MCP Browser Kit M2 por mcp-browser-kit

MCP Browser Kit is a high-performance browser extension and Model Context Protocol (MCP) server bridge designed to empower AI assistants, coding agents, and LLMs to seamlessly interact with your local web browser.

Built on open standards, MCP Browser Kit bridges the gap between your local AI development environment (such as Claude Desktop, Antigravity, or custom MCP clients) and your live Firefox browser sessions.

• Readable Page Extraction: Converts raw HTML DOM into structured, clean readable text suited for LLM context windows.
• Interactive Element Inspection: Automatically indexes buttons, form inputs, links, and clickable controls with unique selectors.
• Tab & Window Context Awareness: Allows AI agents to list active tabs, inspect tab titles/URLs, and switch between browser contexts dynamically.

• Element Interaction: Supports element clicking, coordinate targeting, scrolling, and keyboard input.
• Smart Form Auto-Fill: Intelligently fills textboxes, textareas, checkboxes, dropdowns, and rich content-editable fields.
• JavaScript Execution: Safely invokes custom script routines in page contexts for advanced browser workflows.
• Media & Visual Snapshots: Enables agents to capture visual tab snapshots for multimodal reasoning.

Security and user privacy are foundational principles of MCP Browser Kit:
- 100% Local Communication: All communication takes place strictly over your local loopback interface (127.0.0.1).
- No Third-Party Analytics: No telemetry, browsing history, or personal data is ever collected or dispatched to remote cloud servers.
- User-In-The-Loop Control: Browser actions are triggered only when explicitly requested by your local AI assistant during active sessions.

1. Install the Extension: Keep this Firefox extension enabled in your browser.
2. Start the MCP Server: Run the lightweight companion server in your terminal:
   bash
npx @mcp-browser-kit/server@latest
3. Configure Your AI Assistant: Add the MCP server entry to your client configuration (e.g. mcpServers in Claude Desktop or Antigravity):
   json
{
"mcpServers": {
"browser-kit": {
"command": "npx",
"args": ["@mcp-browser-kit/server@latest"]
}
}
}
4. Start Automating: Ask your AI assistant to read pages, automate tasks, or fill forms directly in Firefox!
