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. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage88
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 65% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_checkout Create a checkout link ~148
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.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | yes | – |
| customer_accepted_terms | boolean | yes | True only if the customer explicitly agreed to the terms sentence above. |
| options | object | – | Optional per-order add-ons. |
| qty | integer | – | – |
| quote_id | string | yes | – |
No output schema declared.
No examples provided.
design_part Design a part without a file ~108
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.

get_service_info Service facts and prices ~73
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'.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_catalog List ready-made parts ~113
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.

quote_catalog_item Quote a customized catalog part ~156
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.
| Name | Type | Req | Description |
|---|---|---|---|
| qty | integer | – | How many to price. Default 1. |
| slug | string | yes | 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. |

No examples provided.
quote_file Quote a 3D model ~191
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.

How do I install the Mandarin 3D MCP server?
Mandarin 3D is a hosted endpoint at https://mandarin3d.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.
