The Exact Prompt to Fix "My AI Tool Can't Access My Localhost"
By Karo
Your AI agent cannot see your localhost because it runs in a sandbox. A cloud micro-VM, an isolated process, or a remote container. Different machine. Different "local".
Three fixes exist. Tunnel the port with Cloudflare Tunnel or ngrok. Run the project inside the agent's sandbox. Or deploy to a temporary public URL.
Send the agent the diagnostic prompt and let it tell you which fix applies. The right answer depends on the tool, not the project.
