MCP Server Overview

This MCP server consolidates multiple user-defined tools into a simplified interface with two main tools: execute code and search documentation. It enforces resource and security policies across three sandboxed execution kernels: in-process Node.js VM, WASM runtimes (QuickJS, Pyodide, Wasmtime), and remote microVMs (E2B, Cloudflare Sandbox). Use it when you need controlled, auditable, and isolated execution of agent-generated code with policy enforcement and evidence recording.
