Claude Desktop Switchboard Finance Prompt/prepare_callback

How to: Claude Desktop Switchboard Finance prepare_callback

client:Claude Desktop transport:streamable-http prompt:prepare_callback

Add Switchboard Finance to Claude Desktop

  1. 01

    Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there. 

{
  "mcpServers": {
    "switchboard-finance": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.switchboardfinance.com.au/mcp"
      ]
    }
  }
}
  1. 02

    Save the file and restart Claude Desktop.

  2. 03

    prepare_callback is surfaced in the attachment menu, under the server's name. Unlike a tool, you invoke it deliberately — Claude Desktop will not call it for you.

  3. 04

    If it does not appear, check that Switchboard Finance is connected and that you are looking at its prompts rather than its tools.

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 prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 1 October 2026. A listing does not declare its prompts, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each prompt's arguments.
