Comment Comment by est slightly related, if you need a safe python sandbox instead of eval(), you can tryeval(YOUR_CODE.replace('__', ''), {'__builtins__': None}, {})I saw this trick on reddit many years ago and wrote a blog last month https://blog.est.im/2026/stdout-09I wasn't able to crack this sandbox, and neither could opus-4.6-thinking.This sandbox won't protect you from DoS, but I think it's reasonably safe to use it for AI tool calls. Just expose your MCP/RPC methods in the last {} and you are good. parent est 7 months ago
