ThinkBrowse — AI Frontend Testing for Claude Code & Cursor

Stop the manual screenshot loop. ThinkBrowse gives your AI coding agent direct access to your real Chrome browser — with your cookies, your sessions, your extensions. Navigate, click, screenshot, and QA without switching tabs.

Works with Claude Code, Cursor, Cline, Windsurf, and any MCP client.

Install

npx @thinkbrowse/mcp

Or install the CLI globally:

npm install -g @thinkbrowse/cli

The CLI automatically installs the native host binary, which lets AI tools control Chrome.

Add to your MCP config

{
  "mcpServers": {
    "thinkbrowse": {
      "command": "npx",
      "args": ["@thinkbrowse/mcp"]
    }
  }
}

Config location:

• Claude Code: ~/.claude/settings.json
• Cursor: .cursor/mcp.json
• Cline: VS Code settings → Cline MCP Servers

Then ask your agent: "navigate to localhost:3000 and screenshot the checkout page"
