Cline RIFFCADE play_game

How to: Cline RIFFCADE play_game

client:Cline transport:streamable-http tool:play_game

Add RIFFCADE to Cline

01
Open ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "arcade": {
      "url": "https://mcp.riffcade.com/mcp"
    }
  }
}

02
Save the file and restart Cline.
03
Ask for something play_game does. Cline lists the server's tools on connect and calls play_game itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that RIFFCADE's identifier in your config matches the one above exactly.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 13 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.
