Abstract Phone Validation MCP

The Abstract Phone Validation MCP server allows AI agents to validate phone numbers and retrieve enriched data including carrier, line type (mobile/landline/voip), and country/location information. It wraps the Abstract API Phone Validation service, requiring users to provide their own API key for authentication.
