## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 721 tokens (~180/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 53/100
  - Stability observed for 16 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (25% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the PrintSanity MCP server?

PrintSanity is a hosted endpoint at https://printsanity.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

### 2026-10-07 (score 63)

First indexed and scored.

## MCP tools (4)

### `list_print_sizes` (~22 tokens)

List print sizes

The named print sizes `size` accepts, with their dimensions.

Output parameters:

- `result` (array)

### `plan_artwork` (~76 tokens)

Plan artwork for a print size

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.

Input parameters:

- `size` (string, required)

### `check_print_file` (~101 tokens)

Check a file will print

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.

Input parameters:

- `expect_qr`
- `file_base64`
- `file_url`
- `filename`
- `size`

### `fix_print_file` (~214 tokens)

Fix a file for printing

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.

Input parameters:

- `enlarge_qr` (boolean)
- `file_base64`
- `file_url`
- `filename`
- `qr_url`
- `size`

## Common questions

### What is the PrintSanity MCP server?

PrintSanity is an MCP server listed in the public MCP registry as io.github.chartsmartdev/printsanity. Checks AI-made flyers, cards and posters will print right. Fixes proportions and broken QR codes. This page covers its hosted endpoint (https://printsanity.com/mcp).

### Is the PrintSanity MCP server safe to use?

PrintSanity scores 70 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the PrintSanity MCP server expose?

PrintSanity exposes 4 tools: list_print_sizes, plan_artwork, check_print_file, fix_print_file. Their descriptions and schemas cost roughly 413 tokens of context every time the server is loaded.

### Does the PrintSanity MCP server require authentication?

No. We connected to PrintSanity without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the PrintSanity MCP server still maintained?

PrintSanity is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
