Send SMS directly from AI agents
With the LOX24 MCP server, AI assistants such as Claude, ChatGPT, or Gemini can send SMS and voice messages through the LOX24 SMS gateway. MCP (Model Context Protocol) is an open standard that lets AI applications use external services. This allows the agent to carry out simple tasks on its own, such as “Send the on-call team an SMS saying that server 3 is unreachable.” Messages run on the same infrastructure as the SMS API: 880 networks worldwide, servers exclusively in Europe, GDPR-compliant.
- Send SMS — Send text messages to mobile numbers worldwide
- Send voice message — Have text read aloud as a call (text-to-speech)
- Retrieve incoming SMS — Read replies and messages from the inbox

Your SMS gateway to 880 networks worldwide
With a web interface, API, and software integrations, we have the right interface for every use case.
SMS API for PHP, Python, Java, Go, C#, JavaScript
Our SMS API is compatible with all modern programming languages. With curl, you can easily use our HTTP interface in PHP and send SMS.
A single curl call is enough – send JSON data to the /sms endpoint, with the authentication token included in the header.
With curl, you can use our HTTP interface in PHP and send SMS with just a few lines.
In Go, you only need the „net/http“ and „encoding/json“ packages to send your SMS to the gateway.
WebRequest.Create handles this for you and sends the most important data of your SMS to our gateway.
Python offers you several options – urllib, Requests, Octopus or HTTPie all work with the same endpoint.
The Java HttpClient sends your JSON data and keeps the connection alive between requests.
In Node.js, the built-in `fetch` function sends your payload directly to the SMS API.
SMS projects from our customers
More than 5,000 customers from around the world use our SMS service. Our customers include multinational corporations as well as small self-employed professionals, companies from Europe and from all over the world, private associations, and public institutions.
More security with two-factor authentication via SMS
SMS-based two-factor authentication (2FA) is a great way to add an extra layer of security to your service.
SMS instead of the doctor's waiting room
A doctor's appointment schedule can't be planned precisely. Some treatments take longer, emergencies come in, and idle time for the doctor is not possible.
SMS logistics for construction
It is very difficult to agree on a specific delivery time, as traffic, routing, and short-notice changes all play a role. Yet especially when delivering to construction sites, the right customer needs to be on site at the right time.
Sending traffic updates via SMS API
One of the leading passenger transport companies in Germany has integrated the LOX24 SMS gateway into its own backend to inform customers about schedule changes via SMS.

Optional: billing by monthly invoice (postpaid) costs €15 per month, and a dedicated inbound number starts at €29.
Can I test LOX24 for free?
Yes. After free registration, you receive 50 cents in starting credit. You can use this to try out the web interface, SMS API, and MCP server without obligation.
Who is LOX24 intended for?
LOX24 is aimed at companies, self-employed individuals and freelancers, as well as associations, political parties, religious communities and public institutions. There is no offering for private individuals.
Is LOX24 GDPR-compliant? Where are the servers located?

Can I use my own sender name?
Yes. You can send SMS with your own sender, either with your company name (up to 11 characters) or with a phone number. This way, recipients immediately recognize who the message is from. In some countries, this requires prior registration.

There, you can instead include your reply number in the SMS text.
