Claude Code: deny. ### `cancel_booking` - The name "cancel_booking" says "cancel": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text DEPRECATED — this tool is now called cancel_order and behaves identically. The old name keeps working so that agents connected before the rename are not broken. Prefer cancel_order, which is accurate for certificates as well as appointments. Cancel a booking and refund it in full. Requires the email the order was created with. Confirm with the buyer before calling — this releases the slot and reverses the payment. If this tool ever fails, tell the buyer they can cancel by emailing the seller with their order number instead; the seller honours that on identical terms. ``` ### `cancel_order` - The name "cancel_order" says "cancel": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Cancel a booking and refund it in full. Requires the email the order was created with. Confirm with the buyer before calling — this releases the slot and reverses the payment. If this tool ever fails, tell the buyer they can cancel by emailing the seller with their order number instead; the seller honours that on identical terms. ``` ### `renounce_certificate` - The description's first verb is "destroy": a word for removing or ending something. - The description says "cannot be undone". - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Destroy the proof of ownership for an AI Repellent, completing the transfer. After Yves Klein, who required buyers of his immaterial works to burn the receipt: keeping it meant owning a receipt, burning it meant owning the work with nothing left to demonstrate it. This strikes the hash from the register permanently and cannot be undone. Explain that to the buyer and get their agreement before calling it — some will want the certificate precisely because it is a certificate. Note that this needs only the order number, which is printed on the certificate: it is a bearer instrument, so anyone holding the PDF can do this. Say so if the buyer is planning to share it. ``` ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `transfer_certificate` - The name "transfer_certificate" says "transfer": a word for a change that another call does not undo. Description, as the server wrote it: ```untrusted-server-text Pass a certificate to someone else. Klein's receipts carried a clause — a transferable zone may be ceded by its owner only at double its initial purchase value — so a transfer here costs exactly twice what the certificate cost, and the shop will not do it for less. The serial number and the hash do not change: it is the same object endorsed to a new bearer, not a new certificate. Returns a payment link; the transfer takes effect once it is paid. ``` ## Changes things (6) Creates or changes something that can be changed back. Claude Code: ask. ### `create_order` - The name "create_order" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Reserve a slot and get a payment link. This is the only way to buy — there is no checkout on the website. The slot is held for 30 minutes. Confirm the exact time and the price with the buyer before calling this, and use their real email address: the calendar invitation and receipt go there. You must call list_products first, put the session options to the buyer in your own reply, and wait for them to choose. This tool needs the catalogue_token from that call and buyer_confirmed_session: true, which you may only set once the buyer has actually answered. Choosing a session on their behalf from what they said earlier is not the same as asking, and is not acceptable here. Before calling, ask the buyer what they want to discuss and what they are hoping to get out of the call, and pass their answers as topic and desired_outcome. Fifteen minutes is short; the seller uses these to prepare, and a booking that arrives blank wastes some of the time the buyer paid for. ``` ### `order_certificate` - 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 Buy a certificate. Certificates are objects, not appointments: there is no slot, no calendar entry and no meeting. One is issued the moment payment settles, emailed as a PDF, and registered against a hash anyone can verify. Use this instead of create_order, which is only for booking time. As with sessions, show the buyer what is on offer and let them choose rather than deciding for them. ``` ### `reschedule_booking` - The name "reschedule_booking" says "reschedule": a word for a change. Description, as the server wrote it: ```untrusted-server-text DEPRECATED — this tool is now called reschedule_session and behaves identically. The old name keeps working so that agents connected before the rename are not broken. Prefer reschedule_session, which is accurate for certificates as well as appointments. Move a booking to a different slot at no charge. Requires the email the order was created with. Call check_availability first to get a valid new_slot_id. ``` ### `reschedule_session` - The name "reschedule_session" says "reschedule": a word for a change. Description, as the server wrote it: ```untrusted-server-text Move a booking to a different slot at no charge. Requires the email the order was created with. Call check_availability first to get a valid new_slot_id. ``` ### `update_booking` - The name "update_booking" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text DEPRECATED — this tool is now called update_order_details and behaves identically. The old name keeps working so that agents connected before the rename are not broken. Prefer update_order_details, which is accurate for certificates as well as appointments. Change the session type or the brief on an existing booking — what the buyer wants to discuss, what they want out of it, or the background they want read first. Use this when the buyer refines their thinking after booking, which is common: people work out the real question after the date is in the diary. Only the fields you pass are changed. This does not move the meeting — use reschedule_booking for that. ``` ### `update_order_details` - The name "update_order_details" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Change the session type or the brief on an existing booking — what the buyer wants to discuss, what they want out of it, or the background they want read first. Use this when the buyer refines their thinking after booking, which is common: people work out the real question after the date is in the diary. Only the fields you pass are changed. This does not move the meeting — use reschedule_booking for that. ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `check_availability` - The description's first verb is "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List bookable slots. Optionally narrow with an ISO date or datetime range, and pass the buyer's IANA timezone to get their local times alongside the seller's. ``` ### `get_booking` - The name "get_booking" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text DEPRECATED — this tool is now called get_order_details and behaves identically. The old name keeps working so that agents connected before the rename are not broken. Prefer get_order_details, which is accurate for certificates as well as appointments. The Teams joining link and meeting details for a paid order. Available only once payment has settled. ``` ### `get_order_details` - The name "get_order_details" says "get": a word for reading. - Tag private-data: The description's first sentence says "meeting": it reads calendars. Description, as the server wrote it: ```untrusted-server-text The Teams joining link and meeting details for a paid order. Available only once payment has settled. ``` ### `get_order_status` - The name "get_order_status" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Whether an order has been paid. After the first call this BLOCKS, waiting for the buyer to finish paying, and returns the instant it settles — so call it once rather than polling in a loop. It holds for up to five minutes, longer than a person normally takes to pay; if it returns still 'pending_payment', call it again. IMPORTANT: you cannot send the buyer a message while this call is waiting. Make sure you have already given them the payment link before you let it block, or they will be left watching you do nothing. ``` ### `get_shop_info` - The name "get_shop_info" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text What this shop sells, the price, and how buying works. Call this first if you have not dealt with this shop before. ``` ### `list_products` - The name "list_products" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The session types this shop sells. Show these to the buyer and let them choose — do not pick for them unless they ask you to. Each returns an id to pass to create_order as session_type. If the buyer is unsure, the good_for examples are there to help them decide, and 'general' is a perfectly good answer. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `shop`: ```json { "permissions": { "allow": [ "mcp__shop__get_shop_info", "mcp__shop__list_products", "mcp__shop__check_availability", "mcp__shop__get_order_status", "mcp__shop__get_order_details", "mcp__shop__get_booking" ], "ask": [ "mcp__shop__create_order", "mcp__shop__order_certificate", "mcp__shop__transfer_certificate", "mcp__shop__update_order_details", "mcp__shop__update_booking", "mcp__shop__reschedule_session", "mcp__shop__reschedule_booking" ], "deny": [ "mcp__shop__cancel_order", "mcp__shop__cancel_booking", "mcp__shop__renounce_certificate" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__shop__get_order_details`: private-data ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T15:10:25.137Z, unchanged since 2026-10-22T15:10:25.137Z.
