The Ynab MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Ynab account. It provides structured and secure access to your budgeting data, so your agent can perform actions like tracking expenses, creating and adjusting budgets, fetching transaction history, and analyzing spending patterns on your behalf.

• Automated transaction tracking: Let your agent fetch, categorize, or summarize recent transactions to keep your spending up to date.
• Budget creation and adjustment: Instruct your agent to set up new budgets, update existing categories, or reallocate funds between envelopes as your needs change.
• Spending analysis and reporting: Have your agent analyze your expenses, highlight trends, or generate summaries to help you understand where your money goes.
• Goal monitoring and progress updates: Ask your agent to track progress toward savings or debt payoff goals, and notify you of milestones or needed adjustments.
• Account and balance synchronization: Enable your agent to pull up-to-date balances from multiple accounts, ensuring your budget always reflects the latest financial picture.
