Installation

Requirements

• Node.js v18 or higher

• Claude Desktop

1. Open the Claude config

Claude Desktop → Settings → Developer → Edit Config

2. Paste this into the file

{
  "mcpServers": {
    "dolar-argentina": {
      "command": "npx",
      "args": ["-y", "dolar-argentina-mcp"]
    }
  }
}

If you already have other MCPs configured, add only the "dolar-argentina" block inside "mcpServers".

3. Restart Claude Desktop

Close it completely (Cmd+Q on Mac / Alt+F4 on Windows) and reopen it. The server should appear active in Settings → Developer.

That's it. There is no need to clone the repo or install anything manually — npx takes care of downloading and keeping it updated.

Recommended usage

So that Claude queries prices automatically without you having to ask every time, add this in Claude → Settings → Profile → Personal preferences:

Cuando trabajés con presupuestos, precios o tablas comparativas en pesos y dólares,
consultá siempre el MCP dolar-argentina para usar los valores actualizados del día
(blue, oficial, MEP, etc.) sin que yo tenga que pedirlo explícitamente.

Usage examples

Once installed, you can ask Claude things like:

• "Make a comparison table of these services in USD and convert them to pesos at the blue and official rates"

• "How much does this product cost in dollars at today's price?"

• "Create a budget in ARS using the MEP dollar"

• "How much is $500 USD at the blue rate right now?"
