Deno Code Executor

This MCP server provides secure TypeScript and JavaScript code execution through Deno, enabling AI assistants to run code snippets in isolated processes with configurable permissions. Built by Cong using TypeScript with the MCP SDK and Deno runtime, it executes code by writing to temporary files and running them in separate Deno processes, with permission configuration handled at server startup rather than per-execution for security. The implementation includes automatic cleanup of temporary files, helpful error messages for permission issues, and support for both basic sandboxed execution and specific permission grants (network, file system, etc.), making it valuable for code testing and validation, educational programming assistance, and automated script execution workflows that require secure code isolation.
