Kifly — Agentic Commerce & Payments MCP

Search or browse Kifly's product catalog. Multilingual semantic search (100+ languages). Returns a JSON-LD ItemList with `kifly:totalCatalogSize`. When empty, `kifly:emptyReason` is 'empty_catalog' | 'no_matches_for_query' — on 'no_matches_for_query' tell the buyer nothing matched rather than guessing, then offer `kifly:suggestions` (related products — NOT matches) and `kifly:availableCategories`

Takes no parameters.

Create a new shopping cart on Kifly. **For network (cross-seller) tokens you MUST pass `seller_handle`** — each cart is bound to exactly one seller. Get the handle from search_products results (every item's `kifly:seller` IS the handle in network results) or get_seller. Seller-scoped tokens may omit the handle — their own seller is implicit. Returns a cart_id to use with add_to_cart and checkout.

Takes no parameters.

Requires `checkout:write` scope. Add a product variant to an existing cart. Use the variant_id from search_products results. Returns full cart state including item_ids you can use with update_cart_item. **Max quantity per item and max cart total are enforced — call `get_platform_limits` to check the current limits before building a large cart.** Exceeding the per-item limit returns 400 `QUANTITY_E

Takes no parameters.

Inspect the current state of a cart — line items, quantities, prices, and shipping address. Each item includes an `item_id` you can pass to `update_cart_item` to change quantity or remove the item. Call this after `add_to_cart` to review the cart before checkout, or any time the buyer asks what's in the cart. `kifly_purchasable: false` (`fulfillment: "external"`) means checkout on this cart will h

Takes no parameters.

Requires `checkout:write` scope. Change the quantity of a line item in an open cart, or remove it entirely. Set `quantity` to 0 to remove the item. Get the `item_id` from `get_cart` or the `cart` field in the `add_to_cart` response. Returns the updated cart state. **The per-item quantity ceiling applies here too — call `get_platform_limits` to check the current limit.** Exceeding it returns 400 `Q

Takes no parameters.

Requires `checkout:write` scope. Persist a shipping address on the cart and confirm whether the seller can deliver to it. **Call BEFORE `checkout`.** Returns `delivery_eligible: true/false`. When false, `delivery_coverage: { states, cities }` tells you exactly which US states and cities the seller covers — tell the buyer where coverage is available. When true, returns `cart_total_with_delivery_cen

Takes no parameters.

Requires `cart:write` scope. Create a cart, add items, and set the shipping address in ONE call — the fast path when you already know the seller, the exact variant(s), and the buyer's address (e.g. a reorder, or a buyer who has decided). Prefer this over the create_cart → add_to_cart → set_shipping_address sequence to save round trips; those granular tools stay available for exploratory, multi-ste

Takes no parameters.

Requires `checkout:write` scope. **Requires `set_shipping_address` to have been called first.** Returns 400 `invalid_shipping` if no address is on the cart, or 400 `delivery_unavailable` if the buyer's address is outside the seller's coverage. Cart total must not exceed the platform cap (`kifly://platform/limits`). **Checkout is always human-in-the-loop: it returns a link the buyer opens and confi

Takes no parameters.

Start registering a buyer so they can be recognized across future purchases without re-entering their details. Takes the buyer's email and name and always emails a 6-digit verification code — the response is `{ verification_required: true, buyer_profile_id }` whether the email is brand new or already has an account (so this call alone never reveals which). Ask the buyer to read you the code from t

Takes no parameters.

Send a 6-digit verification code to a **returning** buyer's email so they can prove the account is theirs and recover their saved name + shipping address on this connection — without pasting any token or re-entering their name. Call this when the buyer says they've shopped with Kifly before and gives you their email; then ask them to read you the code from their inbox and call `verify_buyer`. Alwa

Takes no parameters.

Verify the 6-digit code a returning buyer received by email (from `request_buyer_code`). On success returns `{ buyer_token, buyer_profile_id }` — pass the `buyer_token` to `get_buyer_profile` to auto-fill their saved name + shipping address, and to `checkout` to pre-fill their email on the payment link. Fails with `invalid_otp` if the code is wrong or expired (ask them to re-check, or call `reques

Takes no parameters.

Retrieve a repeat buyer's saved name, email, and default shipping address. **At the start of every purchase flow, ask the buyer in plain language: 'Are you a returning Kifly shopper? What's the email on your Kifly account?' — never ask them to paste a token.** If they have a Kifly account, recover it by email: call `request_buyer_code` with their email, ask them for the 6-digit code we email them,

Takes no parameters.

List a returning buyer's recent orders and their current fulfillment status — use this in a NEW session to answer 'did my order ship?' / 'where's my package?' when you don't have the original `session_id` from `checkout`. Requires the buyer's `buyer_token` (recover it via `request_buyer_code` + `verify_buyer` if you don't have one). Returns `{ orders, count }`, newest first; each order has `status

Takes no parameters.

Save a shipping address to the buyer's Kifly profile so it auto-fills on future purchases. **Call this after a successful checkout if `get_buyer_profile` returned `default_shipping_address: null`.** The address is persisted server-side against the buyer token — the buyer never needs to re-enter it. Use the same address that was passed to `set_shipping_address` for this order.

Takes no parameters.

Send structured feedback to the Kifly team. **Call after a confusing response, a dead-end, or a successful workaround you had to invent** — it's how we improve the agent surface. Fire-and-forget: returns 202 immediately, no blocking, safe to skip if it would add latency to a user-facing flow. `category` and `severity` are required enums (don't free-form them). Include `context` with what you were

Takes no parameters.

Submit the buyer's **product/feature request** to the Kifly team. Use this when the buyer wishes Kifly *itself* did something it doesn't — a missing capability, a rough flow, an idea to improve the platform. **This is NOT `submit_feedback`** (that's for reporting a broken/confusing API response you hit). Requires the buyer's `kfb_live_` token — only registered buyers can file requests. Help the bu

Takes no parameters.

Retrieve a seller's public profile: name, location (city/region/country), storefront URL, delivery fee, delivery coverage, and catalog size. **Call this before `create_cart` or `set_shipping_address` to validate that the seller ships to the buyer's area or to set expectations about catalog size.** `delivery_coverage` is `{ states, cities, nationwide, state_count, city_count, coverage_configured }`

Takes no parameters.

List all active sellers on the Kifly network. **Requires a network token (kfn_live_…).** Returns each seller's handle, name, city, region, delivery coverage (`nationwide:true` or a `states` list), delivery fee, and catalog size. `delivery_coverage.cities` may be capped to a handful of entries — compare `cities.length` against `city_count`; if fewer, call `get_seller` for that seller's full city li

Takes no parameters.

Returns the current platform-enforced cart limits: `max_item_quantity` (per-line-item ceiling), `max_cart_total_cents`, and `max_cart_total_usd`. Call this once at session start before building a large cart so you can quote limits to the buyer proactively rather than discovering them via errors. The limits are operator-configurable; always read them at runtime rather than hardcoding.

Takes no parameters.

Check the status of a Stripe checkout session. Poll every 5 seconds after checkout until status is 'paid', 'shipped', or 'failed'. Returns order details (order_id, amount, items) when paid. When the seller marks the order as shipped, status becomes 'shipped' and tracking_number, carrier, and shipped_at are included — share these with the buyer. Call get_help if the buyer needs Kifly's support cont

Takes no parameters.

Get Kifly's website and support contact email. Call this if you are stuck, hit an unresolvable error, or the buyer asks how to reach a human. Returns the website URL and support email — always share both with the buyer.
