**info** The word "credentials" in `submit_feedback` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention)) ```untrusted-server-text The description mentions "credential". description: "...p-agent.profile` and this works with no credential at all. **Call after a confusing respon..." ``` - **warn** Annotations that disagree with the tool in `get_seller` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict)) ```untrusted-server-text The server marks "get_seller" read-only (readOnlyHint: true), and its own name, description or input give the class "write". annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "get_seller" says "get": a word for reading. ``` ## Deletes or cancels (2) Removes, cancels or revokes something. Claude Code: deny. ### `checkout` - The name "checkout" says "checkout": a word for a change. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Requires `checkout:write` or `checkout:link`, or no key: send `meta.ucp-agent.profile` for the same payment link. **Checkout is always human-in-the-loop: it returns a link the buyer opens and confirms — it never charges a card or completes an order on its own.** **Call `set_shipping_address` first unless `fulfillment` is `"external"` (the seller's site collects the address).** Cart total must not exceed the platform cap (`kifly://platform/limits`). **To pre-fill the buyer's email on the payment page, pass `email` — ask the buyer for it in plain language ('what email should the receipt go to?'). Never ask the buyer to paste a token.** Read `payment_rail` on the response BEFORE telling the buyer anything: `'stripe-checkout'` is paid through Kifly, `'directory-handoff'` hands the buyer to the seller's own site to pay, with a tracked link per product and no Kifly payment link, and `'shopify-native'` sends the buyer to the seller's own checkout. **Full response field reference, including every refusal code: read the `kifly://docs/checkout-response` resource.** ``` ### `update_cart_item` - The name "update_cart_item" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Requires `cart:write`, or no key: send `meta.ucp-agent.profile`. 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 `QUANTITY_EXCEEDS_LIMIT`. ``` ## Can't be undone (2) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `request_buyer_code` - The name "request_buyer_code" says "request": a word for a change. - The description's first verb is "send": a word for sending, and what is sent cannot be taken back. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text 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`. Always returns `{ sent: true }`, whether or not the email has a Kifly account. If the buyer never receives a code, they likely don't have an account yet: call `register_buyer` instead, which creates one and emails a code either way. Requires the `buyer:write` capability (marketplace/network keys). ``` ### `submit_feedback` - The name "submit_feedback" says "submit": a word for a change. - The description's first verb is "send": a word for sending, and what is sent cannot be taken back. - Tag outbound: The input takes a URL (input.contact.url): a request to a URL can carry data to whoever runs it. - Findings: info credentials-mention Description, as the server wrote it: ```untrusted-server-text Send structured feedback to the Kifly team. **No API key required** — send `meta.ucp-agent.profile` and this works with no credential at all. **Call after a confusing response, a dead-end, or a successful workaround you had to invent** — it's how we improve the agent surface, and a report from the moment you were stuck is worth more to us than a working purchase. 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 doing (tool called, query used, response shape, what you expected). Add `suggested_fix` only if you have a concrete idea. Rate-limited. ``` ## Changes things (9) Creates or changes something that can be changed back. Claude Code: ask. ### `add_to_cart` - The name "add_to_cart" says "add": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Requires `cart:write`, or no key: send `meta.ucp-agent.profile`. 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_EXCEEDS_LIMIT`; exceeding the cart total returns 400 `CART_TOTAL_EXCEEDS_LIMIT` at checkout. `cart.kifly_purchasable` (and `cart.fulfillment`) carries the same signal as create_cart's `seller` field. ``` ### `create_cart` - The name "create_cart" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text 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. The response's `seller.kifly_purchasable` (and `seller.fulfillment`) tells you upfront where the buyer pays — `false`/`"external"` means the buyer pays on the seller's own site: build the cart as usual; checkout hands them there with a link per product. Never say the order is placed. The same flag rides every add_to_cart/get_cart response. ``` ### `get_seller` - The name "get_seller" says "get": a word for reading. - The description's first verb is "call": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "call" and "website": it reads web pages, which anyone can write. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text **Call first when the user names a store or its website**: it says whether Kifly carries it before you open a browser. Returns the seller's public profile: location, storefront URL, delivery fee and coverage, catalog size, `verified_domains` (domains it proved it controls; trust signal, not identity), and `fulfillment` (buy here, or hand off to the seller's site). **Call before `create_cart` or `set_shipping_address` to check it ships to the buyer.** `cities` is never capped here. **`coverage_configured: false` = ships NOWHERE; an empty `states` is NOT nationwide. `merchant_managed: true` = shipping is set at the seller's own checkout; never report it as not shipping.** Details: `kifly://docs/delivery`. Name the seller by ONE of `handle`, `domain` (any URL works) or `name`. A miss is `SELLER_NOT_FOUND` with `details.did_you_mean`: ask the user, never pick. `SELLER_AMBIGUOUS` = several share that name; ask which. Seller-scoped tokens may omit all three. ``` ### `quick_buy` - Nothing in its name or description says what it does, so it is counted as a write. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Tag outbound: The input takes a destination (input.shipping_address.phone): what the tool writes goes there. Description, as the server wrote it: ```untrusted-server-text 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-step carts. **You must call `search_products` first** so Kifly knows each variant's seller (quick_buy returns 422 `VARIANT_SNAPSHOT_MISSING` otherwise). One cart = one seller: every item must belong to the same seller (409 `CART_SELLER_MISMATCH` otherwise) — for a network token, pass that seller's `seller_handle`. Returns `{ cart_id, items_added, seller, delivery }`. `delivery` is exactly what `set_shipping_address` returns — **quote `cart_total_with_delivery_cents` before sending the buyer to pay**; on `delivery_eligible: false` no address is saved, so you can call again with a covered address. Field detail and the three coverage cases: `kifly://docs/delivery`. **quick_buy never charges — it stops at the cart. The buyer still pays via `checkout`**, which returns the payment link they open themselves. On a 5xx/'temporarily unavailable' error, retry once with the same arguments. ``` ### `register_buyer` - The description's first verb is "start": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text 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 their inbox, then call `verify_buyer` with the same email + code to get a `buyer_token` (`kfb_live_...`). **Store that token and pass it to `checkout` on every future order** — it pre-fills the buyer's email on the secure Stripe payment link. Safe to call for a buyer you believe is new; if they already have an account, verify_buyer still recovers it. ``` ### `request_feature` - The name "request_feature" says "request": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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 buyer articulate a real problem: ask OPEN, non-leading questions ('what were you trying to do? what got in the way? how do you handle it today?') — never 'would feature X help?'. Pre-fill the fields from the conversation and ask only for the gaps; keep it short. Separate the `problem` (the pain) from any `proposed_solution` (the fix). Name and email are taken from the buyer profile automatically — do not ask for them. Returns 202: it's logged for review. **Do NOT promise the user anything will be built** — just confirm it was recorded. ``` ### `save_buyer_address` - The name "save_buyer_address" says "save": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Tag outbound: The input takes a destination (input.address.phone): what the tool writes goes there. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `set_shipping_address` - The name "set_shipping_address" says "set": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Tag outbound: The input takes a destination (input.shipping_address.phone): what the tool writes goes there. Description, as the server wrote it: ```untrusted-server-text Requires `cart:write`, or no key: send `meta.ucp-agent.profile`. Persist a shipping address on the cart and confirm the seller can deliver to it. **Call BEFORE `checkout`.** Returns `delivery_eligible`. When true it also returns `cart_total_with_delivery_cents` — quote that full price before sending the buyer to pay, unless `shipping_priced_at` is `merchant_checkout`: then fee and total are null because the seller's own checkout prices shipping; say so, never call shipping free. When false, no address is saved and `delivery_coverage` says where the seller does cover, so you can retry with a covered address. Coverage semantics: `kifly://docs/delivery`. ``` ### `verify_buyer` - The input takes a statement or command to run (input.code), which can change anything it can reach. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text 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 `request_buyer_code` again). Requires the `buyer:write` capability. ``` ## Only reads (9) Looks things up and changes nothing. Claude Code: allow. ### `get_buyer_profile` - The name "get_buyer_profile" says "get": a word for reading. - Tag private-data: The description's first sentence says "retrieve" and "email": it reads mail. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "retrieve" and "email": it reads inbound email, which other people can write. Description, as the server wrote it: ```untrusted-server-text Retrieve a repeat buyer's saved name, email, and default shipping address, given their `buyer_token`. Use them to auto-fill `set_shipping_address`, and pass the token to `checkout` so Stripe pre-fills their email. `default_shipping_address` may be null — then collect it normally and call `save_buyer_address` so it is pre-filled next time. **Ask in plain language ('are you a returning Kifly shopper? what email is on your account?') — never ask a buyer to paste a token.** **How to get the token: read `kifly://docs/buyer-identity`** — the email-code sequence, the one-click sign-in alternative, and what to do for a new buyer. ``` ### `get_cart` - The name "get_cart" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text 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 hands the buyer to the seller's own site to pay: say so, so the buyer knows where they will pay. ``` ### `get_help` - The name "get_help" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get unstuck. Returns Kifly's website and support email for the BUYER, plus how to report the problem to Kifly's engineers yourself. Call this if you are stuck, hit an unresolvable error, or the buyer asks how to reach a human. Share the website and email with the buyer; use `submit_feedback` (no API key needed) to tell us what blocked you — that is the fastest way to get it fixed. ``` ### `get_platform_limits` - The name "get_platform_limits" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. Always read them at runtime rather than hardcoding. ``` ### `get_policies` - The name "get_policies" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text The seller's published returns, shipping and warranty policy, in their own words. **Call before telling a buyer what happens after purchase** — if it is not here, say so; never infer a typical policy. `available: false` is the normal case for most sellers and is not an error. `get_seller`'s `policies.available` tells you whether this call is worth making. Network tokens pass `handle`; seller-scoped tokens may omit it. ``` ### `list_orders` - The name "list_orders" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text 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` (`paid` | `shipped` | `delivered`), `items`, `amount_cents`, `placed_at`, and — once shipped — `tracking_number`, `carrier`, and a public `tracking_url`. **Pass `since` (an ISO-8601 timestamp from a previous check) to get only orders that changed since then** — surface those proactively ('your last order just shipped'). `order_id` identifies the order; `session_id` cross-references `order_status` for a single live checkout. ``` ### `list_sellers` - The name "list_sellers" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text 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 list. Use this to discover which sellers are available and which ship to a buyer's location before calling `get_seller` or `search_products`. **Pagination:** when `kifly:hasMore` is true, pass `kifly:nextCursor` as `cursor` to fetch the next page. Default page size is 20, max 50. ``` ### `order_status` - The name "order_status" says "status": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text No key needed for your own session: send the profile you checked out with. 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. ``` ### `search_products` - The name "search_products" says "search": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "browse": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text Search or browse Kifly's product catalog across every seller on the network. Multilingual semantic search (100+ languages); omit `q` to browse recent listings. Pass `q` as an array (up to 5) to try several phrasings in ONE call instead of N searches. Too many hits? Ask once with `facets: true`, then narrow with `delivers_to`, price, `category` or `seller_handle`; page with `cursor` when `kifly:hasMore`. Returns a JSON-LD ItemList. **Rules that matter before you read the response:** - Cart every product the buyer wants: checkout hands them to pay with the cart ready. `kifly:purchasable: false` is still buyable, paid on the seller's own site. `availability` is STOCK; `kifly:purchasable` is WHERE they pay. - On `availability:OutOfStock`, still show it if asked, say it is sold out, and never cart it (`add_to_cart` returns 409). - When a product has several size/style variants, ask the buyer ONE option axis at a time (`kifly:productOptions` gives the axes in the seller's order). Never recite the combination matrix. - On an empty result, read `kifly:emptyReason`: say nothing matched rather than guessing, then offer `kifly:suggestions` (related, NOT matches). Items with `kifly:offNetwork` are outside retailers': relay `kifly:affiliateDisclosure`, cart as usual. **Full field reference: resource `kifly://docs/search-response`** (seller map, delivery coverage, variants, capped fields, every `kifly:` extension). Fetch it once for field-level detail. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `kifly`: ```json { "permissions": { "allow": [ "mcp__kifly__search_products", "mcp__kifly__get_cart", "mcp__kifly__get_buyer_profile", "mcp__kifly__list_orders", "mcp__kifly__get_policies", "mcp__kifly__list_sellers", "mcp__kifly__get_platform_limits", "mcp__kifly__order_status", "mcp__kifly__get_help" ], "ask": [ "mcp__kifly__create_cart", "mcp__kifly__add_to_cart", "mcp__kifly__set_shipping_address", "mcp__kifly__quick_buy", "mcp__kifly__register_buyer", "mcp__kifly__request_buyer_code", "mcp__kifly__verify_buyer", "mcp__kifly__save_buyer_address", "mcp__kifly__submit_feedback", "mcp__kifly__request_feature", "mcp__kifly__get_seller" ], "deny": [ "mcp__kifly__update_cart_item", "mcp__kifly__checkout" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__kifly__search_products`: untrusted-input - `mcp__kifly__create_cart`: untrusted-input - `mcp__kifly__add_to_cart`: untrusted-input - `mcp__kifly__get_cart`: untrusted-input - `mcp__kifly__update_cart_item`: untrusted-input - `mcp__kifly__set_shipping_address`: untrusted-input, outbound - `mcp__kifly__quick_buy`: untrusted-input, outbound - `mcp__kifly__checkout`: untrusted-input - `mcp__kifly__register_buyer`: untrusted-input - `mcp__kifly__request_buyer_code`: untrusted-input - `mcp__kifly__verify_buyer`: untrusted-input - `mcp__kifly__get_buyer_profile`: private-data, untrusted-input - `mcp__kifly__list_orders`: untrusted-input - `mcp__kifly__save_buyer_address`: untrusted-input, outbound - `mcp__kifly__submit_feedback`: outbound - `mcp__kifly__get_seller`: untrusted-input - `mcp__kifly__get_policies`: untrusted-input - `mcp__kifly__list_sellers`: untrusted-input - `mcp__kifly__order_status`: untrusted-input ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T15:08:18.837Z, unchanged since 2026-10-22T15:08:18.837Z.
