Cursor worldwide eSIM — one eSIM for the whole world price_grid
How to: Cursor worldwide eSIM — one eSIM for the whole world price_grid
Add worldwide eSIM — one eSIM for the whole world to Cursor
-
01
Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"esim-catalog": {
"url": "https://worldwideesim.com/wp-json/worldwideesim/mcp"
}
}
}-
02
Save the file and restart Cursor.
-
03
Ask for something price_grid does. Cursor lists the server's tools on connect and calls price_grid itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that worldwide eSIM — one eSIM for the whole world'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 28 October 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.
