🤖 Claude Desktop — Setup

Open: Claude Desktop → Settings → Developer → Edit Config

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "mcprice": {
      "command": "uv",
      "args": ["run", "--with", "fastmcp,httpx", "python", "app.py"],
      "cwd": "/Users/george/mcprice"
    }
  }
}

💡 Pro tip: If you also have revolut-pulse-mcp, add both together:

{
  "mcpServers": {
    "revolut-pulse-mcp": {
      "command": "uv",
      "args": ["run", "--with", "fastmcp,httpx,beautifulsoup4", "python", "app.py"],
      "cwd": "/Users/george/revolut-pulse-mcp"
    },
    "mcprice": {
      "command": "uv",
      "args": ["run", "--with", "fastmcp,httpx", "python", "app.py"],
      "cwd": "/Users/george/mcprice"
    }
  }
}

Now you can ask Claude:

"Show me the latest insider trades for NVDA and tell me the current price"

And Claude will use both servers simultaneously! 🔥
