AI agents check for free ports with PortPeek MCP

AI tools sometimes crash because they try to use network ports already taken by other apps. PortPeek MCP is a tool that lets these AI agents see which ports are free before they start working.

When you develop software with AI assistants, they often need to run a local server to show you their work. However, if another app is already using that specific connection point, the AI will fail or cause an error. This new tool, PortPeek MCP, gives the AI the ability to scan your computer's active connections. By checking the status of these ports first, the AI can choose an available one automatically. This prevents frustrating technical glitches and keeps your workflow smooth without manual troubleshooting.

Key points

  • Finds available network ports for AI agents to use
  • Prevents errors caused by multiple apps trying to use the same connection
  • Helps AI tools like Cursor run local servers more reliably
  • Saves time spent manually checking and closing background apps
