Yazio

You can connect Claude or Cursor to your Yazio nutrition data using this MCP server, allowing you to track meals, search foods, view weight trends, and manage nutrition goals directly from your AI assistant. This setup is useful for integrating your personal data with conversational workflows and getting insights without manually switching apps.

How to use

You use an MCP client to connect to the Yazio MCP server. Start the server using the provided command configuration, then configure your MCP client with the server name and credentials. Once connected, you can ask Claude or Cursor to fetch daily summaries, search for foods, log meals, track water intake, review weight history, and manage your nutrition goals. Use natural language prompts like asking for your daily nutrition overview, looking up a specific food, or adding a missing meal directly from your assistant.

How to install

Prerequisites you need before installation: Node.js 18 or newer, and a valid Yazio account.

Install and run the MCP server using the exact command and environment variables shown in the example configuration.

1. Create the MCP configuration in your client with the following details.

Configuration example

{
  "mcpServers": {
    "yazio": {
      "command": "npx",
      "args": ["-y", "yazio-mcp"],
      "env": {
        "YAZIO_USERNAME": "your_email@example.com",
        "YAZIO_PASSWORD": "your_password"
      }
    }
  }
}

Run and test the connection

After configuring your MCP client, start the server via your client’s MCP setup. Then test the connection by initiating a simple query such as requesting your daily summary or searching for a common food item to ensure data returns as expected.

Additional notes

This MCP server uses an unofficial reverse-engineered API to access Yazio data. It is not an official integration, and functionality can change or stop at any time. Your credentials are used only for authentication with Yazio servers.

Security and best practices

• Use a dedicated Yazio account for MCP access if possible, and do not share your credentials beyond your trusted MCP client setup.

• Treat the MCP server as a private integration within your personal AI workflow. Regularly review connected devices and revoke access if you notice any unusual activity.

Troubleshooting

If you encounter authentication failures, verify that the environment variables YAZIO_USERNAME and YAZIO_PASSWORD are correctly set in your MCP client configuration and that the Yazio account is accessible from your network.

If data retrieval stops working, remember this is an unofficial API and may break due to changes on Yazio’s side. Restart the MCP server after updates and re-check prompts in Claude or Cursor for any adjusted endpoints.
