This commit batches the pending workspace updates that were coupled in practice: extension reliability fixes, ghost cursor persistence across MPA navigations, timeout tuning, and aligned docs/versioning updates so behavior and guidance stay in sync. Key updates:\n- extension: add MV3 keepalive via chrome.alarms, add alarms permission, and bump extension changelog/version to 0.0.73 to reduce silent relay disconnects while idle\n- playwriter runtime: raise default action timeout to 60s while keeping navigation timeout separate; increase relay /version fetch timeout to 2000ms\n- recording + cursor: add persistent cursor init scripts with Page.addScriptToEvaluateOnNewDocument, remove init script on teardown, and ensure cursor enablement before applying mouse actions\n- demo video defaults: use 0.5s side buffer (1s total) and default idle speed 6x for createDemoVideo/computeIdleSections\n- tests/docs: keep click-error tests deterministic with explicit 5000ms per-click timeout, remove outdated click-timeout section from skill mistakes, and update package/changelog entries
Playwriter MCP
Control your Chrome browser via Model Context Protocol (MCP) using Chrome DevTools Protocol (CDP) events.
What is Playwriter MCP?
Playwriter MCP is a Chrome extension that enables Playwright to connect to your existing Chrome instance without spawning a new browser or requiring Chrome to be started in CDP mode. This allows AI assistants and automation tools to interact with your browser seamlessly through the Model Context Protocol.
Key Features
- No new Chrome instances: Works with your current browser session
- No CDP mode required: No need to restart Chrome with special flags
- MCP integration: Exposes browser control through the Model Context Protocol
- CDP events: Full access to Chrome DevTools Protocol capabilities
- Playwright compatible: Connect Playwright directly to your running Chrome
How it Works
- Install the extension in your Chrome browser
- Click the extension icon to attach the debugger to the current tab
- The extension creates a relay connection using CDP
- Connect your MCP client (like Playwright) to control the browser
- The icon changes color to indicate connection status:
- Gray: Not connected
- Green: Successfully connected
Use Cases
- Browser automation without disrupting your workflow
- AI-assisted web browsing and testing
- Debugging and development with MCP-enabled tools
- Remote browser control for various applications
Permissions
This extension requires the following permissions:
- debugger: To access Chrome DevTools Protocol
- activeTab: To interact with the current tab
- tabs: To manage browser tabs
- all_urls: To work with any website
Getting Started
- Install the extension from the Chrome Web Store
- Navigate to any webpage
- Click the Playwriter MCP extension icon
- The debugger will attach and the icon will turn green when connected
- Connect your MCP client to start controlling the browser
Privacy & Security
Playwriter MCP runs locally in your browser and does not send any data to external servers. All browser control happens through the standard Chrome DevTools Protocol on your machine.
