4 use cases

  • Get an SMS verification code for an agent signup

    Let an agent order a number, read the SMS code and close the activation in one run.

    View prompt
    Using the sv-number/mcp-server MCP tools, order a number for service <service code> in country <country id>, then call wait_for_code on its activationId. Expected output: the verification code as returned by wait_for_code, followed by a finish_activation result. Verify that the code is parsed text and not a raw SMS body before you use it.
  • Compare country coverage and delivery rates before ordering

    Check how many countries and how many live numbers exist before spending balance.

    View prompt
    Using the sv-number/mcp-server tools, call list_countries and report the number of rows, then call list_services for <site name> and compare deliveredPercent and online across the top matches. Expected output: a table of country and service options with price, online and deliveredPercent. Verify that every figure comes from a tool response and not from memory.
  • Recover when an SMS code does not arrive

    Ask for another SMS or cancel for a refund when a code never lands.

    View prompt
    Using the sv-number/mcp-server tools, check the activation <activationId> with wait_for_code, then call request_another_sms once if no code arrived, and cancel_activation if it still fails. Expected output: either a parsed code or a cancellation result with the balance from get_balance. Verify that the cancellation result is returned before you report the money as refunded.
  • Generate an authenticator code locally for your own account

    Compute a time-based one-time code on your machine using the totp_code tool.

    View prompt
    Using the sv-number/mcp-server totp_code tool, compute the current authenticator code for <account name> from its secret. Expected output: the current time-based code computed locally by RFC 6238. Verify that the secret is not echoed in the response or in any log before you use the code.

How to use MCP Server

  1. Check you have what it needs: An SV Number account created at https://sms-verification-number.com/en/register/; An API key from https://sms-verification-number.com/en/user/profile/; A funded account balance, since the README says there is no free tier.
  2. Open sv-number/mcp-server on GitHub and read the README and license.
  3. Create an account, fund the balance, and copy your API key from your profile.
  4. Run claude mcp add sv-number --env SVN_API_KEY=your_key_here -- npx -y sv-number-mcp or add the JSON config to your agent.
  5. Call list_services with the site name or domain and pick the best match.
  6. Call order_number with the service code and a country id, then call wait_for_code with the activationId.

These steps come from our top use case, Get an SMS verification code for an agent signup, which also has a copy-paste agent prompt.
