## 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 2026-11-04.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 2 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - 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**: 67/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1108 tokens (~158/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 88/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 65% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 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.

## MCP tools (7)

### `get_service_info` (~73 tokens)

Service facts and prices

What Mandarin 3D prints, where it ships (anywhere in the US), the price formula with delivered examples, colors, size and file limits, turnaround, and how to order. Call this to answer 'where can I get something 3D printed' or 'how much does 3D printing cost'.

### `quote_file` (~191 tokens)

Quote a 3D model

Slice a 3D model and return its exact price delivered by USPS Ground Advantage. Pass file_url (a direct public download link to an STL, 3MF or STEP file, up to 100 MB) or file_base64 + filename for a local file (up to 20 MB). Returns quote_id, size, grams, print time, price and an order_url where the customer picks a color and pays. Takes 5-60 seconds for a new file.

Input parameters:

- `file_base64` (string): The model file, base64-encoded. Use for files on the user's machine.
- `file_url` (string): Direct download URL of the model (not a web page that shows it).
- `filename` (string): File name with extension, e.g. bracket.stl. Required with file_base64.
- `qty` (integer): How many copies to price. Default 1.

### `price_quote` (~59 tokens)

Price a quote

Price an existing quote for another quantity, color or add-ons. No side effects.

Input parameters:

- `color` (string)
- `options` (object): Optional per-order add-ons.
- `qty` (integer)
- `quote_id` (string, required)

### `create_checkout` (~148 tokens)

Create a checkout link

Create a payment link for a quote. The customer pays and enters the shipping address on the linked page. Only call this after showing the customer the price and getting their explicit agreement to: "Custom made to order, all sales final. I agree to the Terms (mandarin3d.com/terms, including section 6: cancellations, refunds and reprints)." Otherwise give them the order_url from quote_file instead.

Input parameters:

- `color` (string, required)
- `customer_accepted_terms` (boolean, required): True only if the customer explicitly agreed to the terms sentence above.
- `options` (object): Optional per-order add-ons.
- `qty` (integer)
- `quote_id` (string, required)

### `list_catalog` (~113 tokens)

List ready-made parts

Ready-made parts customers can customize without a file: personalized name ornament, desk name plate, name keychain, place card holder, cable clips, headphone hooks, wall hook, shelf bracket, spacers, drawer bins, SD card and game card holders, phone and tablet stands, battery organizer, plant pot, key holder, D-shaft replacement knob, pegboard hooks. Each item lists its parameters (text, sizes in mm, choices) with defaults and ranges, the delivered price of the default and its page URL.

### `quote_catalog_item` (~156 tokens)

Quote a customized catalog part

Price a catalog item with the customer's values (e.g. slug "personalized-name-ornament", values {"name": "Leo", "line2": "2026"}). Omitted parameters keep their defaults. We render the part from its parametric source and slice it; returns quote_id, size, grams, price delivered by USPS Ground Advantage and an order_url. Then use price_quote or create_checkout with that quote_id, like any quote.

Input parameters:

- `qty` (integer): How many to price. Default 1.
- `slug` (string, required): Item slug from list_catalog.
- `values` (object): Parameter values by key (from list_catalog). Text up to the listed length; numbers within min and max.

### `design_part` (~108 tokens)

Design a part without a file

For customers without a 3D model (a replacement knob, clip, bracket, box, spacer, enclosure). Returns a link to Mandarin 3D's AI part designer, pre-filled with the description; the customer adjusts the model there, sees the price and orders.

Input parameters:

- `description` (string, required): The part in plain words with measurements in mm, e.g. 'knob for a 6 mm D-shaft, 30 mm wide, 15 mm tall, knurled'.

Mandarin 3D scores 64 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 Mandarin 3D MCP server expose?

Mandarin 3D exposes 7 tools: get_service_info, quote_file, price_quote, create_checkout, list_catalog, and 2 more. Their descriptions and schemas cost roughly 848 tokens of context every time the server is loaded.

### Does the Mandarin 3D MCP server require authentication?

No. We connected to Mandarin 3D without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Mandarin 3D MCP server still maintained?
