An MCP server that lets coding agents rent real physical SIM phone numbers and receive SMS verification codes. It supports many countries and online services and runs through an npm package with an API key.

Use it for SMS verification, temporary number rentals, and receiving one-time passwords for supported services and countries.

It provides a phone number and incoming text message for account-verification workflows when the agent needs an SMS code. The service avoids relying on internet-based VoIP numbers.

Security

Grade A, and why

virtualsms scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
