Integration

Smstools integration

Smstools is a Belgian SMS gateway (smstools.com, API host smsgatewayapi.com). Send an SMS to a number or to a whole contact group, or a voice call that reads a text out loud, now or at a set time, with your own text or a saved template, or validate a send in test mode; follow a message's delivery status and replies, list sent history, scheduled messages (and remove one), received inbox messages and the conversation with a number; list, search, add, update and remove contacts, list, read and add contact groups, list sender ids, subaccounts and message templates, read the credit balance and sent and received counts, put a phone number in international format, and list, add or remove opt-outs. Messages and contacts are personal data, and sending costs credits. Not exposed: WhatsApp, flows, conversation assignment, webhooks, birthday messages, white label accounts, account details, virtual numbers, grouped history, per-subaccount history and statistics, and renaming or deleting groups or managing templates, sender ids and subaccounts. Authentication is an API client ID and client secret (Developer, API and Webhooks, API credentials) sent in the X-Client-Id and X-Client-Secret headers.

Say what should happen.
The workflow builds itself.

When this happens, do that in Smstools.Built from the 27 Smstools tools below, on the connection you add once.

What you can do with Smstools

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Use Smstools from Claude Code, Cursor or Codex

Connect Smstools in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Smstools operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Set up the MCP server step by step
