What is the Dev MCP Server?

MCP Dev Server Manager - A daemon for managing development servers

What it actually does

A daemon that accepts requests from MCP clients to start dev servers, allocating unique ports to avoid collisions and shutting down idle connections after 120s of inactivity.

  • Run multiple dev servers in parallel — useful if you want to use automated testing tools eg Playwright or Google Dev Tools MCP
  • Avoid port collisions — when working with websites, it's often necessary to specify different ports if you want to run multiple dev servers
  • Automatic port allocation — starting at 3010 with reuse
  • Log capture — with 512KB ring buffers per server
  • Auto-cleanup — of idle sessions after 120 seconds (configurable via --idle-timeout)
