## 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 2026-10-23.

- **Endpoint Security**: 80/100
  - 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 39/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (fair).
  - Context-footprint check failed: tool/resource definitions use about 615 tokens (~123/item across 5 items; 4 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 83/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 40% of tool parameters carry a description.
  - Structured output schemas are declared (25% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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.
  - Supports UI / widget rendering.

## MCP tools (4)

### `inspect_cad` (~378 tokens)

Inspect CAD file

Open a CAD file on CADProps servers and report its format, size, volume, area, units and accuracy, with an interactive 3D preview. Supported: 3DM, 3DXML, 3MF, 7Z, AMF, ASM, BMP, CATDRAWING, CATPART, CATPRODUCT, CGM, DFT, DRW, DWF, DWFX, DWG, DXF, EMF, F3D, GIF, GLB, GLTF, GZ, IAM, ICO, IDW, IFC, IFCZIP, IGES, IGS, IPT, JPG, JT, NEU, OBJ, PAR, PCX, PDF, PLT, PLY, PNG, PRC, PRT, PSM, RAR, SAB, SAT, SLDASM, SLDDRW, SLDPRT, STEP, STL, STP, SVG, TGA, TGZ, TIFF, U3D, UNV, VDA, VDAFS, VRML, WEBP, WMF, WRL, WRZ, X3D, X3DV, X_B, X_T, ZIP. Creo .prt files with supported saved triangle strips show a partial 3D preview with unverified units and no physical measurements. Other Creo .prt files, Creo .asm files and CATIA .CATProduct files show only the thumbnail saved in the file when available. Call with no file to get a one-time upload link. Files are deleted about one hour after upload.

Input parameters:

- `file` (object)
- `ref` (string): Reference returned by an earlier inspect_cad call.
- `upload_ticket` (string): Ticket from a previous upload link, after the user says the upload is done.
- `wait_seconds` (integer)

Output parameters:

- `area_mm2` (number|null)
- `bounding_box_mm` (object|null)
- `expires_at` (string)
- `failure` (string|null)
- `filename` (string)
- `format` (object)
- `incomplete` (boolean)
- `measurement_accuracy`
- `missing_components` (integer)
- `part_count` (integer)
- `precision_grade`
- `precision_summary`
- `ref` (string)
- `representation` (string|null)
- `source_precision_qualified`
- `status` (string)
- `step_output` (string)
- `units` (object)
- `upload_ticket` (string)
- `upload_url` (string)
- `volume_mm3` (number|null)
- `warnings` (array)

### `convert_cad` (~122 tokens)

Convert CAD file

Convert a file opened with inspect_cad to STEP, STL or GLB and return a download link that expires in 30 minutes. STEP is a solid B-Rep when the source was read exactly; otherwise it is a triangulated STEP that CAD software cannot edit as a solid. STL and GLB are always triangulated meshes.

Input parameters:

- `ref` (string, required): The ref from an inspect_cad result. An upload_ticket is not a ref.
- `step_kind` (string)
- `target` (string, required)
- `wait_seconds` (integer)

### `open_in_workspace` (~77 tokens)

Open in CADProps workspace

Return a one-time link (valid 15 minutes) that opens this file in the CADProps web workspace for measuring, sectioning and sharing. After it is opened, the chat preview and links for this file stop working.

Input parameters:

- `ref` (string, required): The ref from an inspect_cad result. An upload_ticket is not a ref.

### `refresh_view_token` (~29 tokens)

Refresh preview

Used by the CADProps preview to renew its read-only token.

Input parameters:

- `ref` (string, required)

## Common questions

### What is the CADProps MCP server?

CADProps is an MCP server listed in the public MCP registry as com.cadprops/cadprops. Fast multi-format CAD previews, geometry checks and conversion; measure and share in the workspace. This page covers its hosted endpoint (https://www.cadprops.com/api/v1/mcp).

### Is the CADProps MCP server safe to use?

CADProps scores 70 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 CADProps MCP server expose?

CADProps exposes 4 tools: inspect_cad, convert_cad, open_in_workspace, refresh_view_token. Their descriptions and schemas cost roughly 606 tokens of context every time the server is loaded.

### Does the CADProps MCP server require authentication?

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

### Is the CADProps MCP server still maintained?

CADProps is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
