# 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](https://disclos.eu). The companion classifier
> is [disclos-eu-ai-act](https://github.com/GatisOzols/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):

```json
{
  "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.

## Run from source

## 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](https://github.com/GatisOzols/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.**
