Gemini CLI resOS MCP by usefulapi resos_update_booking
How to: Gemini CLI resOS MCP by usefulapi resos_update_booking
Add resOS MCP by usefulapi to Gemini CLI
-
01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"resos": {
"httpUrl": "https://resos.usefulapi.io/mcp"
}
}
}-
02
Save the file and restart Gemini CLI.
-
03
Ask for something resos_update_booking does. Gemini CLI lists the server's tools on connect and calls resos_update_booking itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that resOS MCP by usefulapi's identifier in your config matches the one above exactly.
Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI 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.
