What the assistant can do

SellDeck speaks the Model Context Protocol — the open standard AI assistants use to operate software. Point Claude or Cursor at your account and manage inventory, listings, and fees in plain English instead of clicking through menus.

Ask anything: live inventory counts, eBay order and fee history, listing status.
Single changes: reprice a listing, update quantity, end a listing, edit an item.
Bulk jobs: relist hundreds of ended auctions as Buy It Now, roll 1-day handling across the store, assign store categories — queued in the background with live progress.

Step 1: Generate your token

Log in to SellDeck and open Settings. Find the AI Assistant (MCP) card and click Generate Token. Copy it immediately — it is shown once and expires in 90 days (regenerate any time for a fresh 90 days).

Requires the Pro plan or higher. Lower tiers see an upgrade prompt on the same card.

Step 2: Connect Claude Desktop

Open Claude Desktop → Settings → Connectors → Add custom connector:

URL: https://selldeck.io/api/v1/mcp
Auth: Bearer token — paste the token from Step 1.

Type "How many items do I have listed on eBay right now?" to confirm it works.

Step 2b: Connect Cursor / Claude Code

Add this to your MCP config file:

{
  "mcpServers": {
    "selldeck": {
      "url": "https://selldeck.io/api/v1/mcp",
      "headers": {
        "Authorization": "Bearer PASTE_TOKEN_HERE"
      }
    }
  }
}

8 prompts to try first

"How many items do I have listed on eBay right now, and what's the total value?"
"What were my eBay fees last month, broken down?"
"Show me everything under $10 that's been listed over 60 days."
"Reprice item 10212 to $49.99."
"Relist my unsold VHS tapes to the VHS store category." — dry-run first; say yes to queue it.
"Set all active listings to 1-day handling." — the Top Rated Seller prerequisite.
"Which of my rare books have no ad campaign? Draft ad rates for them."
"End listing 178502578542." — requires typing the confirmation.

Safety: what it will never do

Auction items with bids are never touched. Revises, ends, and relists all skip them automatically.
Deletes and listing-ends need typed confirmation (delete {id}, end {itemId}) — a stray sentence can't wipe inventory.
Bulk work shows a dry-run first. Nothing executes until you say so, and progress is pollable at any time.
No buyer messaging, no bidding, no data scraping. It only sees and touches your own inventory.
Lost your token? Revoke it in Settings → AI Assistant. Tokens also expire on their own after 90 days.

Troubleshooting

"No auth token" / 401: the Bearer token is missing or expired. Regenerate it in Settings and update your connector config.
"Write rate limit exceeded": 20 writes/minute per user. Wait a minute and retry — bulk jobs throttle themselves.
A bulk job seems stuck: ask for bulk_status with the batch ID. The queue drains roughly 20 jobs/minute; a 200-item batch takes about 10 minutes.
"Upgrade prompt": AI assistant access needs Pro or higher.
