avenir-mcp

An unofficial, open-source MCP server for YNAB that allows AI agents to read, classify, reconcile, and forecast budget plans. It is read-only by default, ensuring every change is previewed, confirmed by the user, and can be undone. It features 17 tools for tasks like monthly summaries, debt payoff planning, and transaction categorization, designed to be light on YNAB's API quota.
