Authorize Claude to access your data

The first time you ask Claude about your finances, it will request permission to connect to OpenBudget . Review and approve to grant read-only access to your transaction data.

When you first ask Claude about your finances, it will show a permission request to connect to the OpenBudget MCP server. Click "Allow" to proceed.

05

Start asking about your finances

You're all set. Copy any prompt below and paste it into Claude, or start a blank conversation.

Try these prompts

What did I spend the most on last month? Break it down by category.
Show me all my subscriptions and how much they cost per year.
How much have I spent on dining out in the last 90 days?
Create a monthly budget spreadsheet based on my actual spending patterns.
What were my biggest single purchases this year?
Compare my spending this month vs. last month — where am I up?

Works with Claude Desktop and Claude.ai

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.

Privacy and security

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.
