Questions
What is the Compiler Explorer MCP server?
Compile code with thousands of compilers, inspect the assembly, and share godbolt.org links. It is made by @compiler-explorer and listed in the official MCP Registry as io.github.compiler-explorer/compiler-explorer. MCP (Model Context Protocol) is the open standard that lets AI apps like Claude, ChatGPT and Cursor use outside tools.
How do I add Compiler Explorer to Claude?
In the Claude app or claude.ai, open Settings, then Connectors, choose "Add custom connector" and paste https://godbolt.org/mcp. In Claude Code, run: claude mcp add --transport http compiler-explorer https://godbolt.org/mcp
How do I add Compiler Explorer to ChatGPT?
ChatGPT can use remote MCP servers as connectors. In ChatGPT settings, under Apps and Connectors, turn on developer mode if asked, create a new connector and paste https://godbolt.org/mcp.
How do I add Compiler Explorer to Cursor?
Open Cursor settings, go to MCP, choose "Add new MCP server" (or edit ~/.cursor/mcp.json) and add: { "mcpServers": { "compiler-explorer": { "url": "https://godbolt.org/mcp" } } }
Does Compiler Explorer work right now?
