Why we included this project

Anyone building Next.js apps with an AI coding agent will find this MCP server useful: it connects Claude, Cursor, and similar agents to a running Next.js 16+ dev server and proxies the server's built-in MCP endpoint, so the agent can read live errors, routes, and logs instead of working from stale training data. The server stays deliberately thin. Rather than doing the work itself, it points agents at two tools they run directly: the version-accurate docs that ship inside node_modules and the agent-browser CLI for browser automation. Setup is one npx command in most MCP clients, and once your dev server is running there is no configuration to manage. If you want your coding agent to reason about the actual state of a Next.js app, this is a quick way to get there.
