Script financial tasks with Claude Code

Run `list_transactions` inside your CI/CD pipeline to automate reconciliation. It gives you a clean way to handle bank data without a GUI. Pipe the output into your shell scripts or log files. This keeps your finance ops strictly within your terminal workflow.

Monitor accounts from the terminal

Use `get_balance` to check your cash position before running your deploy scripts. It ensures you have the runway for your build. You can set up cron jobs to alert you if your balance drops below a threshold. It is simple, effective, and fast.

Query Mercury records in bulk

Claude Code handles `list_invoices` and `list_recipients` for large-scale data processing. It iterates through pages of results for you. You get the raw data you need for your backend analysis. No browser or manual dashboard required.
