Use the droplinked hosted MCP server to discover verified merchants and inventory, run an agent-initiated checkout (cart, quote-and-hold, payment), and read droplinked's onchain trust fabric — brand, credit-risk, and repayment attestations — as source-grounded, verification-first commerce context.

An agent already created a cart and needs to change an item's quantity from 1 to 3, as well as apply a promotional coupon. Which specific tools should be called for these cart edits?
| Checked | Without skill | With skill |
|---|---|---|
| Names cart.updateLineQuantity for updating item quantities. | Missed | Passed |
| Names cart.applyDiscount for applying promotional codes. | Missed | Passed |

droplinked is onchain agentic commerce exposed to Codex over a hosted MCP
server at https://mcp.droplinked.com/mcp (streamable HTTP). Reach for it when
a task needs to find real, in-stock merchandise from KYB-verified merchants,
transact on the user's behalf, or read the onchain trust state behind a brand,
a lender, or a merchant's credit history.
droplinked is verification-first: every discovery and product result carries a verification block (brand-verified flag, KYB tier, EAS attestation UID/chain). When you cite a merchant, product, or recommendation, surface that trust state — per the droplinked model, the agent IS the verification UX.
The server uses per-tool, two-tier auth:
X-MCP-API-Key. The mutating tools (checkout,
payment, cart edits, and lending/attestation actions) return 401 without a
valid key. The key is supplied from the DROPLINKED_MCP_API_KEY environment
variable — never hardcode it. Request a write key from droplinked
([email protected]).A subset of write tools (lending applications, partner referral, business-buyer
search) additionally require a two-header model: X-MCP-API-Key authorizes the
request to the server, and Authorization: Bearer <agent-or-merchant-jwt>
carries the caller's identity to backend tools guarded by AgentIdentityGuard.
