disclos-article-50

An MCP server that generates the exact EU AI Act Article 50 transparency disclosure you have to show users, in all 24 EU languages, with copy-paste code.

Article 50 is the part of the Act that hits almost every SaaS shipping an AI feature into the EU, and it takes effect on 2 August 2026. This tool hands you the right disclosure text and tells you where to put it, from inside Claude or Cursor.

Built and maintained by Disclos. The companion classifier is disclos-eu-ai-act.

What it does

Two tools:

Tool	What it returns
article_50_disclosure	The visible label for your use case in the language you pick, where and when to show it, and a copy-paste snippet (HTML for chatbots, a machine-readable marker for generated content).
which_article_50_rules_apply	From a few yes/no facts about your product, which Article 50 sub-rules apply, and the use cases to generate.

It covers all four Article 50 duties: AI interaction (50(1)), synthetic content (50(2)), emotion recognition and biometric categorisation (50(3)), and deepfakes (50(4)). Languages: all 24 official EU languages (English, German, French, Spanish, Italian and Dutch are the maintained translations; the other 18 are first-pass and should be reviewed before you rely on them).

TL;DR — install (Claude Desktop)

Add this to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "disclos-article-50": {
      "command": "npx",
      "args": ["-y", "github:GatisOzols/disclos-article-50"]
    }
  }
}

Restart Claude Desktop, then ask:

"I run an AI chatbot with German and French users. Give me the Article 50 disclosure I need to show them."

Claude calls article_50_disclosure and returns the label, the rules, and the HTML to paste in.

Where the text comes from

All 24 EU languages are included here. The six core ones (English, German, French, Spanish, Italian, Dutch) are the maintained Disclos translations, also published in the open-source eu-ai-act-checklist. The canonical generator lives at https://www.disclos.eu/tools/article-50-disclosure-generator.

Accuracy & limits

• The text follows the public structure of Article 50. It is a drafting aid for the common cases, accurate for most straightforward SaaS products.
• Sensitive cases (biometric categorisation, deepfakes of real people) can cross into prohibited or high-risk territory and need a human review.
• English, German, French, Spanish, Italian and Dutch are the maintained translations. The other 18 EU languages are first-pass and should be checked by a native speaker before you rely on them.
• This is general information, not legal advice.
