Once your store is connected, an assistant can help you investigate prices in your own TCGplayer inventory and prepare a pricing-rule change. Asking it to look is read-only. A reviewed rule proposal is a separate workflow; a chat request cannot make an arbitrary manual override to one card’s price. For the broader operating routine, read how Hoard’s founder uses AI to run his TCGplayer store.

​
Step 1: Connect your assistant

Follow the setup guide for Claude or ChatGPT. You can also use the client-agnostic store connection overview.

​
Step 2: Find a pricing gap

“Which cards in my own inventory are priced below market? Show the listed price, market price, and gap. Don’t change anything.”
This is a read of your Hoard store. Start with the underpriced-inventory walkthrough if you need to distinguish your listings from market-wide cards to buy.

​
Step 3: Explain the cards that matter

“Why is this exact printing and condition priced this way? Show the governing rule, price source, floor or cap, and any blocker. Don’t change anything.”
The card-price explanation guide covers the stored rule match, a live rule evaluation, and what to check if they disagree. A price gap by itself is not proof that a listing should move; condition, finish, a lock, and your strategy matter.

​
Step 4: Prepare a rule change if the pattern warrants it

If the problem spans multiple cards, ask for a pricing-rule proposal, such as separate treatment for bulk, foils, and protected inventory. Hoard gives you a review page with the affected cards and impact. The proposal does not apply until you approve it there. If only one listing needs a manual price lock or one-off override, use the Hoard dashboard. Arbitrary per-card overrides through the assistant are not shipped today. Some Smart Actions can directly change one card when accepted, so read the action and the full capability map before you accept one.

​
Step 5: Check freshness and the result

If the answer does not line up with your dashboard, check sync health before assuming the store or the assistant is wrong. Once an approved change and the next sync have run, inspect the resulting pricing state in Hoard. The assistant’s proposal is not by itself proof that TCGplayer accepted a later price push. For public card market-price lookups without your store data, use tcgmcp instead. It cannot explain your private pricing rules or change your listings.
