chrome-devtools-mcp

chrome-devtools-mcp is an official MCP server that hands coding agents the full Chrome DevTools protocol — inspect the DOM, read console errors, trace network requests, and drive the page like a real browser session.

It turns "the button doesn’t work" into something your agent can actually debug, live, instead of guessing from source. If you build web apps with an agent in the loop, this is one of the highest-leverage MCP servers to add.
