FAQ
How do I test scripts safely with E2B?
Add the E2B MCP connector once, then paste this prompt into Claude or ChatGPT: "Try installing a weird NPM package in the sandbox and see if it does anything suspicious". Your AI runs it in E2B.
Do I need to code?
No. You install the connector once (a short config or one click), then ask in plain words. The prompt on this page works as-is.
Which AI assistants work?
Claude (Desktop, Code), Cursor, ChatGPT and other MCP clients. The same prompt works across them.
