Code Runner
The Code Runner MCP Server enables execution of code snippets in over 40 programming languages including JavaScript, Python, Go, Ruby, Rust, and many others, providing output results directly through the Model Context Protocol. The server solves the problem of testing and running code without leaving an AI interface, supporting languages from common choices like Python and JavaScript to specialized ones like Julia, Haskell, and Clojure. It can be deployed via npx or Docker and integrates with VS Code and Claude Desktop.
