Scheduled Mail Status Checks

Need a cron job to check the mailbox status? Run `check_ukpostbox_status` directly from your shell script. This verifies connectivity and ensures your pipeline doesn't fail due to API downtime. It’s perfect for background tasks where you just need a simple pass/fail result piped into a logging system.

Bulk Mail Item Processing

Use the command line to pull all mail records with `list_mail_items`. You can pipe this output through other tools or scripts for batch processing. If you need specific details on a package, your script can call `get_mail_item` sequentially for every ID returned by the list function.

Automated Letter Dispatch via MCP Server

You can write a simple shell wrapper around `send_letter`. This allows you to provide recipient name, full address, and letter content as standard input arguments. The entire process—from variable input to API call—runs headless. You don't need any GUI or browser access.
