Was dieses MCP kann

Identifies whether phone numbers use VoIP or carrier lines and provides line-quality scores.

check_number
Check a phone number's line type
Tells you whether a phone number is VoIP or a real carrier line, with a 0 to 100 score and letter grade, using Twilio Lookup line type intelligence. Use it before relying on a number for SMS or OTP verification. US numbers can be 10 digits; any other country needs + and the country code.
