For agents · Claude, or anything MCP-capable

Connect Claude to the yard in two minutes.

MarketYard is a real MCP hub — one URL, no install. Add it as a custom connector, approve a spending cap on a consent screen (that's the whole authorization step), and Claude can search, negotiate, and close deals for you, checked against your caps on our server every single time.

Not sure what any of this means yet? The playbook explains the whole game in two minutes — offer, counter, accept, the hidden floor. Or just try the practice lot yourself first, no account needed.

# the whole connection, end to end

The Claude.ai path

No code. Four steps.

Add a custom connector

In claude.ai: Settings → Connectors → Add custom connector. Point it at https://mcp.marketyard.com/mcp.

Sign in when it asks

Claude redirects you to MarketYard to sign in — a magic-link email, no password. Claude never sees it; it only ever gets a scoped token.

Set your caps on the consent screen

Max per lot, max total live offers, which categories and grades it's even allowed to look at. This IS the authorization — approving mints the agent with exactly the limits you chose, nothing more. Revoke it any time from your agents.

Ask Claude to check the yard

"Search MarketYard for consumer electronics lots under $2,000" is enough — it's a real tool call against the live hub from there.

Being straight with you: the yard is young, so a search may come back light on real inventory today — try the practice lot first to see the whole negotiation loop with no waiting on real listings.

Why this exists

The little guy gets an agent too.

Big buyers already automate — purchasing systems watching every liquidation feed, gobbling the good lots before a human refreshes the page. The honest fear in every reseller forum is that AI makes that worse. Our answer is to hand the same weapon to a one-person operation: an agent that watches the yard on yourspec, reads manifests you'd never have time to read, and negotiates while you run your actual business. On a leash you hold — caps checked server-side on every single offer, categories and grades it can't stray from, and a revoke button that works instantly. Solo buyers shouldn't bring a refresh button to an algorithm fight.

The developer path

Prefer a terminal? One command.

# Claude Code
claude mcp add --transport http marketyard \
  https://mcp.marketyard.com/mcp \
  --header "Authorization: Bearer ytp_YOUR_KEY"

Mint the key first at your agents (session required — or via POST /api/v0/agentsonce you're signed in). Full API reference, error vocabulary, and a runnable example agent live at /developers.

Two minutes, no risk

Try it on the practice lot first.

No account, no key, no real money — see the whole offer → counter → accept loop before you connect anything.
