Customer address pipelines are notoriously fragile. AI models frequently struggle with regional idiosyncrasies—like knowing a Brazilian CEP needs a hyphen (01311-000), or that a UK Postcode requires a strategic space (SW1A 1AA). The Postal Formatter MCP eliminates these hallucinations by intercepting and validating routing codes via strict V8 Regex engines.

The Superpowers

  • Regional Structural Validation: Instantly rejects structurally invalid data (e.g., rejecting a 4-digit ZIP code or a UK postcode missing letters), returning clear diagnostic reports.
  • Automated Data Cleaning: Receives raw, dirty inputs (like 01311000 or sw1a1aa) and automatically formats them perfectly into standard compliance (01311-000 and SW1A 1AA).
  • Multi-Country Support: Native rules mapped out for Brazil (CEP), United States (ZIP / ZIP+4), United Kingdom (Postcode), and Canada.
  • Zero-Dependency Architecture: Pure JS runtime execution guarantees absolute microsecond speed without any massive geolocation NPM dependencies. Perfect for edge-runtime agentic pipelines.

Format this Brazilian CEP: 01311000

Using the format_postal_code tool (code='01311000', country='BR'): The validated format is '01311-000'.

Is 'SW1A1AA' a valid UK Postcode?

Using the format_postal_code tool: Yes. It is structurally valid and was auto-formatted to 'SW1A 1AA'.

Validate the US ZIP: 1234

Using the format_postal_code tool: Validation failed (`isValid: false`). A US ZIP requires exactly 5 or 9 digits.

No. The Postal Formatter is an algorithmic formatting tool designed for high-speed offline validation. It checks structural integrity (e.g., ensuring a US ZIP has exactly 5 or 9 digits) rather than pinging a geolocation API.
