Sms does not always answer

Over the last week it answered 99.1% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

This one needs environment variables set before it will start: VIRTUALSMS_API_KEY (Your VirtualSMS API key from virtualsms.io). The author declared them in the registry entry; get the values from the project itself.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Sms — questions

Answers built from our own checks of this server.

Why is there no tool list for Sms?

The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.

Is Sms working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 895 ms. The bar chart above shows every period we have measured.

How do I connect Sms?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does Sms need an API key?

Yes. Every time we knock, Sms answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Sms?

It answers our handshake in 895 ms on average, which is faster than 11% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Sms?

The npm package virtualsms-mcp was installed 104 times in the last week. Week over week that is -52%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Sms open source?

Yes — it is published under the MIT licence, written in TypeScript and 8 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
