BrowserBridge MCP (Lite Edition)

Free: Genesis Starter Kit (25 .cursorrules/CLAUDE.md rulesets + MCP configs). Try the live config builder. Full stack: all six servers in Genesis Enterprise Suite ($19).

BrowserBridge MCP is a lightweight headless browser session bridge and Accessibility Object Model (AOM) inspector designed for AI coding assistants (Claude Desktop, Cursor, OpenAI Codex, LangGraph).

It enables agents to navigate web applications, extract semantic clean text, and interact with web pages without drowning the LLM context window in massive HTML blobs.

Run without cloning

uvx --from git+https://github.com/johannschiffer/browserbridge-mcp browserbridge-mcp

Claude Desktop / Cursor config entry:

{
  "mcpServers": {
    "browserbridge-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/johannschiffer/browserbridge-mcp",
        "browserbridge-mcp"
      ]
    }
  }
}

🎯 The Problem

When autonomous AI agents interact with web pages:

1. Context Window Exhaustion: Dumping 2MB of raw HTML, scripts, CSS, and SVG icons into an LLM exhausts the token budget within 3 turns.
2. Brittle Selectors: Agents fail to find buttons when modern websites use dynamic, hashed class names (class="btn_3x9a_primary").
3. Zombie Memory Leaks: Unmanaged headless browsers leak memory on the host system when agents drop sessions without cleanup.

BrowserBridge solves this by converting web pages into a compact, token-efficient Accessibility Object Model (AOM) tree (~95% token reduction) and providing clean interaction primitives.

• 🧹 Clean Text Extractor: Strips scripts, ads, and formatting for fast summarization.
• ⚡ Zero Browser Overhead: Pure Python runtime compatible with Claude Desktop and Cursor.
