Browser Mcp Cdp
Drives your local Chrome via CDP with a clever profile snapshot system: it copies your real Chrome cookies and login state to a temp directory, so agents can navigate Gmail or internal dashboards without touching your actual profile. Ships a shared broker process that multiple MCP clients connect to over a Unix socket, avoiding the overhead of launching Chrome per session. Exposes navigate, evaluate, screenshot, click, fill, and tab management tools. The tradeoff is clear: you get access to your logged-in sessions without credential uploads, but you're letting the LLM execute JavaScript in a browser that sees your session tokens. Broker idles out after 10 minutes and cleans up the temp profile.

browser-mcp-cdp
A Model Context Protocol (MCP) server that drives your real local Chrome via the Chrome DevTools Protocol. Designed for agents that need access to your logged-in sessions (Gmail, internal dashboards, banking, etc.) without uploading credentials to a cloud service.
Why another browser MCP?
Different tradeoffs from the alternatives:
| browser-mcp-cdp | Playwright MCP | Chrome DevTools MCP | |
|---|---|---|---|
| Browser | Your local Chrome | Managed Playwright Chromium | Your local Chrome |
| Login state | ✅ Snapshot of your profile (cookies, logins, IndexedDB) | ❌ Fresh profile | ✅ Real profile (modifies it) |
| Profile isolation | ✅ Copy-on-start, real profile untouched | N/A | ⚠️ Direct attach |
| Multi-client | ✅ Shared broker across MCP clients | ❌ Per-client | ❌ Per-client |
| Dependencies | Node only (no Playwright download) | Playwright + browsers | Node only |
The profile snapshot pattern means you can ask an agent to "check my email" — it sees your Gmail logged in — but the agent's actions never modify your real Chrome profile. Each session gets a disposable copy.
