You: "Explain the difference between R155 and ISO 21434"

Claude: "Based on the sources:

📋 UNECE R155 (Regulation):
- Legal requirement for vehicle type approval in EU/Asia
- Focus: What you MUST have (CSMS, processes, documentation)
- Enforced by: Government regulators during type approval
- Consequence: Can't sell vehicles without it

📘 ISO 21434 (Standard):
- Industry best practice (not legally required)
- Focus: How to implement automotive cybersecurity engineering
- Provides: Detailed processes, methods, work products
- Used to: Demonstrate compliance with R155

Relationship: R155 says 'you must have a CSMS', ISO 21434 tells you how to build one."

Yes, for reference. The regulations (R155/R156) are public domain. However, always verify critical compliance decisions with the official source documents. This tool helps you work faster, not replace your judgment.

How much ISO 21434 content is included?

25 clauses with expert guidance. ISO 21434 is copyrighted—we include clause titles, expert guidance summaries, work products, and R155 mappings (not full text). This covers all major clauses (5-15) plus key annexes. R155/R156 regulations are public domain and fully included.

Can I use this for paid client work?

Yes. Apache 2.0 license allows commercial use. Many consultants use this to speed up their R155/ISO 21434 advisory work.

What about ISO 21434 full text?

Not included (copyright). We provide clause IDs, titles, and expert guidance for ISO 21434. The full standard text requires a license from ISO. This approach respects copyright while still being useful.

Will this work with Claude Pro / Claude API?

Claude Desktop only for now. MCP is currently supported in Claude Desktop. Once Anthropic adds MCP support to web/API, this will work there too (no changes needed).

How do I get updates?

Automatic. If you install via npm/npx, running npm update -g @ansvar/automotive-cybersecurity-mcp (or just restarting Claude Desktop with npx) will get the latest version. v1.0.0 includes all Phase 1 & 2 features.

Can I add my own company's interpretations?

Yes. Fork the repo and modify data/seed/*.json files to add internal notes, then rebuild the database with npm run build:db.

Is my data sent anywhere?

No. Everything runs locally on your machine. The database is read-only SQLite. No network calls, no telemetry, no data collection.

Important Disclaimers

⚖️ Legal & Compliance

Not Legal Advice: This tool provides access to regulatory text for informational purposes only. It does not constitute legal advice, compliance certification, or professional consultation. For official compliance decisions, consult qualified legal counsel or type approval authorities.

Official Sources: Always verify critical requirements against official UNECE publications and your jurisdiction's implementation of regulations.

Type Approval: Type approval decisions are made by recognized technical services and approval authorities, not by AI tools.

📊 Token Usage

Claude Desktop: This MCP can return large regulation articles (e.g., R155 Article 7 is 22KB). Be mindful of token usage if on limited plans.

Best Practice: Use specific queries rather than requesting entire regulations at once.

📜 ISO Standards

ISO 21434 Content: Full ISO 21434 text is copyright-protected and not included. We provide expert guidance summaries only. Purchase the official standard from ISO for complete requirements.

Directory Review Notes

Testing Account and Sample Data

This server is read-only and does not require a login account for functional review. For directory review, use the bundled dataset and these sample prompts:

• "What does R155 Article 7 require for CSMS?"
• "Search R156 requirements for software update assessment."
• "List ISO 21434 work products for TARA."

Remote Authentication (OAuth 2.0)

The default server runtime is read-only and can be deployed without authentication. If you deploy a remote authenticated endpoint, use OAuth 2.0 over TLS with certificates from recognized authorities.

Privacy

See PRIVACY.md for data handling and retention notes.

Troubleshooting

• If the server is not discovered in a client, verify the command path and that npm run build completed successfully.
• If tool calls fail, confirm data/automotive.db exists and the process can read it.
• If no results are returned, try broader search terms first (for example, R155, R156, or ISO 21434) and narrow from there.
