Perplexity

Team-wide compliance tools

By committing the MCP config file, every developer on the team gets automatic access to VAT validation. The agent uses `validate_vat` to verify tax IDs before code is even committed. This guarantees that all team members rely on the same validated source of truth for B2B compliance.

Enterprise-grade reliability

The tool operates within a shared, repository-level configuration, making it suitable for large engineering teams. It uses robust mathematical checks to validate European and international tax numbers. It’s designed for enterprise use cases where consistency is non-negotiable.

Integrated validation workflow

When switching Copilot Chat into Agent mode, the AI can call `validate_vat` as part of a larger task. You ask it to check multiple tax IDs, and it returns structured data confirming which ones pass format checks. This keeps your compliance logic centralized and easy to review.
