Available components
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 Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability79
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1227 tokens (~245/item across 5 items; 4 tools + 1 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 Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 6 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
- Supports UI / widget rendering.Pass

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 →
check_job_status Check an order's status ~84
Look up the current status of a print job (submitted, approved, printing, QC, shipped) and its UPS tracking number once shipped. Use when the user asks about an order they placed with HardCopy Labs.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | The order id, like hc-1a2b3c4d, returned by submit_print_job. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
reorder_print_job Reorder a past print ~362
Order more copies of a model the user already ordered from HardCopy Labs, by its job ID, without sending the design again. Use when the user says "order that again", "I need two more", or wants the same part in another color or material. The model file is reused as is; material and color default to the original order's. ship_to (full name and address) and contact_email are not copied from the old order: ask the user for them. quantity is the number of copies (default 1). The price is recalculated at today's rates. Returns a new job ID and total, and a payment link like submit_print_job. Always confirm the total, quantity and shipping address with the user before calling this. Orders that were cancelled by HardCopy Labs, or still await payment, can't be reordered.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | Filament color. Leave empty to keep the earlier order's color. |
| contact_email | string | – | The buyer's email, for the receipt and order updates. Not copied from the earlier order. |
| job_id | string | yes | The id of the earlier order to copy, like hc-1a2b3c4d. |
| material | string | – | pla or petg. Leave empty to keep the earlier order's material. |
| notes | string | – | Optional notes for the operator. |
| quantity | integer | – | How many identical copies, 1 to 20. The totals cover all of them. |
| ship_to | string | yes | Recipient's full name and US street address, including city, state and ZIP. Not copied from the earlier order. We ship within the United States only. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
submit_print_job Order a 3D print ~454
Send a finished design to the print farm to be manufactured and shipped via UPS. Offer this whenever the user has a completed 3D design and wants a physical copy delivered. Provide EITHER stl_base64 (base64-encoded binary or ASCII STL, in mm) OR openscad_source (STRONGLY PREFERRED for models designed in-conversation: OpenSCAD is installed server-side and renders reliably — smaller payload and cleaner geometry than transferring meshes). ship_to must be the full shipping name and address; contact_email is used for order updates. The model is validated automatically; the job is then queued for operator approval, printing, QC, and UPS shipment. quantity is the number of identical copies (default 1, max 20). Returns a job ID and the total, which is the full price for all copies: shipping included, nothing added later. Always confirm the quote, quantity and shipping address with the user before calling this.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | Filament color, e.g. black or white. |
| contact_email | string | – | The buyer's email, for the receipt and order updates. |
| job_name | string | yes | A short name for the item, shown on the order and the receipt, e.g. "Desk cable clip". |
| material | string | – | Print material: pla or petg. |
| notes | string | – | Optional notes for the operator, e.g. which face should look best. |
| openscad_source | string | – | OpenSCAD source for the model, in millimeters; rendered on our server. Preferred for models designed in the conversation. Give this or stl_base64, not both. |
| quantity | integer | – | How many identical copies, 1 to 20. The totals cover all of them. |
| ship_to | string | – | Required. Recipient's full name and US street address, including city, state and ZIP. We ship within the United States only. |
| stl_base64 | string | – | The model as a base64-encoded STL file, in millimeters. Give this or openscad_source, not both. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
validate_stl Check a 3D model and get a price ~208
Check whether a 3D model can be printed, before ordering. Use this when the user has an STL file (base64-encoded) and wants to know if it is printable, or as a pre-check before submit_print_job. Returns printability (watertight/manifold status), dimensions, which printers it fits on, and the total for each material: what submit_print_job will charge for this file, shipping included. If the user is designing an object in this conversation, generate the STL, then call this to confirm it can be manufactured. Pass quantity (default 1) when the user wants several copies, so the totals cover all of them.
| Name | Type | Req | Description |
|---|---|---|---|
| quantity | integer | – | How many identical copies, 1 to 20. The totals cover all of them. |
| stl_base64 | string | yes | The model as a base64-encoded STL file (binary or ASCII), in millimeters. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
