PortMarshal: Protecting Dev Servers from AI Agent Conflicts

💻 PortMarshal protects local servers from AI agent conflicts

PortMarshal has been released—a tool for macOS and Linux that helps manage local development servers when using multiple AI agents (such as Claude Code or Cursor). The utility allows binding TCP ports to specific projects, preventing the accidental shutdown of other services.

🌍 As the number of autonomous AI agents grows, conflicts over local machine resources arise. Port management is becoming a necessary infrastructure layer.

👤 If you are using multiple AI assistants simultaneously, PortMarshal will help avoid situations where one agent accidentally "kills" another's server.
