📇 🏠 - An MCP server paired with a browser extension that enables LLM clients to control the user's browser (Firefox).
Install
npx -y browser-control-mcpRequired environment variables
EXTENSION_SECRETSet in your MCP configclaude_desktop_config.json
{
"mcpServers": {
"eyalzh-browser-control-mcp": {
"command": "npx",
"args": [
"-y",
"browser-control-mcp"
],
"env": {
"EXTENSION_SECRET": "<YOUR_EXTENSION_SECRET>"
}
}
}
}Add this to your Claude Desktop config file. Find it at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS.
What this does
eyalzh/browser-control-mcp exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation. That makes it useful when you want Claude to reach into live web pages and browser sessions without copy-pasting context every turn.
Requirements
This server needs the following environment variables to be set before it can run:
EXTENSION_SECRET
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
Common use cases
- •Navigate, fill forms, and scrape pages on demand from Claude
- •Test UI flows or capture screenshots as part of a debugging session
- •Reach data behind logins or interactive pages that simple HTTP fetch cannot
