Why this exists

The EU Cyber Resilience Act (Reg 2024/2847) Annex IV defines essential security requirements across nine categories that every product with digital elements sold in the EU must meet — including AI-embedded products. Most teams treat CRA as 'something the security team handles next year'. That's a mistake: the conformity self-assessment + technical-documentation requirements are non-trivial, and the penalties (up to €15M or 2.5% of global turnover) are real.

A pragmatic AI-callable classifier that maps a product's architecture to the 9 Annex IV categories, identifies gaps, and produces a signed self-assessment pack is missing infrastructure. This MCP fills that gap.

Real usage example

An IoT manufacturer with EU sales prepared their CRA conformity self-assessment ahead of the December 2027 application date. They installed:

pip install meok-cra-annex-iv-classifier-mcp

Prompted Claude:

'Classify our smart-thermostat product (firmware in C, cloud backend in Go, mobile app in Swift/Kotlin) against the 9 CRA Annex IV essential security requirements. Identify gaps. Produce a signed self-assessment pack ready for our notified body.'

Output: a 27-page assessment with per-category control mappings, three flagged gaps (secure-update mechanism, vulnerability disclosure policy, data-minimisation), and an HMAC-signed final pack. Saved roughly £18K of external consultancy that would otherwise have been booked for the same deliverable.

EU Cyber Resilience Act product classifier — Annex III + Annex IV designations + Annex I requirements audit + signed certificates.

Classifies products with digital elements (PDEs) into the CRA hierarchy. Built for the 11 Dec 2027 full-applicability deadline (vulnerability + serious-incident reporting already in force from Sept 2026).

Why this MCP

Implementing Regulation (EU) 2025/2392 (adopted late November 2025) just designated the first set of Class I, Class II, and Annex IV product categories. IoT vendors, chipmakers, smart-meter manufacturers, OT teams need a defensible classification NOW — every classification you delay is conformity work you'll pay for retroactively.

What it classifies

• Default class — most consumer / business software (self-assessment, fines max €5M / 1%)

• Important Class I (Annex III(1)) — IAM, password managers, browsers, VPNs, OS, routers, smart home — self-assessment OR Notified Body (€10M / 2%)

• Important Class II (Annex III(2)) — hypervisors, firewalls, IDS/IPS, tamper-resistant µCs/µPs — MANDATORY Notified Body assessment (€15M / 2.5%)

• Critical (Annex IV) — smart-card secure elements, smart-meter gateways, hardware security boxes — mandatory European cybersecurity certification (€15M / 2.5%)

Tools

• classify_product — heuristic classification by description + characteristics

• audit_essential_requirements — score against 15 Annex I cybersecurity requirements

• generate_doc_template — Annex VIII technical documentation skeleton

• sign_classification_cert — Pro: HMAC-SHA256 signed classification cert with public verify URL
