The OpenBudget MCP server works with Claude Desktop (macOS and Windows) and Claude.ai with MCP support enabled. Your data is accessed in real-time — Claude always sees your latest transactions and balances.
Your bank credentials are never shared with Claude. OpenBudget uses Plaid to securely connect to your financial institutions, and the MCP server only exposes read-only transaction and balance data to Claude when you explicitly ask.
