For installation methods and deployment options, see Installation . For implementation-specific details, see JavaScript Implementation and Python Implementation . System Overview The E2B MCP Server provides a dual-language implementation of a Model Context Protocol server that enables secure code execution through E2B sandboxes. Both implementations expose identical functionality through the MCP protocol while using language-specific libraries and patterns.

About
Official E2B MCP server giving agents secure code execution in cloud sandboxes. Agents run Python and JavaScript in isolated Firecracker-backed VMs — install packages, execute scripts, inspect output — without touching the host machine. The run_code tool wraps E2B's sandbox SDK; sandboxes spin up in ~150ms and are destroyed after use. The canonical safe-code-execution primitive for MCP-native runtimes. Best for data analysis agents, code-interpreter features, and running untrusted AI-generated code. Limitation: requires an E2B API key; long-running or stateful workloads need the full SDK rather than the MCP wrapper.
