Before you install MCP Server

AgenticMart scanned MCP Server on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.

What it can access

An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.
Based on its description and topics, it likely needs to read or send messages on your accounts.

Before you install

Use a test account first; check which scopes its token asks for.
Pin the version you reviewed instead of always installing the latest release.
Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.

Tools MCP Server exposes (9)

Listed by the server itself during our scan of commit a57f15f.

get_balance
Current account balance. Ordering a number needs a funded balance; there is no free tier.
list_countries
Every country the numbers can come from, with its id and operators. Use the id in order_number.
list_services
Services available in a country, best match first. Order the code of the site you are registering with: a number bought for one service does not receive another service's SMS. Search by site name or domain, both work. The codes are arbitrary, so look them up instead of guessing: uk is Airbnb, not th
order_number
Order a private number for one service in one country. The number is held for 20 minutes and belongs to this activation alone. Money is held now and charged when the code arrives. The service code has to be the one for the site you are registering with, otherwise its SMS goes to a different pool and
wait_for_code
Wait for the verification code on an ordered number. Polls on its own and returns the code itself, already parsed out of the SMS. Trigger the SMS on the target service first.
finish_activation
Close an activation after the code was used. Do this on every success: a forgotten activation holds money until it expires.
cancel_activation
Cancel an activation when no code arrived; the money returns to the balance in full. Can be called right after ordering. If the API answers that it is too early, wait a couple of minutes and repeat.
request_another_sms
Ask for one more code on the same number, for a password reset or a re-send. Works only after a first code has already arrived; before that the API refuses it.
totp_code
Compute the authenticator code for an account whose second factor was set up with a shared secret. Runs locally by RFC 6238: the secret never leaves this machine.
