Read account details, contacts, groups, SMS history, numbers and opt-outs. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the SMSGlobal connector, then ask in plain words. The AI picks the tools.
For customer service and operations teams reviewing SMSGlobal messages and contacts.
Review incoming messages, then inspect a selected message’s origin, destination and timestamp to draft a reply in your AI client.
Search outgoing history and inspect the message parts, destination and returned delivery state for a selected message.
Choose a contact group, read its contacts and check the opted-out numbers before preparing a customer follow-up.
Read dedicated numbers, verified origin numbers and sender ID approval states to understand which identities are recorded on the account.
The login page asks for your SMSGlobal REST API key and SMSGlobal REST API secret.
Create REST API credentials in your SMSGlobal MXT account. Use the REST API key/secret pair, not HTTP API credentials. Revoke the key in MXT to revoke vendor access. Login checks your account contact details; billing and usage follow that protected account ID, including when you replace the key. Requested customer messages and contact details pass through UsefulAPI to your chosen AI client and model provider. Credit balance is optional and available only to prepaid customers. This is an independent integration.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"smsglobal": {
"url": "https://smsglobal.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"smsglobal": {
"type": "http",
"url": "https://smsglobal.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
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 SMSGlobal REST API key and SMSGlobal REST API secret. 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.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper account | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per account | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this SMSGlobal server only. Ask your AI to run smsglobal_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 smsglobal_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 smsglobal_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by SMSGlobal. The server calls the SMSGlobal API with your own SMSGlobal access, so it sees only the data that your account can see.
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.
The login page asks for your SMSGlobal REST API key and SMSGlobal REST API secret. See Before you connect for where to find them.
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 SMSGlobal REST API key and SMSGlobal REST API secret. 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the SMSGlobal 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 SMSGlobal.
All 18 SMSGlobal tools are marked read-only.
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 SMSGlobal server only. Cancel any time: your paid plan then runs to the end of the paid period. Run smsglobal_usage_status to see how many calls you used.
Ask the AI to run smsglobal_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 smsglobal_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with smsglobal_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.
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.
