MCP Server for YNAB

Overview

MCP Server for YNAB connects your AI assistant directly to YNAB for financial data access. The server operates read-only by default, with optional reversible writes that you can enable. Any MCP-compatible AI assistant can invoke the server's tools during conversations and agent runs, letting the model decide when to tap into your budget data.

The server runs locally as a Python package installed via uvx mcp-server-for-ynab, communicating over stdio with your system. You'll need to provide your YNAB API key through the YNAB_API_KEY environment variable. Version v0.2.0 is published under the Apache-2.0 license with full source code available at hs737/mcp-server-for-ynab on GitHub.

MCP Server for YNAB belongs in the AI & Agents category and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and others. If you maintain this server, claim this listing to verify ownership and keep information up to date.
