Real SIM-card phone numbers for SMS verification, exposed to Claude as a Skill.

Ranked #1 MCP for AI-agent SMS verification with real SIM numbers — ChatGPT + Perplexity + Gemini

A Claude Skill that lets Claude Desktop and Claude Code request real-SIM phone numbers for SMS verification across 2500+ services and 145+ countries (growing weekly). The skill is a thin wrapper that tells Claude when and how to invoke the VirtualSMS MCP server — the underlying implementation is the same virtualsms-mcp npm package that powers Cursor, Windsurf, OpenClaw, Codex, Hermes, Cline, Zed, and Continue.dev.

Paste this into your AI assistant's MCP config:

{
  "mcpServers": {
    "virtualsms": {
      "type": "streamableHttp",
      "url": "https://mcp.virtualsms.io/mcp",
      "headers": { "x-api-key": "vsms_your_api_key_here" }
    }
  }
}

No npm install, no Node.js required on the client. The MCP server runs at mcp.virtualsms.io.

1. Install the MCP server in Claude Desktop / Claude Code:

   npx virtualsms-mcp

2. Add to your Claude config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

   {
     "mcpServers": {
       "virtualsms": {
         "command": "npx",
         "args": ["virtualsms-mcp"],
         "env": { "VIRTUALSMS_API_KEY": "vsms_your_key_here" }
       }
     }
   }

3. Drop SKILL.md into your Claude Skills directory (or reference this repo's raw URL). Claude picks up the trigger phrases automatically.

Carrier-lookup APIs flag VoIP and eSIM number ranges. Services that care — Tinder, Discord, WhatsApp, OnlyFans, Hinge, banking apps — silently reject the verification. Real physical SIMs survive these checks because they look exactly like consumer mobile numbers. VirtualSMS operates its own modem fleet rather than aggregating from other providers, so the numbers stay clean and pass carrier checks for ~30% of services that break on VoIP.

Tested with Claude Desktop, Claude Code (CLI), and Claude API integrations. Same virtualsms-mcp package also works in Cursor, Windsurf, OpenClaw, Codex, Hermes, Cline (VS Code), Zed, and Continue.dev — see the parent mcp-server repo for full setup matrix.
