## 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 2026-11-05.

- **Endpoint Security**: 74/100
  - 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.
  - 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**: 86/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 980 tokens (~108/item across 9 items; 5 tools + 4 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### 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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-05 (score 75, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-02 (score 74, +1)

## MCP tools (5)

### `generate_pitch_test_chart` (~211 tokens)

Generate a lenticular pitch test chart

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.

Input parameters:

- `heightIn` (number, required): 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, required): Chart width in inches

### `get_print_quote` (~202 tokens)

Get a 3D photo print price estimate

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.

Input parameters:

- `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, required): Print height in inches (0.1-11)
- `quantity` (integer): Number of prints (1-50)
- `widthIn` (number, required): Print width in inches (0.1-16)

### `calculate_output_params` (~211 tokens)

Calculate lenticular print output parameters

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.

Input parameters:

- `heightIn` (number, required): 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, required): Print width in inches

### `get_workflow_guide` (~131 tokens)

Choose the right 3D photo workflow

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.

Input parameters:

- `inputType` (string, required): What the user has

### `get_product_info` (~103 tokens)

Get 3D2HOLO product info and pricing

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.

## Common questions

### What is the 3D2HOLO MCP server?

3D2HOLO is an MCP server listed in the public MCP registry as com.3d2holo/mcp. Lenticular printing toolkit for AI: pitch test charts, print quotes, and workflow guides. This page covers its hosted endpoint (https://backend.3d2holo.com/mcp).

### Is the 3D2HOLO MCP server safe to use?

3D2HOLO scores 75 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 3D2HOLO MCP server expose?

3D2HOLO exposes 5 tools: generate_pitch_test_chart, get_print_quote, calculate_output_params, get_workflow_guide, get_product_info. Their descriptions and schemas cost roughly 858 tokens of context every time the server is loaded.

### Does the 3D2HOLO MCP server require authentication?

No. We connected to 3D2HOLO without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the 3D2HOLO MCP server still maintained?

3D2HOLO 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.
