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 Security80
- 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
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability39
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (fair).Partial
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management33
- Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage83
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 40% of tool parameters carry a description.Partial
- Structured output schemas are declared (25% 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
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

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 →
convert_cad Convert CAD file ~122
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.

inspect_cad Inspect CAD file ~378

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.

How do I install the CADProps MCP server?
CADProps is a hosted endpoint at https://www.cadprops.com/api/v1/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.

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.
