CADProps MCP server

Which servers in the official MCP registry are CADProps's own, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.cadprops/cadpropsverified in the MCP registry

The registry name sits under cadprops.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-19 the server answered initialize and tools/list without a sign-in. First answer in 668 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: check part dimensions in a browser viewer without desktop CAD; export supported models to STEP for handoff.
  • Checked on 3 of the 7 days it takes to judge reliability.

Once connected

  • For "check part dimensions in a browser viewer without desktop CAD", the likely first call is inspect_cad.
  • For "export supported models to STEP for handoff", the likely first call is inspect_cad.
  • Parameters are untyped or undescribed in 3 of 4 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

  • not sure · estimate mass from solid volume and chosen material density
  • can do · export supported models to STEP for handoff

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • inspect_cad

    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…

  • convert_cad

    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…

  • open_in_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.

  • refresh_view_token

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

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "cadprops": {
      "type": "http",
      "url": "https://www.cadprops.com/api/v1/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http cadprops https://www.cadprops.com/api/v1/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://www.cadprops.com/api/v1/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
