What is the NumVerify MCP Server?

Empower your AI agent to orchestrate your entire phone validation and identity verification workflow with NumVerify, the global API for phone number intelligence. By connecting NumVerify to your agent, you transform complex validation tasks into a natural conversation. Your agent can instantly verify if a number is valid, audit carrier information, and retrieve geographic location data without you ever touching a manual lookup tool. Whether you are cleaning lead lists or verifying user identity, your agent acts as a real-time communications analyst, ensuring your phone data is always verified and accurate.

What you can do

  • Phone Auditing — Verify if any international phone number is valid and retrieve detailed metadata, including country and dial codes.
  • Carrier Oversight — Identify the current carrier for a phone number to maintain a clear view of network distribution.
  • Location Discovery — Retrieve the geographic location (city/region) associated with a phone number instantly.
  • Line-type Intelligence — Identify if a number is a mobile, landline, or VoIP line to optimize your communication strategy.
  • Metadata Integrity — Retrieve official country names and formatting details to maintain strict organizational control over your contact data.

How it works

  1. Subscribe to this server
  2. Enter your NumVerify Access Key
  3. Start managing your phone intelligence through Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Sales Operations — monitor lead lists and retrieve verified phone metadata straight from your workflow.
  • Marketing Managers — verify if contact numbers are valid and audit carrier distribution for SMS campaigns.
  • Security Teams — perform rapid audits of user phone numbers and identify line types through natural language.
  • Operations Leads — automate phone data querying to orchestrate cross-functional communications teams smoothly.

02

Does it support international numbers?

Yes. NumVerify covers over 232 countries and provides detailed validation and metadata for global phone numbers.
