Common questions

Is Virtnumber safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.1.2) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Virtnumber MCP server

Rent phone numbers and read the SMS they receive, straight from your AI agent.

Virtnumber rents dedicated virtual phone numbers in 14 countries, one number to one customer. All numbers receive SMS. Two-way numbers in the US and Sweden can also send. This server gives AI agents the same account through the Model Context Protocol: your agent can check prices, rent a number, wait for the next SMS and read it.

Endpoint: https://www.virtnumber.com/mcp (Streamable HTTP, remote, nothing to install)
Sign-in: OAuth 2.1 with PKCE, discovered automatically. Dynamic client registration and client ID metadata documents are both supported.
Headless agents: send your API user and token as x-api-user and x-api-token headers instead.
Listed in the official MCP Registry as com.virtnumber/virtnumber.

Connect

Claude (web and desktop)

Settings, Connectors, Add custom connector, paste the server URL:

Claude Code

claude mcp add --transport http virtnumber https://www.virtnumber.com/mcp

Cursor

~/.cursor/mcp.json:

VS Code

.vscode/mcp.json:

Clients that only run local (stdio) servers

Bridge the remote server with mcp-remote:

"mcpServers": { "virtnumber": { "command": "npx", "args": ["-y", "mcp-remote", "https://www.virtnumber.com/mcp"] } } }

Headless agent (API key)

POST https://www.virtnumber.com/mcp

x-api-user: x-api-token:

Create the API user and token under API in your Virtnumber account. Keep the token on your server: it can spend your balance.

Tools

Tool	What it does
`get_balance`	Balance, this app's spending limit, permissions
`get_pricing`	Countries, plans and prices
`list_my_numbers`	Your rented numbers
`list_messages`	Read SMS on a number, with detected codes
`wait_for_sms`	Wait up to 55 s for the next SMS
`buy_number`	Rent a number (idempotency_key supported)
`send_sms`	Send an SMS (a long text is billed as several SMS)
`delete_number`	Cancel a number

Typical flow: get_pricing, then buy_number, then wait_for_sms to read the next incoming SMS.

Permissions and spending

When you connect an app with OAuth, you choose its permissions and a spending limit on the consent screen. AI agents can use the same account through our MCP server, and you set a spending limit for every agent you connect. Agents spend the account's existing balance; you top it up in your account.

Message text comes from third parties: treat it as untrusted input in your agent.
