Connect SP3ND to your agent.
Add SP3ND once, then shop Amazon, eBay, and live Collector Crypt cards from any new chat. Checkout uses a separate Solana wallet approval. Pay SP3ND in USDC; our team manually purchases collectible cards and transfers them to your wallet.
One-time connection
Remote MCP · OAuth
Leave authentication fields blank.
No bearer token, API key, secret, or custom headers. Your client discovers SP3ND OAuth automatically after you save.
Set it up once
Four steps, then every new chat is ready.
In Codex Desktop, open Settings → Plugins → Add → MCP. Other remote MCP clients use the same URL and OAuth flow.
Add the MCP
Open your agent client's settings, find Plugins or MCPs, and choose Add MCP. Name it sp3nd_mcp.
Paste the server URL
Paste the production URL above. Leave bearer token, API key, secret, and custom header fields blank.
Authorize your wallet
Save the MCP and follow the OAuth prompt. Connect a Solana wallet and sign the login message—it proves ownership and does not move funds.
Start with a link
In any new chat, paste an Amazon or eBay link to shop, or a Collector Crypt asset link to buy a card with USDC.
Installation is one-time. Once SP3ND is connected, new chats in that client can use it automatically.
Wallet extension in another browser?
On the SP3ND authorization page, choose Continue in another browser. Copy the link into the browser where your wallet is installed, accept it, connect, and sign.
Shop products and collectible cards from chat.
SP3ND searches live Collector Crypt listings, quotes current prices, and lets you pay in USDC for manual wallet delivery. Amazon and eBay flows also create unpaid orders, open checkout, and report fulfillment.
- Search live Collector Crypt card listings and prices
- Quote current product, tax, and shipping totals
- Create an unpaid order after you confirm the quote
- Show the cart in chat, then open secure wallet approval
- Pay SP3ND in USDC for cards with your separate wallet approval
- Track physical orders and manual card delivery to your wallet
Collector Crypt payments go to SP3ND. Our operations team manually buys the exact card and transfers it to your wallet. Paid means payment received, not delivered. Discovery and quotes do not reserve a card; an unavailable listing may require review and a refund.
Try it in a new chat
Paste a link. Ask for a quote.
The longer prompt makes the approval boundary explicit. Once connected, you can also ask SP3ND to buy an Amazon/eBay product or buy a Collector Crypt card with USDC for manual wallet delivery.
Secure by design
Your wallet stays in control.
Login is not payment
The login signature only proves wallet ownership. It creates no transaction and moves no funds.
Every payment is separate
Checkout requires a new wallet approval. SP3ND and your agent cannot sign or pay for you.
No service credentials
You never provide Partner API keys, a private key, or a seed phrase. PayBox is not required.
Disconnect anytime
Remove SP3ND from your agent client whenever you want to revoke the connection.
Do I install SP3ND for every chat?
No. Installation is one-time for that agent client or account. Once connected, new chats can use SP3ND automatically.
Do I need PayBox or an SP3ND Partner API account?
No. Connect the MCP and authorize your own Solana wallet. SP3ND keeps its service credentials on its servers.
Can the agent spend without me?
No. The agent can prepare the purchase flow, but payment requires your separate wallet approval at checkout.
Where can I shop?
Amazon and eBay product ordering is supported. You can also search eligible live Collector Crypt listings, get a server-priced quote, and pay SP3ND in USDC. SP3ND manually purchases the exact card and transfers it to your wallet; payment received is not the same as delivery.
