Compiler Explorer

Compiler Explorer MCP is a server that connects LLMs to the Compiler Explorer API, enabling them to compile code, explore compiler features, and analyze optimizations across different compilers and languages. The implementation provides three main tools: listing supported programming languages, retrieving available compilers for a specific language, and compiling source code with customizable options and filters. Built with FastMCP and asynchronous HTTP requests, it handles error cases gracefully and supports various compilation parameters, making it particularly valuable for developers and educators who want to compare compiler behaviors, investigate optimization differences, or explore language feature support without leaving their AI assistant conversation.
