Connecting to Claude Desktop App

After running npm run build to build your server, you can test your MCP server using Claude as the client.

After installing Claude for Desktop, the App configuration sits in ~/Library/Application Support/Claude/claude_desktop_config.json. You can use the command code ~/Library/Application\ Support/Claude/claude_desktop_config.json to open this file.

Now, you want to add the following to this json file for your MCP server.

{
    "mcpServers": {
        "alpaca": {
            "command": "node",
            "args": [
                "/ABSOLUTE/PATH/TO/PARENT/FOLDER/alpaca/build/index.js"
            ]
        }
    }
}

Save the file and restart Claude for Desktop. Once you launch you should see the hammer logo with your preloaded MCP toolkit/functions. Enjoy Trading!
