Browser Gateway
Give Claude Code or Cursor real Chrome CDP control—navigate, screenshot, and click—without wiring brittle one-off scripts.
Overview
Browser Gateway is a Build-phase MCP server that gives coding agents Chrome CDP tools to navigate pages, take screenshots, and interact with the UI with multi-provider failover.
What is this MCP server?
- Chrome DevTools Protocol (CDP) navigation, screenshots, and UI interaction from the agent
- Multi-provider failover when a remote browser backend drops
- stdio npm package browser-gateway (v0.1.8) for Claude Desktop / MCP clients
- Optional BG_TOKEN for authenticated remote gateway providers only
- npm package browser-gateway v0.1.8
- stdio transport
- optional secret env BG_TOKEN

What problem does it solve?
Agents cannot reliably drive a real browser for login flows, visual checks, or multi-step UI tasks without a dedicated MCP bridge.
Who is it for?
Indie builders automating staging checks, competitor page capture, or agent-led UI flows on Chrome CDP.
Skip if: Teams that only need static HTML fetch or who want a fully managed cloud browser with zero local Chrome setup.
What do I get? / Deliverables
After you add the stdio server, your agent can run repeatable CDP browser sessions with optional remote auth and provider failover.
- Registered stdio MCP server exposing navigate/screenshot/interact tools
- Agent-callable browser sessions with optional failover across providers
Recommended MCP Servers
Journey fit
Browser control is wired while you are building agent workflows and integrations, not as a one-time launch task. agent-tooling is the shelf for MCP servers that extend what your coding agent can do in a live browser session.
How it compares
CDP browser MCP integration, not a headless scraping CLI or a single-purpose agent skill.
Common Questions / FAQ
Who is Browser Gateway for?
Solo builders and small teams using Claude Code, Cursor, or other MCP clients who need agent-driven Chrome navigation and interaction.
When should I use Browser Gateway?
Use it during Build when you are wiring agent-tooling for live browser QA, screenshots, or multi-step web UI automation over CDP.
How do I add Browser Gateway to my agent?
Install the npm package browser-gateway, configure stdio in your MCP client, and set BG_TOKEN only if your remote provider requires gateway authentication.
