## What it does

This server prepares manufacturing drawings for third parties under NDA or privacy requirements. The `analyze_drawing` tool uploads a vector or scanned drawing up to 30 MB and 4 pages to the Imnoo analysis backend. The system marks contact blocks, vendor names, and logos, leaving dimensions, notes, and tolerances legible for quoting.

Review and redacting stages run locally. The `review_masking` tool reports a privacy score from 0 to 100 alongside any text that remains visible. Afterward, `mask_drawing` covers sensitive zones with blank areas or custom company markers, removes document metadata, and turns pages into a flattened 288 dpi raster to stop reverse-engineering.

Unregistered visitors get a strict limit of one free drawing analysis per day per IP address, and running the package requires Node.js version 22.13 or newer.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `DRAWING_ANONYMIZER_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Platform CLI**
```bash
claude mcp add --env DRAWING_ANONYMIZER_URL=<DRAWING_ANONYMIZER_URL> --transport stdio drawing-anonymizer -- npx -y drawing-anonymizer-mcp
```
Replace <…> with your own values

### Codex

**Platform CLI**
```bash
codex mcp add drawing-anonymizer --env DRAWING_ANONYMIZER_URL=<DRAWING_ANONYMIZER_URL> -- npx -y drawing-anonymizer-mcp
```
Replace <…> with your own values

            ],
            "env": {
                "DRAWING_ANONYMIZER_URL": "<DRAWING_ANONYMIZER_URL>"
            }
        }
    }
}
```
Replace <…> with your own values

### GitHub Copilot

**Config file**

            ],
            "env": {
                "DRAWING_ANONYMIZER_URL": "<DRAWING_ANONYMIZER_URL>"
            }
        }
    }
}
```

### Gemini CLI

**Platform CLI**

```
Replace <…> with your own values

## When to use it
- Mask client names and logos on CAD sheets before subcontractor quoting
- Flatten PDF layers into a single raster to prevent text recovery
- Generate time-limited expiring links for redacted engineering drawings
- Replace customer identity fields with your own company branding

## Example prompts
- Anonymize `bracket.pdf`, replace the client logo with our company name, and output a flattened file
- Run review masking on the saved analysis JSON and check what text remains visible
- Mask sensitive fields on `flange.pdf` and create a share link that expires after 2 hours
