Add Schengen 90/180 Calculator to Claude Desktop
-
01
Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"schengen-mcp": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"https://schengen-mcp.alickzheng618.workers.dev/mcp"
]
}
}
}-
02
Save the file and restart Claude Desktop.

03
Ask for something calculate_stay does. Claude Desktop lists the server's tools on connect and calls calculate_stay itself — you do not invoke it by name.

04
If nothing happens, check the server is running and that Schengen 90/180 Calculator's identifier in your config matches the one above exactly.
Claude Desktop has no remote transport in its config file, so this bridges through mcp-remote. Restart the app after saving. Claude Desktop docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 9 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.
