When to use it

• Use it when you want the assistant to actually execute generated code rather than just print it.
• Use it when you need a throwaway, isolated environment to run untrusted or experimental code.
• Use it when doing quick data crunching, calculations, or plotting from a chat.
• Use it when prototyping a code-interpreter style workflow in Claude Desktop.
• Use it when you want code execution kept off your local machine for safety.

Quick setup

1. 1Sign up at e2b.dev and copy your E2B API key.
2. 2Open your Claude Desktop config (claude_desktop_config.json) on macOS or Windows.
3. 3Add an mcpServers entry with command npx, args ["-y", "@e2b/mcp-server"], and env E2B_API_KEY set to your key.
4. 4Restart Claude Desktop.
5. 5Verify by asking the assistant to run a small snippet of Python and confirm the sandbox returns output.
