MCP Browser Extension
Website and docs: mcp-browser-extension.com · Quickstart · All 42 tools · Install the extension from the Chrome Web Store
Let Claude use the Chrome you are already logged into. Not a fresh automated browser that greets every site as a stranger — your Chrome, with your sessions, your cookies, your 2FA already done. If you can see a page in your browser, your agent can read it, without logging in again and without pasting credentials anywhere.
Most browser MCP servers launch their own Chromium and hand your agent a signed-out window. MCP Browser Extension does the opposite: an MV3 extension dials into a localhost WebSocket server and drives the browser you already have open, through chrome.scripting/chrome.tabs. Works with Claude Code, Claude Desktop, and any other MCP host.
MCP Browser Extension has two parts: the extension, and a small MCP server you run with npx (npm package and command: mcp-browser-extension). The extension comes from the Chrome Web Store or loaded unpacked.
This build is extension-only. It never launches or attaches a Chromium of
its own, so the extension is required, not optional — without it, no tool
can run. The CDP flags (--cdp-fallback, --no-cdp-fallback, --cdp-endpoint,
--prefer) are still accepted for back-compat but are ignored.
Full design: docs/BLUEPRINT.md — architecture, wire
protocol, the complete tool surface, the extension manifest, the security
model, and the phased build plan.
Use Claude in your signed-in Chrome
You are already signed in to Gmail, GitHub, your analytics dashboards, the admin panel, the CRM. MCP Browser Extension lets Claude (Claude Code, Claude Desktop, or any other MCP host) work in those same tabs: no re-login, no second 2FA prompt, no password or cookie in a config file. The extension runs inside your normal Chrome, so a page the agent opens is the page you would see.

Other tools drive a signed-in Chrome too (the hangwin/mcp-chrome extension, for one), so the question is what you get on top of the session:
