About 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.

Cursor's Agent mode turns NumVerify into an in-editor superpower. Ask Cursor to generate code using live data from NumVerify and it fetches, processes, and writes. all in a single agentic loop. 4 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

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.

NumVerify + Cursor FAQ

Common questions about integrating NumVerify MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
