Short answer

How can I use AI to manage my physical mail?

Your agent uses Lob to confirm US and international addresses are correct before you send anything. It also pulls live tracking updates so you know exactly when mail arrives. You get a clean list of valid recipients and a clear view of your delivery status.

Where your data lands.

The results of your request.

The AI handles the technical checks and monitoring, then hands you the outcomes.

VALIDATION

Clean mailing lists

The AI checks your recipient data against postal records. You get a list of confirmed addresses ready for shipping.

TRACKING

Live delivery updates

Your agent pulls the latest status for every package or letter. You'll see exactly where your mail is in the delivery cycle.

ERRORS

Flag bad addresses

The AI identifies invalid or incomplete addresses. It highlights these so you can fix them before wasting postage.

HUMAN

Manual corrections

When an address fails validation, the AI flags it for you. You decide whether to skip the recipient or fix the details yourself.

The workflow

What your AI does when you provide address or tracking data.

The AI acts as the bridge between your instructions and the Lob API.

  1. Validate US addresses

    The AI runs your domestic recipient list through the validation tool to ensure they are deliverable.

FAQ

How this task behaves

  • 01

    Can the AI fix a typo in an address automatically?

    No. The AI can identify that an address is invalid, but you must manually correct the information before trying again.

  • 02

    Does the AI send the actual mail?

    No. This MCP only handles address validation and tracking. You must use your existing mail service to physically send items.

  • 03

    Can I verify addresses outside of the US?

    Yes, the AI can verify international addresses using the specific international tool.

  • 04

    Will the AI update my database with tracking info?

    The AI can read the tracking data and tell you the status, but it cannot write directly to your external databases unless you provide a tool for that.

  • 05

    How does the AI know if an address is valid?

    It uses the Lob verification tools to check the address against official postal records.
