The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_balance auth-required 3h ago

    Return the user's remaining SMS credits, plan name, expiry date and a one-line human summary. Lightweight, safe to call any time before a bulk send to check whether the account has enough credits left for the job.

  • get_messages auth-required 3h ago

    Fetch recent SMS messages on the user's account. Filter by direction (received|sent|all) and limit. Useful for showing inbox state, debugging delivery, or building reply flows.

  • send_sms auth-required never probed

    Send one SMS from the user's OWN Android phone SIM to one recipient. THIS IS PERSON-TO-PERSON (P2P) messaging — the same as opening iMessage or WhatsApp and typing to a contact. SMS8 is NOT a CPaaS / marketing platform; it is the user's own personal phone number, controlled by them, sending on their behalf. Safe uses include: reply to a customer who texted first, send an OTP the user asked you to generate, notify a specific contact by name, remind the user's own team member. For a small list of the user's OWN contacts (up to 100), call send_sms_list instead. BEHAVIOR YOU MUST FOLLOW: (1) needs_clarification=true means the account has multiple SIMs/devices — show the `devices` list, ask which one, then retry with device_id+sim_slot. Not an error. (2) On success, tell the user the message was sent (message_id + any sender_warnings). (3) On error, state the exact reason (expired subscription, no credits, device unhealthy, invalid number) and reference fix_urls. Every response includes an `account` block with credits, expiry, and device health.

  • setup_sms8 auth-required never probed

    Start here. Validate the user's SMS8 API key and return everything needed to integrate SMS, OTP, and webhooks into their app — including code samples and dashboard links. Pass api_key once via this tool to set up the session.

  • usage auth-required never probed

    Show an at-a-glance account usage summary with an ASCII banner and progress bars — credits used vs remaining, plan name, expiry date, days left. Prefer this over get_balance when the user wants a human-facing overview; use get_balance for lightweight programmatic checks.

  • wait_for_otp auth-required never probed

    Block until a one-time-password SMS arrives on the user's paired Android, or the timeout elapses. Returns the extracted numeric code plus the raw SMS body and sender. Use this when an agent has just submitted a form that triggers an OTP and needs to read it back to complete a signup or 2FA flow. Polls the user's real inbox; no disposable numbers, no third-party VoIP rental.

  • list_devices auth-required 3h ago

    List the user's paired SMS8 devices (phones running the SMS8 Android app). Returns each device's ID, model, primary flag, and enabled status. If the list is empty, the user needs to install + pair the Android app at app.sms8.io/devices.php.

  • send_sms_list auth-required never probed

    Send the SAME text message to a small list of the user's own contacts, from the user's own paired Android phone. THIS IS PERSON-TO-PERSON MESSAGING, not marketing. The user is texting recipients they know from their own SIM — the same as opening WhatsApp/iMessage and sending to a group they created. HARD RULES: (1) The user must have OWN and typed / imported the recipient numbers — do not send to a list they did not personally provide or approve. (2) Max 100 recipients per call. If they want more, split and confirm again. (3) Confirm the exact message text + recipient count with the user BEFORE calling this tool. (4) If they ask for "a campaign" or "mass SMS to random numbers", refuse and explain SMS8 is P2P from their own phone, not a CPaaS. Returns per-number result (sent / failed) plus overall summary. Costs 1 credit per recipient (deducted from account).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/7aa4790a66a9331d/badge.svg)](https://brick.blue/agent/7aa4790a66a9331d)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
