devtools-debugger-mcp

Was er kann

A local MCP server that lets an assistant debug Node.js programs through the Chrome DevTools Protocol. It launches a script under Node's inspector, paused on the first line, and then lets the agent set breakpoints by file and line or by URL pattern, including conditional breakpoints and logpoints, choose when to pause on exceptions, step over, into and out, inspect local and closure scopes, evaluate expressions in the current frame and read console output captured since the last step. Source maps let it debug TypeScript and other compiled code. It is installed from npm and added to the client's MCP settings as a node command.
