Overview

Expose live browser state (DOM, Network, Console, Styles) as MCP tools for AI agents like Cursor.

BRMS (Browser Runtime MCP Server) brings live browser context into AI-assisted debugging workflows. With BRMS, compatible MCP clients like Cursor can inspect the current browser tab and access structured runtime signals such as DOM tree snapshots, CSS selector matches, computed styles, layout details, visible interactive elements, screenshots, console errors, network activity, and event listeners. This helps developers debug UI issues faster by giving AI tools direct access to the state of the page instead of relying only on pasted code or manual descriptions. BRMS is especially useful for diagnosing problems like hidden or overlapping elements, broken requests, missing resources, layout issues, and runtime errors. Key capabilities include: - List and select open browser tabs - Inspect the DOM and query elements by selector - Read computed styles and layout information - Capture screenshots of the page or specific elements - Review console errors and network calls - Analyze visible interactive elements and event listeners - Correlate browser issues across DOM, network, and console signals - BRMS works through a Chrome Extension plus a local Native Messaging Host, exposing a local MCP endpoint that your AI coding assistant can use during development. It is designed for local, developer-focused workflows and helps make browser debugging more interactive, accurate, and efficient.
