    Description, as the server wrote it
    Publish a PUBLIC post to the Swop feed as the linked account's SmartSite: a caption plus up to 4 images. Each image may be an https URL, a data:image/...;base64 URI, or bare base64 (PNG/JPEG/GIF/WebP, max 5 MB; keep inline images under ~3 MB total so the request fits). TWO-STEP like swop_send: call WITHOUT confirm to get a preview — Swop hosts the images and returns who it posts as, the exact caption, the hosted image URLs and a previewId. Show the user that exact caption and every image and get an explicit yes. Then call again with the SAME caption and smartsiteId, the `images` array exactly as the preview returned it, the previewId, and confirm: true. Any change after the preview is refused — preview again. Each preview publishes at most once: re-confirming it returns the same post (duplicate: true). Never confirm before the user has seen the preview.

  • swop_create_checkoutTake payment on the seller's own website: creates a checkout for a cart of the linked account's OWN products, so a buyer pays there instead of being sent to Swop.No findings

    Why it is in this group

    • The name "swop_create_checkout" says "create": a word for a change.
    Description, as the server wrote it
    Take payment on the seller's own website: creates a checkout for a cart of the linked account's OWN products, so a buyer pays there instead of being sent to Swop. For a single shareable link use swop_get_product_link instead. Prices come from the seller's catalogue and must NOT be sent — a price in the request is rejected. Shipping is charged automatically for physical products, and for those the buyer's name, email and delivery address are REQUIRED (the call is refused otherwise, naming what is missing). Rails: USDC on Solana always; set offerCard when the seller is card-enabled and every item is a physical good — then the response has cardOffered: true and paymentRequest is null until the buyer picks a rail on the seller's page via the public URLs POST /api/v5/checkout-intents/{intentId}/card-payment-intents (Stripe client secret for a Payment Element) or POST .../select-crypto (publishes the Solana Pay request). Otherwise paymentRequest is returned at once (a solana: URL the buyer's wallet opens, also fine as a QR code). Settlement is automatic once the payment lands — nothing to confirm; poll swop_get_checkout for status. Show the buyer the products, quantities and total before creating.

To change an existing product use swop_update_product instead. name, description and image are all REQUIRED by the backend. Confirm name and price with the user before creating.

    Description, as the server wrote it
    Show an existing product on the linked account's SmartSite as a tile visitors can buy from. Pass the templateId returned by swop_create_product (or the id from swop_list_my_products). Each call ADDS a new tile and never replaces existing ones, so check swop_get_my_smartsite first to avoid duplicates; remove a tile with swop_remove_link. The product must belong to the linked account.

    Description, as the server wrote it
    Allow ONE website to display the linked account's Swop checkout inside a frame. This is a security setting: only registered origins can ever frame the checkout, so a leaked API key still cannot put it on someone else's site.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

44 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 private-data tool breaks every one.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write11
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
