Use numlookupapi with AI agents (MCP)
numlookupapi ships a hosted Model Context Protocol (MCP) server. AI agents and assistants — Claude, Cursor, VS Code and any other MCP-capable client — can call the API as native tools, no SDK or glue code required.

Connect in seconds
Using Claude Code:
claude mcp add --transport http numlookupapi https://api.numlookupapi.com/mcp --header "apikey: YOUR_API_KEY"
Or add it to any MCP client configuration:
{
"mcpServers": {
"numlookupapi": {
"url": "https://api.numlookupapi.com/mcp",
"headers": { "apikey": "YOUR_API_KEY" }
}
}
}
Listing the available tools works without authentication. To execute tools, sign up for a free API key and send it as the apikey header.
Available tools
| Tool | Endpoint | Description |
|---|---|---|
validateNumber | GET /v1/validate/{number} | Validate a phone number |
getStatus | GET /v1/status | Account quota status |
Tool calls are metered like regular API requests and return the same machine-readable errors, so your agent always knows how to proceed. Full details in the MCP documentation.
