Why this exists

EU AI Act Article 50 transparency obligations apply on 2 November 2026 — this is the cliff that DIDN'T move post-Omnibus. The Code of Practice on AI-generated content (finalising May-June 2026) explicitly requires three layers of disclosure for synthetic content:

1. C2PA manifest (Content Credentials) attached to media

2. Invisible watermarking (e.g., SynthID, Tree-Ring)

3. Fingerprinting (perceptual hashes for downstream provenance tracking)

Single-layer C2PA is not sufficient. Most teams don't know this yet. The few open-source tools that exist cover one layer at most.

This MCP bundles all three layers into a single AI-agent-callable tool, signs the resulting compliance pack with HMAC, and produces a verification URL. Built specifically for the Code of Practice baseline, with C2PA cert paths supported.

Real usage example

A media-AI startup serving German + French publishers needed to flip Article 50 disclosure on for every AI-generated image their tool produced. They installed:

pip install meok-watermark-attest-mcp

Prompted Claude during their pipeline integration:

'For every image produced by our generative model, generate a Code-of-Practice-aligned disclosure pack: C2PA manifest with our org cert, SynthID invisible watermark, perceptual fingerprint, and a signed attestation. Embed all three before publishing.'

Output: each generated image now ships with a verifiable provenance trail. When a downstream platform asks 'is this AI-generated?', the answer is a verification URL — not a lawyerly disclaimer. The startup's general counsel signed off on the Article 50 readiness in a single review session vs the 6-week multi-vendor stitching estimate.

EU AI Act Article 50 watermarking + transparency MCP. Built for the 2 November 2026 cliff.

The Digital Omnibus (Parliament vote 569-45 on 23 March 2026) delayed high-risk obligations to Dec 2027 / Aug 2028 — but Article 50 only slid by 3 months, to 2 Nov 2026. That's the next EU AI Act deadline every chatbot operator + GPAI provider + deepfake user must hit.

• Emotion-recognition / biometric-categorisation deployers — Art 50(3) requires informing affected persons

• Deepfake generators — Art 50(4) requires disclosure that content is artificial

• Publishers of AI-generated text on public-interest matters — Art 50(4) text rule
