README

Integrated Browser MCP

[![Release](https://img.shields.io/github/v/release/thimo/vscode-integrated-browser-mcp?label=release)](https://github.com/thimo/vscode-integrated-browser-mcp/releases) [![VS Code Marketplace](https://img.shields.io/badge/marketplace-install-blue)](https://marketplace.visualstudio.com/items?itemName=thimo.integrated-browser-mcp)

Exposes VS Code's integrated browser to external agents (Claude Code, scripts, curl) via a local HTTP API and MCP server.

Every existing browser automation solution targets an external Chrome process. This extension is different: it bridges the browser **already inside VS Code** — with your session cookies, your localhost dev server, your DevTools — to any agent that can speak HTTP or MCP.

How it works

Claude Code / curl / scripts
    │
    │  MCP (stdio) or HTTP
    ▼
MCP Server  ──HTTP──▶  VS Code Extension  ──CDP──▶  Integrated Browser
                       localhost:3788+               (real Chromium, in-editor)

The extension uses VS Code's built-in `editor-browser` and the Chrome DevTools Protocol (CDP) to provide full browser automation: navigation, JavaScript evaluation, clicking, typing, screenshots, DOM access, console and network monitoring.

Getting started

Install from the VS Code Marketplace, or run:

code --install-extension thimo.integrated-browser-mcp

The bridge starts automatically. Agents reach it over a unix socket (named pipe on Windows) at ~/.integrated-browser-mcp/sockets/ — set integratedBrowserMcp.transport to tcp for the classic localhost:3788 port instead
For Claude Code: the MCP server is auto-configured in ~/.claude.json on first activation
The browser launches lazily on the first request — no browser tab until you need one
