
      ]
    }
  }
}

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 microsoft/playwright › packages/extension 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-dir argument. This will persist all browser data between the sessions.
Start with a storage state file using the --storage-state argument. This will load cookies and local storage from the file into an isolated browser context.

For the page state, you can use:

--init-page to 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-page.ts
export default async ({ page }) => {
  await page.context().grantPermissions(['geolocation']);
  await page.context().setGeolocation({ latitude: 37.7749, longitude: -122.4194 });
  await page.setViewportSize({ width: 1280, height: 720 });
};

--init-script to 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. Thi
