Overview

Provides a Model Context Protocol (MCP) server that acts as a comprehensive development toolkit for Next.js projects, enabling AI agents to interact with live dev servers, access documentation, automate upgrades, set up Cache Components, and perform browser-based testing.

Installation

Run Command
npx -y next-devtools-mcp@latest

Security Notes

The `browser_eval` tool includes an `evaluate` action that allows arbitrary JavaScript code to be executed within a browser context controlled by Playwright. While this is an intended feature for web automation and testing, it presents a security risk if the AI agent invoking this tool is compromised or misinstructed, potentially leading to malicious script execution within the user's browser session. The server itself does not expose direct arbitrary code execution on the host machine via `eval` in its Node.js process. Telemetry data collection is anonymous and opt-out capable.
