## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `check_print_file`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Check whether artwork will print correctly at the given size.

Give the artwork as file_url (public https link) or file_base64. `size` is required
for images. Returns the verdict, what is wrong, whether repair reaches a printable
file, and the prompt to regenerate with when it cannot.

```

### `fix_print_file`

- 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
Repair what can be repaired and return download links for the print-ready file.

Rebuilds QR codes so they scan, fixes proportions by adding paper rather than
cropping, and returns a PDF the size of the paper (inside a border a home printer can
reach, where the paper is one a home printer takes) plus a PNG and, where it differs,
an edge-to-edge PDF for print shops. For small pieces such as business cards and
invitations it also returns letter and A4 sheets with several copies and cut marks.
Links last 30 minutes. Resolution is never faked:
when that is the problem the result carries the prompt to regenerate with.

`qr_url` is the link a QR code should carry when the one on the artwork was drawn by
an image model and decodes to nothing.

```

### `plan_artwork`

- 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.

Description, as the server wrote it:

```untrusted-server-text
What to ask an image model for, before generating artwork for this print size.

Returns the pixel dimensions to generate at, the floor below which it will look soft,
the proportions, the smallest QR code that scans from where this piece is read, and a
line to paste into the image prompt.

```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `list_print_sizes`

- The name "list_print_sizes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The named print sizes `size` accepts, with their dimensions.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `printsanity`:

```json
{
  "permissions": {
    "allow": [
      "mcp__printsanity__list_print_sizes"
    ],
    "ask": [
      "mcp__printsanity__plan_artwork",
      "mcp__printsanity__check_print_file",
      "mcp__printsanity__fix_print_file"
    ],
    "deny": []
  }
}
