If we consider all human operations on a computer as the universal set, then the operational scope of Computer, Browser, CDP, and puppeteer can be categorized as follows:

• Computer: The universal set of all operations
• Browser: App-level permissions. Browser restricts many capabilities for security, such as direct access to local files
• CDP: Focused on debugging capabilities. Non-debugging information of the browser (such as bookmarked web pages) cannot be accessed
• puppeteer: Built on top of CDP, but doesn't utilize all CDP APIs, so its capabilities are a subset of CDP

In Browser-Use scenarios, unlike VNC which is a more general screen casting solution, CDP has capability boundaries. Therefore, understanding its strengths and limitations is significant for overall architectural design and future evolution direction.

Chrome DevTools Protocol (CDP) is the core communication protocol for Chromium browser debugging tools: it's based on JSON format and enables bidirectional real-time interaction between clients and the browser kernel through WebSocket.

On September 23, 2025, Google released Chrome DevTools MCP, currently at version 0.9.0. Google positions it as an assistant for AI coding agents to handle debugging and performance testing, improving web development debug capabilities. See the official blog for use cases: Chrome DevTools (MCP) for your AI agent.

This post analyzes Chrome DevTools MCP's implementation by examining the source code and MCP output, exploring its capabilities and limitations.
