How to Use the Lob MCP in Windsurf

Q: Can Windsurf use Lob to send checks?

Yes. You just instruct Cascade to use the createcheck tool. It handles the API call and reports back once the check is queued for printing.

Q: Does Lob work with Windsurf for address verification?

It does. You can ask Cascade to run verifyusaddress on your mailing list. It cleans the data and flags any errors before you send a single letter.

Q: What happens if a mail piece fails to deliver?

You use getmailtracking to pull the status logs. The tool returns the delivery state, so you can decide if you need to resend the item.

Send physical mail directly from your Windsurf editor with automated address verification and tracking.

Automate physical mail in Windsurf

Cascade can take a list of customer records and use `verify_us_address` to clean your data before anything gets printed. It stops you from wasting budget on undeliverable mail. Once the addresses are clean, your agent fires off requests to `create_postcard` or `create_letter` without you leaving the chat. It keeps your physical and digital workflows in the same loop.

Track mail status inside the IDE

You don't need to check a dashboard to see if a check arrived. Cascade uses `get_mail_tracking` to pull the current status of any `create_check` job directly into your terminal output. This gives you instant visibility into your fulfillment pipeline. You see exactly when a piece of mail hits the sorting facility or reaches the final destination.

Manage international mailings

If you have global customers, `verify_intl_address` lets you confirm destination formats before you commit to a print run. It prevents the common errors that usually hold up international shipments. Windsurf handles the logic for these calls automatically. You define the target, and the server validates the data before the physical process begins.
