## Findings

- **warn** Annotations that disagree with the tool in `inspect_cad` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "inspect_cad" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "inspect_cad" says "inspect": a word for reading.
```


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `convert_cad`

- The name "convert_cad" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
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`

- The name "inspect_cad" says "inspect": a word for reading.
- The description's first verb is "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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, GIF, GLB, GLTF, GZ, IAM, ICO, IDW, IGES, IGS, IPT, JPG, JT, OBJ, PAR, PCX, PDF, PLT, PLY, PNG, PRT, PSM, RAR, SAB, SAT, SLDASM, SLDDRW, SLDPRT, STEP, STL, STP, SVG, TGA, TGZ, TIFF, VRML, WEBP, WMF, WRL, WRZ, 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.
```

### `open_in_workspace`

- The name "open_in_workspace" says "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `refresh_view_token`

- The name "refresh_view_token" says "view": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Used by the CADProps preview to renew its read-only token.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `cadprops`:

```json
{
  "permissions": {
    "allow": [
      "mcp__cadprops__refresh_view_token"
    ],
    "ask": [
      "mcp__cadprops__inspect_cad",
      "mcp__cadprops__convert_cad",
      "mcp__cadprops__open_in_workspace"
    ],
    "deny": []
  }
}
