About MCP Config Builder
A free, fully client-side developer studio designed to make Model Context Protocol server configuration effortless, accurate, and completely private.
What is MCP Config Builder?
MCP Config Builder is an interactive web studio for generating, testing, and sharing configuration files for AI clients including Claude Desktop, Cursor AI, Windsurf, and ChatGPT Desktop.
Everything runs 100% locally in your browser. No configuration payloads, commands, arguments, or environment variables are ever transmitted to any remote server.
Why was it built?
While MCP configuration files use standard JSON, hand-editing them in text editors is prone to syntax mistakes, missing commas, invalid array structures for CLI arguments, and unquoted environment values.
This studio provides interactive form controls, one-click preset templates, live AJV schema verification, and instant copy/download workflows.
