Node.js with npx available (the server is launched via npx -y @e2b/mcp-server)

An MCP client such as Claude Desktop (config in claude_desktop_config.json)

What E2B Code Interpreter MCP can do in Claude Desktop

run_code

Run Python code in a secure, isolated E2B cloud sandbox and return the result/output.

Security

Code runs in E2B's remote sandbox rather than locally, which limits host exposure, but the E2B_API_KEY bills against your account and sandboxes can make outbound network calls. Keep the key secret and watch usage.
