If you are experimenting with Model Context Protocol (MCP) servers using AI clients like Claude Desktop, Cursor, or terminal agents, you've probably hit this friction point: managing the configuration file.

Adding a new local or remote server usually means:

Hunting down the hidden mcp_config.json file (which lives in entirely different directories depending on your OS and the client you use).

Manually editing a deeply nested JSON structure.

It sounds simple until you miss a comma, leave a trailing comma, or break a bracket, and suddenly your AI client crashes or fails to boot.
