 This entire project was vibe-coded by an AI. It is 100% slop code. Use it at your own risk.
 
+## 🚨 SECURITY WARNING
+**This server is designed to be run on `localhost` ONLY.** 
+It contains tools (such as `read_image` and `list_directory`) that allow the LLM to read arbitrary files from your filesystem. If you expose this server to the network or a public IP, any user or compromised AI could potentially read sensitive system files (e.g., SSH keys, `/etc/passwd`). 
+**NEVER run this server on a public-facing IP without implementing strict path validation.**
