Connect your assistant

This guide shows you how to connect an AI assistant such as Claude or ChatGPT to your finances in guito, so you can ask about your data from the assistant you already use. You connect by pasting one URL and signing in once: no extra setup inside the app.

Available on the Plus plan. For what assistants can do once connected, see What are AI assistants.

ChatGPT custom connectors (apps) are available on all plans. By default the assistant reads your data; logging entries requires the guito Plus plan and always asks for your confirmation.

Works with any MCP-compatible client.In Claude Code, add the server with a single line:

claude mcp add --transport http guito https://guito.pt/api/mcp

In Cursor, VS Code and other editors, add the server to your client’s MCP configuration file (mcp.json):

{
  "mcpServers": {
    "guito": {
      "url": "https://guito.pt/api/mcp"
    }
  }
}

The Gemini app does not yet support adding custom MCP connectors.

Check that it worked

In a conversation, ask the assistant a question about your data, for example “What is my net worth?”. If it answers with your figures, the connection is working.
