Classify any AI system under the EU AI Act: risk tier + binding Articles, verbatim from the law.
This Model Context Protocol server exposes Leo — the deterministic classifier for Regulation (EU) 2024/1689 (the EU AI Act), as amended by Regulation (EU) 2026/1744 (the Digital Omnibus on AI, in force 27 July 2026) — as callable tools. Every answer is grounded verbatim in the official law. Leo never guesses.
When a user asks an AI "is my AI system high-risk under the EU AI Act?", the honest answer must cite the actual law — not a hallucination. This server lets your agent do exactly that.
| Tool | What it does |
|---|---|
classify_ai_system | Plain-language AI description → risk tier (prohibited / high-risk / limited / minimal) + the exact Annex III category and binding Articles. |
lookup_article | Verbatim text of any Article (1–113 of the 2024 text; amended articles are flagged on the site). |
search_eu_ai_act | Full-text search across Articles, Recitals and Annexes. |
get_compliance_deadlines | The application dates in force under Regulation (EU) 2026/1744 (statuses computed at call time) and the Article 99 fine tiers. |
Add to your claude_desktop_config.json:
{
"mcpServers": {
"sovereign-ai-act": {
"command": "npx",
"args": ["-y", "sovereign-ai-act-mcp"]
}
}
}
Restart Claude, then ask: "Is an AI that screens job applicants high-risk under the EU AI Act?" — Claude calls Leo and answers with the exact Articles.
Works the same in Cursor, VS Code, Windsurf, Cline, and any MCP-capable client.
