Anonymize technical drawings before you share them — mask company names, logos, people, addresses and contact data on drawing PDFs from any MCP-enabled assistant.
This Model Context Protocol server exposes the engine behind drawing-anonymizer.imnoo.com, the free drawing anonymizer by Imnoo. Sending a drawing to a supplier, a subcontractor or a second source for a quote? Hand the PDF to your assistant and get an anonymized copy in about a minute: Imnoo's drawing analysis finds the sensitive data in the title block, the notes and anywhere else on the sheet — company names, logos, person names, addresses, phone numbers, emails, websites and other identifying text — and the server whites it out (or replaces it with your own company name and logo), masks any extra term or area you name, and writes a tamper-proof, single-layer PDF with the document metadata removed. Article numbers, drawing numbers, dates, dimensions and tolerances stay readable, so the drawing can still be quoted and manufactured. Need to send it right away? Ask for an expiring share link (1 minute to 24 hours) that only ever serves the masked copy. NDA-safe drawing sharing and GDPR-safe drawing exchange, on vector and scanned PDFs alike. Built by Imnoo, the planning, scheduling and quoting platform for CNC manufacturers — where the same automatic drawing masking protects every drawing that leaves a quote.

## Tools
| Tool | What it does |
| analyzedrawing | Uploads a drawing PDF (vector or scanned, up to 4 pages, ≤ 30 MB) to Imnoo's drawing analysis — the service behind the web app — and returns every detection: id, category, value, PDF page, box, confidence, whether it sits in the title block and whether it is masked by default. saveanalysisto keeps the analysis JSON for offline reuse. |
| loadanalysis | Opens a saved analysis JSON. Fully offline — no upload, no daily credit. |
| reviewmasking | Shows exactly what the output will hide and what stays visible: masked detections (with their replacement), detections left visible, custom-term matches, rectangles, the anonymity score (0–100) with its warnings, the output file name, and the text a reader will still see on each page. Deterministic and offline — iterate until nothing identifying is left. |
| maskdrawing | Writes the anonymized PDF: blank (or replacement-text / own-logo) boxes over every masked item; by default every page is then rasterized at 288 dpi so the covered content is destroyed rather than painted over, and author, title, producer and XMP metadata are removed. Optional coverage-report page, page selection and expiring share link. Also accepts pdfpath directly for a one-shot run. |
Plus an anonymize-drawing prompt that walks the assistant through analyze → review → mask.
Where the analysis runs. Uploading the drawing is the only step that leaves your machine: analyzedrawing (or maskdrawing with a new pdfpath) sends the PDF to Imnoo's drawing analysis exactly like the web app does — 1 free analysis per day per IP address (need more? signed-in Imnoo users get a higher daily limit in the web app); uploaded files are deleted automatically within 24 hours and nothing else is stored. Masking, flattening and metadata removal run locally and are unlimited: review and re-mask as often as you like. A share link uploads the masked copy only — never the original.
