Give your AI agents, QA scripts, and integrations a real browser — with a REST API, built-in MCP server, and network interception out of the box.
# Create a tab and navigate curl -X POST http://localhost:3000/api/browser/tabs \ -H "Content-Type: application/json" \ -d '{"url": "https://example.com"}' # Click a button on the page curl -X POST http://localhost:3000/api/browser/tabs/0/click \ -d '{"selector": "button.submit"}' # Get the page content curl http://localhost:3000/api/browser/tabs/0/source?type=text
Point Claude Desktop or any MCP-compatible agent at LumaBrowser's built-in MCP server. Navigate, click, and evaluate the DOM natively — no glue code required.
SPAs and randomized CSS classes break scripts daily. LumaBrowser's REST API with on-board LLM Template Builder resolves selectors dynamically, keeping your scripts stable.
Use the CDP-based Network Watcher to intercept HTTP traffic without root certificates or proxy setups, and forward it directly to your backend.
Three lines to navigate, click, and extract — against any website.
