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 Usability86
- 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
- Tool/resource definitions use about 980 tokens (~108/item across 9 items; 5 tools + 4 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability observed for 4 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.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 current MCP spec version (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 →
calculate_output_params Calculate lenticular print output parameters ~211
Calculate technical print parameters for a specific lenticular print: print-ready pixel size, uncompressed file size, views per lens period with and without lens rotation, feasibility of a desired view count, and the recommended lens rotation angle. Use this tool when the user asks numerical print questions — how many pixels are needed, what resolution to use, how many views fit, or what rotation angle to use — providing print width and height plus printer DPI, lens LPI, or desired view count when known. The tool computes values from formulas rather than estimating. Scope: numerical print parameters only; it does not produce calibration charts or price quotes.
| Name | Type | Req | Description |
|---|---|---|---|
| heightIn | number | yes | Print height in inches |
| lpi | number | – | Lenticular lens pitch in LPI, if known |
| resolution | number | – | Printer resolution in DPI, default 720 |
| viewCount | integer | – | Desired number of view frames, if the user has one |
| widthIn | number | yes | Print width in inches |
No output schema declared.
No examples provided.
generate_pitch_test_chart Generate a lenticular pitch test chart ~211
Generate a printable LPI pitch-test chart to measure or calibrate the actual lens pitch of a lenticular sheet. Use this tool when the user has a nominal LPI and wants to verify the real value, calibrate a new lens sheet, or determine the correct lens pitch before interlacing. The chart contains an LPI sweep with alignment marks, intended to be printed at 100% scale and evaluated with the physical lens sheet. The tool outputs an image plus measurement instructions. Scope: physical lens calibration only; it does not compute print dimensions, view counts, or prices.
| Name | Type | Req | Description |
|---|---|---|---|
| heightIn | number | yes | Chart height in inches |
| lpi | number | – | Target (nominal) lens LPI, the center of the sweep, default 60 |
| resolution | number | – | Printer resolution in DPI, default 720 |
| steps | number | – | LPI step between adjacent blocks, default 0.1 |
| widthIn | number | yes | Chart width in inches |
No output schema declared.
No examples provided.
get_print_quote Get a 3D photo print price estimate ~202
Estimate the price of a custom physical 3D2HOLO lenticular photo print when the user asks how much a print will cost. Use this tool when the user provides or asks about print dimensions and quantity. The quote includes the craft fee, lenticular grating/material fee, and shipping estimate, computed from current pricing rather than recalled from memory. Scope: physical print pricing only; the tool does not answer workflow, print-parameter, or calibration questions.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | Shipping destination country/region (optional). Shipments to foreign destinations outside mainland China, Hong Kong, Macau and Taiwan include a 100g packaging box weight in the shipping estimate; omi… |
| heightIn | number | yes | Print height in inches (0.1-11) |
| quantity | integer | – | Number of prints (1-50) |
| widthIn | number | yes | Print width in inches (0.1-16) |
No output schema declared.
No examples provided.
get_product_info Get 3D2HOLO product info and pricing ~103
Get authoritative 3D2HOLO product information: supported workflows, input types, output formats, LPI range, resolution, and pricing. Use this tool when the user asks what 3D2HOLO supports or how much the service costs, instead of relying on remembered or assumed capabilities. Scope: general product and pricing overview; the tool does not compute specific print parameters, generate calibration charts, select workflows for a specific input, or quote a custom print.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_workflow_guide Choose the right 3D photo workflow ~131
Recommend the right 3D2HOLO workflow when the user wants to turn existing visual content into a lenticular 3D photo and their source type is known: a single photo, multi-angle photos, a GLB/GLTF 3D model, a Sketchfab model, or AI-generated multi-view images. The tool returns the recommended workflow steps and where to start. Scope: workflow selection for a specific input type; the tool does not provide product overviews, print-parameter math, calibration charts, or price estimates.
| Name | Type | Req | Description |
|---|---|---|---|
| inputType | string | yes | What the user has |
No output schema declared.
No examples provided.
How do I install the 3D2HOLO MCP server?
3D2HOLO is a hosted endpoint at https://backend.3d2holo.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.
