## Exfil surface

132 private-data -> untrusted-input -> outbound paths in this server alone. Denying 2 private-data tools breaks every one: `mcp__photoprintagent__list_agent_keys`, `mcp__photoprintagent__preview_print_item`.

| Tag | Meaning | Tools |

## Deletes or cancels (4)

Removes, cancels or revokes something. Claude Code: deny.

### `confirm_complimentary_order`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Explicitly approve fulfillment of your existing zero-total order after a coupon change. Requires buyerApproved:true and the current pricingVersion. Original order terms consent remains required. Idempotent for an already confirmed complimentary order; never use this for a positive total.
```

### `delete_photo`

- The name "delete_photo" says "delete": a word for removing or ending something.
- The description says "Permanently delete".
- The server marks it destructive (destructiveHint: true).
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Permanently delete one of your uploaded photos. Photos locked or reserved by an order cannot be deleted.
```

### `pay_print_order`

- The name "pay_print_order" says "pay": a word that usually means money moves, which cannot be taken back.
- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Request an x402 v2 challenge without a signature, or settle an approved signature and submit the paid print. Uses the same guarded payment flow as REST. An unsigned call returns payment_required in structuredContent (MCP HTTP 200). Never repay an ambiguous order.
```

### `revoke_agent_key`

- The name "revoke_agent_key" says "revoke": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Revoke one of your account keys by ID. Requires a verified Firebase account session; guest and agent keys cannot manage keys.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `quote_crypto_payment`

- The name "quote_crypto_payment" says "payment": a word that usually means money moves, which cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Lock an unpaid order in a listed token for up to 60 seconds. Obtain approval of this exact amount and include cryptoQuoteId in the payment retry.
```

## Changes things (14)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_agent_key`

- The name "create_agent_key" 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
Mint a 90-day account key using a verified Firebase ID token in Authorization. Guests and existing agent keys cannot mint keys.
```

### `create_print_order`

- The name "create_print_order" 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Create one order from the approved quote, which already contains buyer contact and address. Requires termsAccepted:true confirming acceptance of https://photoprintagent.com/terms with the buyer’s authorization, separately from buyerApproved:true. Never infer acceptance from an upload, quote, or previous order. Reuse the same idempotency key for retries. Returns a buyer card checkout URL or x402 payment URL; call pay_print_order for the challenge. A zero-total coupon order is submitted with buyerApproved:true and needs no card or wallet. Optional couponCode must match the approved quote.
```

### `create_upload`

- The name "create_upload" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Get the authenticated binary upload endpoint and product/crop headers. Pass productId from list_products for every image. Upload each required image separately; retain the returned IDs in slot order. Crops and resolution checks use that product’s artwork specifications, not a universal 4x6 size. POST the image bytes separately; never put base64 or remote image URLs in MCP. For recoverable uploads, send a stable Idempotency-Key on POST and check GET /api/uploads/{key} after a lost response. Retry the same bytes and options with the same key; never retry payment as an upload recovery step. SDK: https://photoprintagent.com/sdk/photo-upload.mjs. No storage is allocated until upload. JPEG, PNG/APNG, WebP, GIF, HEIC/HEIF, TIFF, AVIF, BMP and self-contained SVG are supported. Read acceptedMimeTypes, acceptedExtensions and imageHandling for frame/page selection, transparency, and limits. Use application/octet-stream when MIME type is unavailable. Unsupported encodings must be converted before upload.
```

### `estimate_print_price`

- 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.
- 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
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.
```

### `get_checkout_link`

- The name "get_checkout_link" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Mint a private on-site checkout link for your existing order. Preserve its access fragment, share only with the buyer, and never create another order to recover a checkout. Card payment uses the embedded payment modal; MCP never accepts card details.
```

### `get_order`

- The name "get_order" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info credentials-mention, info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read your private order. Payment and fulfillment states are separate; processing means PhotoPrintAgent accepted the order for processing, not shipped. Use only PhotoPrintAgent branding and the returned customer status in updates. Does not initiate charges. Polling verifies a completed card checkout only with payment permission or a full guest/account credential. Read-only OAuth returns saved status without reconciliation.
```

### `preview_print_price`

- The name "preview_print_price" says "preview": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- 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.phone): what the tool writes goes there.
- Findings: info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `quote_prints`

- 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.phone): what the tool writes goes there.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
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:

```untrusted-server-text
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.
