@eucomplyhub/mcp-eu-ai-act

MCP (Model Context Protocol) server exposing free EU AI Act compliance classifiers to AI assistants. Built for Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Powers AI assistants to evaluate mid-market SaaS systems against EU AI Act, NIST AI RMF, ISO/IEC 42001, OECD, GDPR, and sector-specific overlays.

⚡ TL;DR (60-second install)

npm install -g @eucomplyhub/mcp-eu-ai-act

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

{
  "mcpServers": {
    "eucomplyhub": {
      "command": "npx",
      "args": ["-y", "@eucomplyhub/mcp-eu-ai-act"]
    }
  }
}

Restart Claude Desktop. Ask:

"Classify Acme Inc — an HR-tech SaaS using AI to score candidates for B2B enterprise customers."

Claude returns full Annex III mapping, Article 50 transparency obligations, GPAI Article 53 reasoning, and 5 priority remediation actions tailored to the deployment.

🆚 How does this differ from other EU AI Act MCP servers?

There's one other EU AI Act MCP server in the awesome-mcp-servers Legal section (@ark-forge/mcp-eu-ai-act). It's a different scope:

Use whichever fits your scope. They're complementary, not competitive.

🎬 Sample Claude Desktop output

> Classify Acme Inc — HR-tech SaaS using AI to score candidates for B2B enterprise customers.

Running classify_annex3...

Overall risk: HIGH-RISK
Summary: Acme operates in Annex III §4 (employment), with AI-driven
candidate scoring affecting hiring decisions. Article 50 disclosure
applies. EU customers trigger full obligations.

Annex III categories:
  III.4 Employment           ✓ YES   — AI ranking influences hiring
  III.5 Essential services   — NO    — not credit/benefit scoring
  [...6 more categories...]

Article 50: APPLIES
  Reasoning: Candidates interact with AI-generated outputs;
  transparency disclosure required at the point of evaluation.

GPAI Article 53: deployer (you consume third-party foundation model)
  Reasoning: Score generation via OpenAI/Anthropic API → you're
  not the provider, but Article 26 deployer obligations apply.

Priority remediation actions:
  1. Implement Article 14 human oversight UI — manager confirmation
     step before AI-ranked candidates auto-proceed
  2. Add Article 50 transparency banner — "AI-assisted scoring"
     notice visible to candidates
  3. Document training data lineage (Article 10) — if Acme fine-tunes
  4. Establish post-market monitoring (Article 72)
  5. GDPR overlap — DPIA required (Annex III high-risk = Art 35 trigger)

Install

For Claude Desktop

1. Install the package globally:

   npm install -g @eucomplyhub/mcp-eu-ai-act

2. Edit your Claude Desktop config file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

   • Windows: %APPDATA%\Claude\claude_desktop_config.json

3. Add the server:

         "args": ["-y", "@eucomplyhub/mcp-eu-ai-act"]
       }
     }
   }

4. Restart Claude Desktop.

5. In a new chat, ask:

   Use the eucomplyhub tools to classify Acme Inc — an HR-tech SaaS with CV screening features for European enterprise customers.

   Claude will call classify_annex3 and return a structured Annex III mapping + priority remediation actions.

For Cursor

Add to .cursor/mcp.json (workspace) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "eucomplyhub": {
      "command": "npx",
      "args": ["-y", "@eucomplyhub/mcp-eu-ai-act"]
    }

  "mcpServers": {
    "eucomplyhub": {
      "command": "npx",
      "args": ["-y", "@eucomplyhub/mcp-eu-ai-act"]
    }
  }
}

Generic stdio client

npx -y @eucomplyhub/mcp-eu-ai-act

The server runs over stdio (standard MCP transport).

Example prompts

Once installed, ask your AI assistant questions like:

• "What's the EU AI Act risk class for an HR-tech SaaS using AI to score job candidates?"

• "Run the quick risk classifier for a healthcare diagnostic AI used by EU regulated medical providers."

• "Deep-classify Acme Inc — they're a B2B fintech using AI to score loan applicants in the EU."

• "For Notion AI features, what Annex III categories apply and what's the Article 50 obligation?"

The assistant will call the appropriate tool and return structured results you can act on.

What does this cost?

Free. Both tools call free public endpoints at eucomplyhub.com:

• quick_risk_class runs entirely locally (deterministic JavaScript, no network call)

• classify_annex3 calls https://eucomplyhub.com/api/annex3-classify (rate-limited free public API)

Rate limits apply for abuse prevention. Heavy usage should consider commissioning a full audit via eucomplyhub.com/audit.
