Agent Vendor Controls for Procurement
Every agent purchase is a vendor relationship. Procurement gets the allowlist; agents get blocked from everyone else.
The procurement problem
Agents buy from vendors nobody approved — the equivalent of a rogue PO.
Unknown vendors are the top runaway pattern in the incident database.
Vendor management stops at humans; agents bypass it.
What procurement gets
Merchant allowlists: only approved vendors can be paid.
Category rules mapping spend types to approved vendors.
An audit log showing exactly which vendor got what.
How to deploy
Build the allowlist from your approved vendor list, set category rules, and let new-vendor requests flow through FLAGGED for review.

FAQ
What happens when an agent needs a new vendor?
The purchase is FLAGGED and waits in the approval queue — procurement reviews it like a PO.
Can I block entire categories?
Yes — category rules can block or cap whole spend types (e.g. no crypto, no wire transfers).
