Use create_order only if you hold a Be..." ``` ## Deletes or cancels (2) Removes, cancels or revokes something. Claude Code: deny. ### `cancel_cart` - The name "cancel_cart" says "cancel": a word for removing or ending something. - The description says "Permanently delete". Description, as the server wrote it: ```untrusted-server-text Permanently delete a cart by cart_id. Use when the customer abandons the session or wants to start over. Has no effect on any checkout or paid order already created from this cart. Irreversible, create a new cart to restart. ``` ### `cancel_checkout` - The name "cancel_checkout" says "cancel": a word for removing or ending something. Description, as the server wrote it: ```untrusted-server-text Abort an unpaid checkout and release its checkout_id.

To restart, create a new cart and checkout from scratch. ``` ## Changes things (12) Creates or changes something that can be changed back. Claude Code: ask. ### `check_colour_stock` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Verify whether a specific colour is available before configure_product. Returns in_stock boolean, expected_restock_date if out of stock, and up to 5 alternative in-stock colours ordered by similarity.

Description, as the server wrote it: ```untrusted-server-text Generate a Yoco card or Ozow instant-EFT payment link; this does NOT complete payment. Rejects cancelled checkouts and rechecks stock and totals first. An atomic claim prevents competing gateway calls. Returns payment_url or null plus status and message; cloud callers may be held. Retain a successful URL: repeat calls return payment_pending with no URL. Gateway failures raise an error, send no payment-link email and require team review rather than an automatic retry. Poll get_order with customer_email for payment status. ``` ### `configure_product` - The description's first verb is "lock": a word for a change. Description, as the server wrote it: ```untrusted-server-text Lock in a full blind specification: product, dimensions, colour, and mount type (inside recess or outside face-fix). Validates that the colour exists and is in stock, then prices the blind. Returns a configuration summary to pass directly into create_cart. Call check_colour_stock first if availability is uncertain. ``` ### `create_cart` - The name "create_cart" says "create": a word for a change. - Tag outbound: The input takes a destination (input.customer.phone): what the tool writes goes there.

Description, as the server wrote it: ```untrusted-server-text Phase 1 of 2 in the purchase flow. Convert a cart (or inline items + customer) into a checkout. Customer name, email, and phone are required. Returns checkout_id. No payment link is minted yet, call complete_checkout for that. Use update_checkout to correct customer details before finalising. ``` ### `create_order` - The name "create_order" says "create": a word for a change. - Findings: info credentials-mention Description, as the server wrote it: ```untrusted-server-text Legacy auth-required tool, prefer the open UCP flow (create_cart → create_checkout → complete_checkout) which needs no credentials. Use create_order only if you hold a Bearer token and want a single-call path to a payment link. All item prices are re-verified server-side against the live pricing engine, agent-supplied prices are ignored. Returns a Yoco or Ozow payment_url. ``` ### `get_whatsapp_handoff` - The name "get_whatsapp_handoff" says "get": a word for reading. - The description's first verb is "generate": a word for a change. - Tag private-data: The description's first sentence says "contact": it reads contacts.

Description, as the server wrote it: ```untrusted-server-text Submit a price match claim when the customer has found the same blind at a lower price elsewhere.

Not applicable to: Blinds Direct (same supplier), clearance or flash-sale prices, or out-of-stock items. Requires product_id and competitor_price_zar at minimum. ``` ### `request_swatch` - The name "request_swatch" says "request": a word for a change. Description, as the server wrote it: ```untrusted-server-text Log up to 5 colour codes against an EXISTING order for the team (order_ref required; without it the tool returns status order_required and logs nothing). Custom Blinds does not post individual swatches or off-cuts. For orders over R8,000 the customer can ask for the full sample book via WhatsApp; if nothing suits, full refund with no fees. Never quote a sample-book price or courier cost. ``` ### `submit_enquiry` - The name "submit_enquiry" says "submit": a word for a change. Description, as the server wrote it: ```untrusted-server-text Legacy auth-required tool, prefer the open UCP flow (create_cart → create_checkout → complete_checkout) for credentialless checkout.

Description, as the server wrote it: ```untrusted-server-text Returns the link to the Custom Blinds measuring guide when a customer is unsure how to measure. There is no AR tool: the guide shows how to measure for an inside (recess) or outside (face fix) fit in two minutes, and a customer who is still unsure can order with best guess sizes, receive a free tape measure and confirm before production starts. ``` ### `get_cart` - The name "get_cart" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Retrieve live cart state by cart_id: full item list, calculated totals in ZAR, and any customer details stored so far.

Call this when a customer asks 'when will it arrive?' to give an honest production timeline. ``` ### `get_order` - The name "get_order" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Retrieve a confirmed order's status, items, and payment details by order_id. customer_email is required as soft-auth and must exactly match the order record, prevents arbitrary order lookups.

Description, as the server wrote it: ```untrusted-server-text Get an exact ZAR price using product_id from search_catalog or lookup_catalog, width_mm and height_mm. Prices include VAT and delivery.

Description, as the server wrote it: ```untrusted-server-text Translate a customer's primary concern into a product recommendation. primary_concern must be one of: blockout, heat, glare, moisture, privacy, security, automation.

Security concern routes to brochure MCP (Garden Route customers only). ``` ### `lookup_catalog` - The name "lookup_catalog" says "lookup": a word for reading. Description, as the server wrote it: ```untrusted-server-text Preferred structured discovery. Filter by category, partial colour name or required supported width/drop in mm.

Pass that id as product_id to get_price or configure_product. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `cb-shop`: ```json { "permissions": { "allow": [ "mcp__cb-shop__search_products", "mcp__cb-shop__get_price", "mcp__cb-shop__search_catalog", "mcp__cb-shop__lookup_catalog", "mcp__cb-shop__get_product", "mcp__cb-shop__get_cart", "mcp__cb-shop__get_checkout", "mcp__cb-shop__get_order", "mcp__cb-shop__get_payment_methods", "mcp__cb-shop__get_product_recommendation", "mcp__cb-shop__get_ar_visualizer_url", "mcp__cb-shop__get_delivery_estimate" ], "ask": [ "mcp__cb-shop__configure_product", "mcp__cb-shop__submit_enquiry", "mcp__cb-shop__create_order", "mcp__cb-shop__create_cart", "mcp__cb-shop__update_cart", "mcp__cb-shop__create_checkout", "mcp__cb-shop__update_checkout", "mcp__cb-shop__complete_checkout", "mcp__cb-shop__check_colour_stock", "mcp__cb-shop__request_swatch", "mcp__cb-shop__get_whatsapp_handoff", "mcp__cb-shop__request_price_match" ], "deny": [ "mcp__cb-shop__cancel_cart", "mcp__cb-shop__cancel_checkout" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__cb-shop__create_cart`: outbound - `mcp__cb-shop__update_cart`: outbound - `mcp__cb-shop__create_checkout`: outbound - `mcp__cb-shop__update_checkout`: outbound - `mcp__cb-shop__get_whatsapp_handoff`: private-data - `mcp__cb-shop__get_ar_visualizer_url`: untrusted-input ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T14:51:20.103Z, unchanged since 2026-10-22T14:51:20.103Z.
