Isolator

Isolator MCP provides secure code execution capabilities for Python, Go, and JavaScript through Docker containerization. Built by Ompragash, it combines a TypeScript MCP server with a Go CLI tool that creates ephemeral containers with strict security constraints including network isolation, read-only filesystems, resource limits, and dropped Linux capabilities. The implementation supports both direct code execution and predefined code snippets, uses tar streaming to copy files into containers without bind mounts to avoid permission issues, and returns structured execution results with stdout, stderr, and status information, making it ideal for AI assistants that need to safely execute user-provided code in sandboxed environments.
