Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it
Estimate configured product and shipping charges using only product, quantity, ZIP and state. No photos or contact details required. Unknown tax or charges remain null; this is not a payable quote.

  What this check looks for
Description, as the server wrote it
Estimate product and destination pricing before using the customer’s photos for an order. Uses placeholder artwork and does not create an order or a payable quote. Call quote_prints with buyer consent before checkout.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a destination (input.shipping.phone): what the tool writes goes there.
Description, as the server wrote it
Quote private uploaded photo IDs and a US destination for an optional productId from list_products (defaults to photo-4x6). Items may specify productId to mix products using the same print service; omitted item productId uses the order productId. For a single image use items:[{photoId,productId,quantity}]. For a multi-image design use items:[{photoIds:[frontId,backId,...],quantity}]; array order is print order and quantity counts complete products, not individual images. Follow artwork.minImages/maxImages and labels. For artwork.calendar, upload a cover plus one photo per month and include calendar:{startYear,startMonth} on the item; the server generates and interleaves the date grids. Do not upload date grids. For artwork.composition, upload each source photo at the per-image dimensions; the server assembles the ordered photos into the single print file shown by the layout. Never precompose those photos or send each side as a separate item. Up to 200 uploaded images and 500 product units per order. Shipping follows the product’s configured pricing; flat rates can differ for 1 versus 2+ prints. Use the returned shipping and total; never multiply flat shipping by quantity. Requires consent for PhotoPrintAgent to process these photos and address for printing and delivery. Unique photos, at most 500 total prints. Optional couponCode is validated here; price.total is the discounted buyer amount and price.discount is the savings in USD cents.

Description, as the server wrote it

- The name "list_orders" says "list": a word for reading.
Description, as the server wrote it
List your most recent orders, newest first, up to 50. Does not reconcile payments; use get_order for a specific order. Unpaid Admin Only orders require a verified admin session.

Why it is in this group
- The name "list_products" says "list": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it
Public paginated product catalog, print specifications, and availability. Follow nextOffset until null. availableOnly defaults to true; false includes unavailable public products with explicit available flags. Filters cover query, category, finish, dimensions and known unit price range. capabilities distinguishes API support from current orderability. productCode and sku are PhotoPrintAgent seller codes for customer listings and search; id remains the API identifier for uploads and quotes. Each product supplies artwork dimensions, minimum/maximum image counts, ordered slot labels, bleed and rotation rules. These apply to all active supported products, including multi-image designs. Artwork minimumDpi values are print quality guidance, not an upload rejection threshold: accept smaller valid images, resize them, and treat reduced quality as a nonblocking warning. Admin Only products are never listed. Pass a returned products[].id as productId when uploading and quoting; omission selects the original photo-4x6 product. Price depends on the items and destination; call quote_prints for an authoritative total.

preview_print_itemPreview one complete design using owned uploaded photoIds in product slot order.Reads private dataNo findings
Why it is in this group
- The name "preview_print_item" says "preview": a word for reading.
What it can reach
- private-dataThe input names a calendar (input.calendar), and the tool reads: it reads calendars.
Description, as the server wrote it
Preview one complete design using owned uploaded photoIds in product slot order. Reviewed compositions (including photobooth strips) render the same assembly used for fulfillment. For artwork.calendar, include calendar:{startYear,startMonth}; previews include the generated date grids in print page order. Other products return ordered flat artwork pages, not a physical mockup. JPEG thumbnails appear as MCP image content after the JSON metadata. Page with offset/limit; no order or external photo link is created.

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.

12 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.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as narrow. Review it before you use it.
