- **Endpoint Security**: 80/100
  - 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 82/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2230 tokens (~159/item across 14 items; 13 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 80/100
  - Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% 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 13 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `get_print_quote` (~240 tokens)

Get a 3D print quote

Use this when someone asks how much it costs to 3D print a part, or wants a quote to have a 3D model (an STL, 3MF, STEP or OBJ file) printed and shipped by 3D Printer on Demand. It reads the attached file, checks that it can be printed, saves the quote, and returns the estimate with a private link that opens the saved quote on our website. When no file is attached, or the file type cannot be read, it returns a link to upload the file on our website. It does not cover drawings or photos.

Input parameters:

- `color` (string): Color name for the chosen material. Default is the material's first color.

Check a 3D model for printing

Use this when someone attaches an STL, 3MF, STEP or OBJ file and wants to know whether it will 3D print well: size, walls, mesh problems and what to change. It reads the file, runs the same automatic design checks as our website, and stores nothing. It gives no quote. When no file is attached, it returns a link to upload the file on our website.

It returns published starting clearances and hole guidance, each with its source, and how to test the fit. It gives no single universal hole offset, because none is published.

Input parameters:

- `fit_type` (string): What the fit is for: sliding-moving, bolt-clearance, pin-in-hole, mating-fdm-parts, press-interference or snap-fit.
- `hole_axis` (string): vertical-z when the hole goes through a top or bottom face, horizontal-xy when it goes through a side wall.

### Is the 3D Printer on Demand MCP server still maintained?

3D Printer on Demand is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
