Quality Control Plan Generator

Quality Control Plan MCP Server

Generate quality control plans and inspection reports from technical-drawing PDFs — from any MCP-enabled assistant.

This Model Context Protocol server exposes the engine behind quality-check-protocol.imnoo.com (by Imnoo). Need a quality control plan for a technical drawing? Hand the PDF to your assistant and get a numbered inspection plan in about a minute: every dimensional tolerance, ISO fit, thread, geometric tolerance (GD&T) and surface finish is extracted automatically by Imnoo's drawing analysis, ballooned on the drawing and listed with its acceptance limits — ⌀50 ±0.05 becomes 49.95–50.05 — and a measuring instrument. Ask for an inspection class (100 % full inspection, Q1 reduced, Q2 spot check), keep the balloon numbers printed on the drawing or renumber them (1, 001 or D001 style, in reading or measurement order), then let it write the ballooned drawing, the complete inspection package or the Excel measurement and inspection report — the same documents the Imnoo calculator produces. It covers first-article inspection, PPAP-style dimensional reports and shop-floor quality check protocols, on vector and scanned PDFs alike. Built by Imnoo, the planning, scheduling and quoting platform for CNC manufacturers — where the same quality check protocols come out of every quote, next to cost estimation, manufacturing plans and G-code generation.

Tools

Plus a create-quality-plan prompt that walks the assistant through analyze → review → export.

Where the analysis runs. analyze_drawing is the only tool that leaves your machine: it uploads 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 after a short retention period, nothing else is stored. Everything after that — plan building, numbering, acceptance limits, Excel and PDF generation — runs locally and offline.

Installation

Requires Node.js ≥ 18.

Example session

You: Build a Q1 quality plan for C:\drawings\flange.pdf with type-prefixed numbers and write everything next to the drawing.

Assistant: *calls analyze_drawing* — 17 characteristics on 2 pages: 5 dimensional tolerances, 2 drill fits (⌀10 H7 carries the printed balloon 1), 1 shaft fit, 2 threads, 1 fine thread, 2 geometric tolerances, 4 surface finishes; drawing QP-1001-A, article 4711-050, AlMg3, ISO 2768-mK. *calls build_quality_plan with inspection_class: "Q1" and numbering: { style: "typePrefixed" }* — D001 ⌀50 (±0.05) → 49.95–50.05 (Caliper), H001 ⌀10 H7 (Inside micrometer), G001 ⏥ 0.05 (CMM), R001 Ra 3.2 (Surface roughness gauge)… *calls export_inspection_pdf and export_quality_plan_excel with the same plan* — wrote QP-1001-A_inspection-package.pdf (both drawing pages ballooned + the printed plan) and QP-1001-A_Q1.xlsx. Two values on page 2 were read with low confidence — worth a glance before the plan goes to the shop floor.

Those numbers are the bundled sample drawing the smoke test runs against; real drawings vary.

Plan options (the plan argument)

One object, accepted by build_quality_plan and both export tools — pass the same one everywhere so the documents match the reviewed plan. Everything is optional; the defaults reproduce the web app's initial plan.

How the plan is derived

• Acceptance limits exist for plain dimensional tolerances with a numeric nominal (nominal + lower / upper deviation, rounded to 2 decimals). Fits, threads, geometric tolerances and surface finishes are gauged rather than measured against limits — the same rule as the Imnoo calculator.
• Balloon numbers are derived from the selection and the numbering settings, so dropping a characteristic renumbers the rest automatically; a number printed on the drawing is kept in custom order.
• A measured samples value is judged pass / fail against the limits; results and dates appear in both documents.
• The default section order is the measurement workflow: geometric tolerances (CMM) first, surface finishes (roughness gauge) last.

Limitations

• The drawing analysis is automated: it can miss or misread characteristics, especially on low-quality scans — verify the plan against the drawing (rows[].value corrects a value, exclude drops a row).
• Free tier: 1 analysis per day per IP address; PDFs up to 30 MB. Saved analyses (save_analysis_to → load_analysis) are unlimited and offline.
• Hand-drawn characteristics, dragging balloons and saving the plan into the Imnoo calculator are features of the web app only.
• Encrypted or unusual PDFs that cannot be copied fall back to variant: "plan" here (the web app rasterises them instead).

Development

This package is built from the Quality Check Protocol monorepo at Imnoo, where it imports the web app's domain layer directly (drawing mapper, plan math, numbering engine, Excel and PDF builders) — so the web app and this server produce identical plans and documents by construction. Every release is gated on 61 end-to-end checks that drive all five tools over stdio against the bundled sample drawing.
