 A Model Context Protocol (MCP) server that provides browser automation capabilities using [Playwright](https://playwright.dev). 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](https://github.com/microsoft/playwright-cli) 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.<br>**Learn more about [Playwright CLI with SKILLS](https://github.com/microsoft/playwright-cli)**.
+
+- **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.

+The Playwright MCP Chrome Extension allows you to connect to existing browser tabs and leverage your logged-in sessions and browser state. See [packages/extension/README.md](packages/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-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.
+
+```ts
+// 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.
+This is useful for overriding browser APIs or setting up the environment.
+
+```js
+// init-script.js
+window.isPlaywrightMCP = true;
+```
