AI Access

Search our marketplace with your AI assistant.

Midnight Merchant speaks the Model Context Protocol (MCP) — the open standard AI assistants use to work with live data. Connect Claude, ChatGPT, or any MCP-compatible chatbot and ask it to hunt cards for you: real listings, real prices, real Australian sellers, straight from the marketplace — no scraping, no stale data.

Connect a chatbot

One URL. No API key. Free.

Our public MCP endpoint is:

https://midnightmerchant.com.au/api/mcp

• Claude Code (terminal)

  One command, then just ask it to search:

  claude mcp add --transport http midnight-merchant https://midnightmerchant.com.au/api/mcp

• Claude (web & desktop)

  Go to Settings → Connectors → Add custom connector, name it “Midnight Merchant”, and paste the endpoint URL above. No login or API key is needed.

• ChatGPT

  In Settings → Connectors, enable developer mode if prompted, choose Add connector / Custom MCP server, and paste the endpoint URL. Approve the two read-only tools when asked.

• Any other MCP client

  We speak standard MCP over streamable HTTP. For clients configured with JSON:

  {
    "mcpServers": {
      "midnight-merchant": {
        "type": "http",
        "url": "https://midnightmerchant.com.au/api/mcp"
      }
    }
  }

What your assistant can do

Two tools, plain-English prompts

• search_listings

  Searches live, in-stock listings by name, game, set, rarity, product type (singles, playsets, sealed, Mixed Lots) and price range. Supply an Australian postcode and results include the distance to each seller — or sort nearest-first for local pickup.

• get_listing

  Fetches the full public details of one listing — description, photos, condition and grading, shipping cost, seller rating and shop link — so your assistant can compare options and hand you a direct link to buy.

For sellers

List cards by chat

Sellers get a second, sign-in-protected connection. Add it to your assistant, approve it once with your normal Midnight Merchant login, and then just say what you want to sell — your assistant finds the exact card in our catalog, confirms the price with you, and creates the listing with official stock art. Add your own photos later from the edit page.

https://midnightmerchant.com.au/api/mcp/seller

Add it exactly like the search connector above — same steps, this URL — and your assistant will pop open a Midnight Merchant sign-in when it first connects. In Claude Code:

claude mcp add --transport http midnight-merchant-seller https://midnightmerchant.com.au/api/mcp/seller

• You stay in control

  Connecting uses the same secure sign-in as the site, and you approve exactly what the assistant may do on a consent screen. It can create listings and hide or show them — it can never buy, message anyone, or change your account, and you can revoke access at any time.

• Catalog-matched listings

  Singles, playsets and sealed products. Every listing is matched to our card catalog, so the name, set, card number, rarity and stock image are always right — no typos, no wrong-set mixups. You supply the price, quantity and condition.

• Ready when you are

  Listing by chat needs a seller account with PayPal connected — the assistant checks for you and points you to seller setup if anything’s missing. Try: “List my near-mint Charizard ex from Obsidian Flames for $70.”

Browsing with an AI browser?

It already works — nothing to set up

Midnight Merchant supports WebMCP, the emerging web standard for AI-enabled browsers. If you browse with an agentic browser (like Chrome 149+ with AI features), the same search tools are offered to your browser’s assistant automatically the moment you land on the site. Just ask it — “find me sealed One Piece boxes under $150” — and it searches through a structured API instead of squinting at the page.

The fine print

Your account, your rules

• The search connector is strictly read-only. Listing by chat requires your explicit sign-in and consent — and even then, no assistant can ever buy, message, or change your account.

• Search returns only what any visitor already sees on a listing page. Checkout always happens here, by you.

• The endpoint is rate-limited to keep it fast for everyone. Building something bigger? Talk to us.
