GitHub stars
Chrome extension that lets AI assistants control your browser directly - open tabs, take screenshots, extract content, and manage bookmarks using your existing Chrome setup.
Chrome MCP is a community-built MCP server published by hangwin that provides AI assistants with tools and capabilities via the Model Context Protocol. Chrome extension-based MCP server that exposes browser functionality to AI assistants. Control tabs, capture screenshots It is categorized under browser automation, developer tools.
You can install Chrome MCP in your AI client of choice. Use the install panel on this page to get one-click setup for Cursor, Claude Desktop, VS Code, and other MCP-compatible clients. This server runs locally on your machine via the stdio transport.

Chrome MCP is released under the MIT license. This is a permissive open-source license, meaning you can freely use, modify, and distribute the software.
Fetch and extract information from websites automatically
Example
Research competitor pricing, scrape product reviews, monitor news mentions
Automate 5-10 hours/week of manual web research
Track website changes, new content, price updates
Example
Monitor competitor blog for new posts, track stock availability, watch for pricing changes
Stay informed without manual checking, never miss important updates
Extract structured data from multiple websites
Example
Compile product listings from 10 e-commerce sites, aggregate job postings, collect real estate data
Build datasets 100x faster than manual copying
Share your MCP server with the developer community
We evaluated Chrome MCP against two servers with overlapping tools; this profile had the clearer scope statement.
According to our notes, Chrome MCP benefits from clear Model Context Protocol framing — fewer ambiguous “AI plugin” claims.
Chrome MCP has been reliable for tool-calling workflows; the MCP profile page is a good permalink for internal docs.
Useful MCP listing: Chrome MCP is the kind of server we cite when onboarding engineers to host + tool permissions.
Strong directory entry: Chrome MCP surfaces stars and publisher context so we could sanity-check maintenance before adopting.
Chrome MCP reduced integration guesswork — categories and install configs on the listing matched the upstream repo.

I recommend Chrome MCP for teams standardizing on MCP; the explainx.ai page compares cleanly with sibling servers.

🌟 Turn your Chrome browser into your intelligent assistant - Let AI take control of your browser, transforming it into a powerful AI-controlled automation tool.
The project is still in its early stages and is under intensive development. More features, stability improvements, and other enhancements will follow.
Chrome MCP Server is a Chrome extension-based Model Context Protocol (MCP) server that exposes your Chrome browser functionality to AI assistants like Claude, enabling complex browser automation, content analysis, and semantic search. Unlike traditional browser automation tools (like Playwright), Chrome MCP Server directly uses your daily Chrome browser, leveraging existing user habits, configurations, and login states, allowing various large models or chatbots to take control of your browser and truly become your everyday assistant.
| Comparison Dimension | Playwright-based MCP Server | Chrome Extension-based MCP Server |
|---|---|---|
| Resource Usage | ❌ Requires launching independent browser process, installing Playwright dependencies, downloading browser binaries, etc. | ✅ No need to launch independent browser process, directly utilizes user's already open Chrome browser |
| User Session Reuse | ❌ Requires re-login | ✅ Automatically uses existing login state |
| Browser Environment | ❌ Clean environment lacks user settings | ✅ Fully preserves user environment |
| API Access | ⚠️ Limited to Playwright API | ✅ Full access to Chrome native APIs |
| Startup Speed | ❌ Requires launching browser process | ✅ Only needs to activate extension |
| Response Speed | 50-200ms inter-process communication | ✅ Faster |

npm
npm install -g mcp-chrome-bridge
pnpm
# Method 1: Enable scripts globally (recommended)
pnpm config set enable-pre-post-scripts true
pnpm install -g mcp-chrome-bridge
# Method 2: Manual registration (if postinstall doesn't run)
pnpm install -g mcp-chrome-bridge
mcp-chrome-bridge register
Note: pnpm v7+ disables postinstall scripts by default for security. The
enable-pre-post-scriptssetting controls whether pre/post install scripts run. If automatic registration fails, use the manual registration command above.
chrome://extensions/your/dowloaded/extension/folderAdd the following configuration to your MCP client configuration (using CherryStudio as an example):
Streamable HTTP connection method is recommended
{
"mcpServers": {
"chrome-mcp-server": {
"type": "streamableHttp",
"url": "http://127.0.0.1:12306/mcp"
}
}
}
If your client only supports stdio connection method, please use the following approach:
# npm check method
npm list -g mcp-chrome-bridge
# pnpm check method
pnpm list -g mcp-chrome-bridge
Assuming the command above outputs the path: /Users/xxx/Library/pnpm/global/5 Then your final path would be: /Users/xxx/Library/pnpm/global/5/node_modules/mcp-chrome-bridge/dist/mcp/mcp-server-stdio.js
{
"mcpServers": {
"chrome-mcp-stdio": {

]
}

Interact with services that don't offer APIs
Example
Check form submissions, validate website functionality, test user flows
Automate interactions with any website, even without API
Prerequisites
Time Estimate
20-40 minutes including configuration and testing
Steps

✗ Don't
💡 Pro Tips
Architecture
MCP server handles HTTP requests, HTML parsing, JavaScript rendering (if headless browser), and returns structured data to Claude.
Protocols
Compatibility
✓ Use when
Use for research automation, content monitoring, data aggregation from multiple sources, and when official APIs don't exist. Best for read-only information gathering.
✗ Avoid when
Avoid for sites with APIs (use API instead), sites that explicitly forbid scraping, when data is copyrighted, or for login-required content without proper authorization.
