Chrome DevTools MCP v0.21.0: Multi-Agent PageId Routing Enables Parallel Browser Automation
Google shipped Chrome DevTools MCP v0.21.0 with a critical new capability: pageId routing lets multiple AI agents precisely target and interact with specific browser pages in parallel, solving the fundamental problem of multi-agent browser coordination. The update also adds new auditing capabilities. With 1,542 likes and 115K views on the announcement tweet, the developer community sees this as removing the last major blocker for AI agents that can actually see and debug their own output in real browsers.
