Short answer
How can I send physical checks using my AI?
Your agent uses the Lob MCP to print and mail checks automatically after you approve an invoice. This moves the process from a digital chat to a physical mailbox. You'll see the specific outcomes below.
The outcomes.
Where your payments land.
Once you trigger the process, these are the results.
DIGITAL
Check data prepared
The AI pulls the payee and amount from your approved invoice. It formats everything so the check is ready for printing.
PHYSICAL
Mail is triggered
Lob receives the instruction and handles the printing and postage. A real check is sent to the recipient's address.
HUMAN
Approval required
The AI won't send money on its own. You must review the invoice details and confirm the payment before the check is created.
TRACKING
Delivery status
You can ask your agent for updates on the check. It tracks the movement of the mail through the Lob system.

What your AI does when an invoice is approved.
The AI takes over the manual paperwork once you've verified the bill.

How this task behaves
- 01
Can the AI send a check without me looking at it?
No. You must approve the invoice or the check details before the AI executes the command.
- 02
Does the AI handle the postage costs?
The AI triggers the request, but the actual postage and printing costs are handled through your Lob account.
- 03
Can my AI change the amount on a check after it's sent?
No. Once the check is created and sent to Lob, the transaction is final.
- 04
What happens if the address is wrong?
The AI uses the address provided in your prompt or the invoice. It cannot verify if a person actually lives at that address unless that data is in your files.
- 05
Can the AI print checks at my office?
No. This MCP uses Lob to print and mail checks through their professional mail services.
