What can I ask?
Turn on the smsmode connector, then ask in plain words. The AI picks the tools.
- How much SMS credit do I have left on my account?
- How many texts did we send last month and what did they cost?
- Show my SMS campaigns and how many messages in each were delivered.
- Were yesterday's appointment reminder texts all delivered?
What you can do with smsmode in Claude and ChatGPT
For teams who send appointment reminders and other text messages with smsmode.
Check your SMS credit balance
The AI reads the credit balance with amount, currency and payment type, and the monthly limit and consumption of the organisation.
See how many texts were sent and what they cost
The AI reads sent-message counts and money spent per month or per day, for all channels or one channel. It can break a record down by country or network.
Check whether messages were delivered
The AI lists sent and received messages with recipient, text and delivery status, including the cause of a failure. It reads one message in full.
Review SMS campaigns and delivery counts
The AI lists campaigns with status, quantity and delivery counts per status, and reads one campaign. Campaigns are read only.
Check channels, sender IDs and limits
The AI lists the SMS and RCS channels with flow, default sender, authorized sender IDs and daily and monthly limits.
Send a text, or cancel one that is still scheduled
The AI sends one SMS to 1 to 10 recipients now or at a set time. It can cancel a message that is still scheduled.
Changes dataHow do I connect smsmode?
Before you connect
The login page asks for your smsmode API key.
Create an API key in your smsmode account under Settings → Developers (ui.smsmode.com/settings/dev). Its role (user, manager or administrator) decides what it can see. Your key is used only to call the smsmode API on your behalf; it is never shown to anyone.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"smsmode": {
"url": "https://smsmode.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"smsmode": {
"type": "http",
"url": "https://smsmode.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
Other clients
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your smsmode API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper organisation | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per organisation | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this smsmode server only. Ask your AI to run smsmode_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with smsmode_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with smsmode_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

smsmode_lookup_numberCountry and mobile network (mcc/mnc, operator) of a phone number. Only for customers with a premium smsmode subscription and, for now, only French numbers (403 otherwise). - List sent and received messages
smsmode_list_messagesMessages with delivery status (SCHEDULED, ENROUTE, DELIVERED, UNDELIVERABLE, UNDELIVERED; status.detail names the cause), recipient, sender, text, parts and price. Default window: the last 10 days. Filter by direction (MT = sent, MO = replies received), recipient, your reference, channel or campaign.

- Send an SMS to 1-10 recipients
smsmode_send_smsWRITE, SPENDS CREDIT: sends one SMS text to 1 to 10 recipients (one message each, a batch of unit messages) and texts REAL people immediately, or at send_at. Cost: every message is charged to the account at its destination's price per SMS part (GSM7: 160 characters for 1 part, 306 for 2, 459 for 3...; UNICODE: 70, 134, 201...); the accept reply returns each message's id and status (the price may only appear later on smsmode_get_message / smsmode_list_messages; total_price is given when present). A batch can partly fail: failures lists the refused numbers, which are not charged. A message is never retried: after a timeout or error, check smsmode_list_messages (ref_client) before sending again. Max 10 recipients, no campaigns or lists. Check smsmode_get_balance first. - Cancel a scheduled message
smsmode_cancel_scheduled_messageWRITE: cancels ONE message that is still scheduled (status SCHEDULED, sent with send_at) so it is not sent; smsmode refuses messages already sent. Cannot be undone.
Your usefulapi plan · 4
- Usage status (free-tier meter)
smsmode_usage_statusReport the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. - Request a missing feature
smsmode_request_featureTell usefulapi that the user needs something the smsmode tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. - Upgrade to Pro or Pro+
smsmode_upgradeGet a paid plan for smsmode (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
smsmode_cancel_subscriptionCancel the caller's smsmode Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run smsmode_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with smsmode in Claude or ChatGPT?
Check your SMS credit balance. See how many texts were sent and what they cost. Check whether messages were delivered. Review SMS campaigns and delivery counts. Check channels, sender IDs and limits. Send a text, or cancel one that is still scheduled. See what you can do for the details.
Is this an official smsmode product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by smsmode. The server calls the smsmode API with your own smsmode access, so it sees only the data that your account can see.
Can I connect smsmode to Claude or ChatGPT?
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
What do I need to connect?
The login page asks for your smsmode API key. See Before you connect for where to find it.
Do I put my smsmode key or an Authorization header in the client config?
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your smsmode API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
How do you keep my smsmode credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the smsmode API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in smsmode.
Can the AI change my smsmode data?
Yes, if you approve it. 2 of the 13 smsmode tools can create or change data. The other 11 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
What does it cost?
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this smsmode server only. Cancel any time: your paid plan then runs to the end of the paid period. Run smsmode_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run smsmode_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run smsmode_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a smsmode tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with smsmode_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Which AI clients can I use?
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
