Runno

Runno is an MCP (Model Context Protocol) server that enables AI assistants and MCP-compatible clients to run code examples in a secure, browser-based or server-based sandbox. Through WASI and WebAssembly, Runno exposes runtime environments for several programming languages (Python, Ruby, JavaScript via QuickJS, SQL via SQLite, C/C++, and PHP-CGI), and supports execution of generic WASI binaries. It is especially useful for programming education, interactive code examples, online coding environments, and developer tools that need safe, isolated code execution. Systems integrating with Runno gain access to these runtimes and sandboxing capabilities, making it ideal for educational platforms, code learning tools, in-browser code editors, and technical documentation sites.
