How to: Cursor EsimTao — Global Travel eSIM Data Calculator, Advisor & Device Checker calculate_esim_data_usage
Add EsimTao — Global Travel eSIM Data Calculator, Advisor & Device Checker to Cursor
-
01
Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"mcp": {
"url": "https://esimtao.com/api/mcp"
}
}
}-
02
Save the file and restart Cursor.
-
03
Ask for something calculate_esim_data_usage does. Cursor lists the server's tools on connect and calls calculate_esim_data_usage itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that EsimTao — Global Travel eSIM Data Calculator, Advisor & Device Checker's identifier in your config matches the one above exactly.
Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 11 November 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
