What is the Phone Validator Engine MCP Server?
LLMs often accept chaotic phone number inputs or try to format them incorrectly before sending to Twilio or Zenvia. This MCP brings Google's libphonenumber-js to the Edge.
The Superpowers
- E.164 Strict Format: Cleans and formats chaotic inputs into mathematically perfect E.164 strings.
- Country Validation: Validates the exact country code and identifies fake numbers immediately.
Built-in capabilities (1)
Pass the raw phone string and optionally a country code. The engine uses libphonenumber to validate structure, detect carrier type, and format to E.164 standard. Validates and formats a phone number deterministically to E.164 standard using Google libphonenumber-js
