Overview
Browser MCP runs an MCP server (npx @browsermcp/mcp@latest) that forwards a `browser` tool to a per-user local daemon. The daemon controls Chrome tabs with Playwright through a chrome.debugger extension that only talks to 127.0.0.1. It works with Claude Code, Cursor, VS Code, Codex and Claude Desktop, using your existing profile and logged-in sites.
Who it is for: Developers giving MCP-capable coding agents control of their own Chrome
Strengths
- Uses your real Chrome profile and signed-in sessions instead of a fresh headless browser
- Everything runs locally; extension connects only to the daemon on 127.0.0.1
- Pairing requires clicking Allow and matching a six-digit code once per computer
- Extension refuses incognito, browser pages and extension pages unless configured, and has a Stop button
Weaknesses
- Chromium browsers only; Firefox has no debugger API so it does not work
- Self-built extension must be updated by hand with git pull and rebuild
- Needs Node.js 24 or later to build; having both store and self-built extensions causes double connections
- No release published; version tracking relies on the npm package
What it needs
- no GPU
- Needs Node.js 24+, Chrome or Chromium browser, Browser MCP extension, Playwright
