EU AI Act Annex IV Technical Documentation Guide for MCP Systems

How engineering teams map Model Context Protocol configurations, human-in-the-loop gates, and audit logs to Regulation (EU) 2024/1689 Articles 9, 11, 12, 14, 15, 26, and Annex IV.

1. Regulatory Scope & Engineering Disclaimer

With the August 2, 2026 enforcement milestone for high-risk AI obligations under Regulation (EU) 2024/1689, organizations deploying agentic AI systems connected to internal infrastructure via the Model Context Protocol need verifiable technical documentation covering system architecture, risk management, human oversight, and cybersecurity controls.

2. Article-by-Article Control Mapping for MCP Subsystems

• Article 9 (Risk Management System): Continuous identification and automated remediation of privilege escalation (MCP02) and unverified shadow servers (MCP09).
• Article 11 & Annex IV (Technical Documentation): Complete inventory of external MCP tools, pinned package versions (MCP04), and cryptographic SHA-256 lockfiles (mcp-lock.json).
• Article 12 (Record-Keeping & Logging): Structured JSONL invocation logs with secret redaction and 180-day retention (MCP08).
• Article 14 (Human Oversight): Deterministic humanInTheLoop.requireApprovalFor gates before destructive tool calls (MCP07).
• Article 15 (Accuracy, Robustness & Cybersecurity): Protection against secret leakage (MCP01), prompt/tool poisoning (MCP03, MCP06), and command injection (MCP05).
