YNAB

Connects Claude to YNAB's API so you can manage your budget through conversation. You get tools to list budgets, create and approve transactions, check category spending, and get budget summaries showing underfunded categories. Requires a YNAB personal access token stored as an environment variable. The main workflows here are adding transactions by describing purchases in natural language, approving pending transactions from unapproved lists, and getting spending overviews without opening the YNAB interface. Built with mcp-framework and wraps the standard YNAB REST API endpoints for budgets, transactions, and accounts.
