MCP2Browser

A Model Context Protocol (MCP) server that provides browser automation capabilities through HTTP. This server exposes browser inspection tools via the MCP protocol, allowing AI assistants to interact with web pages.

Features

• Open Web Pages: Navigate to any URL using Playwright
• Get Page Title: Retrieve the title of the currently opened page
• HTTP-based MCP server running on Express

Prerequisites

• Node.js (v16 or higher)
• npm or yarn

Installation

1. Clone the repository:

git clone <repository-url>
cd mcp2browser

2. Install dependencies:

npm install

3. Build the project:

npm run build

4. Start the server:

npm start

The server will start running on http://localhost:3000/mcp

Using with VS Code

To use this MCP server with GitHub Copilot in VS Code, you need to configure it in your MCP settings.

Configuration Steps

Option 1: Using MCP: Add Server Command

1. Press Cmd+Shift+P (macOS) or Ctrl+Shift+P (Windows/Linux) to open the command palette
2. Type and select "MCP: Add Server"
3. Enter the server name: browser-mcp
4. Select transport type: HTTP (streamable-http)
5. Enter the server URL: http://localhost:3000/mcp

Option 2: Manual Configuration

1. Open VS Code Settings (JSON) by pressing Cmd+Shift+P (macOS) or Ctrl+Shift+P (Windows/Linux) and searching for "Preferences: Open User Settings (JSON)"

2. Add the MCP server configuration to your settings:

{
  "github.copilot.chat.mcp.servers": {
    "browser-mcp": {
      "type": "http",
      "url": "http://localhost:3000/mcp",
      "transport": "streamable-http"
    }
  }
}

3. Make sure the MCP server is running (see Installation steps above)

4. Restart VS Code or reload the window (Cmd+R on macOS, Ctrl+R on Windows/Linux)

Example Usage

Once configured, you can interact with the browser tools through GitHub Copilot Chat in VS Code:

Example 1: Opening a web page

User: Open the page https://github.com
Copilot: [Uses the openPage tool to navigate to GitHub]

Example 2: Getting the page title

User: What's the title of the current page?
Copilot: [Uses the getPageTitle tool to retrieve the title]

Example 3: Combined workflow
