Frequently asked questions

Is this tied to official MCP packages?
The template uses common @modelcontextprotocol server names; confirm versions and env vars in each server’s docs.
Where do I put the file?
Claude Desktop uses its app config path; Cursor expects .cursor/mcp.json — follow your editor’s latest instructions.
