Integration

Telesign integration

Telesign is a communications and digital identity platform. Send SMS (one recipient or up to 1000 at once) and track delivery, send messages by SMS, MMS, WhatsApp, RCS, Viber or email with fallback channels through the Messaging API and manage its SMS and WhatsApp templates, check whether a phone number can receive RCS (optionally from a given RBM agent), send one-time passcodes by SMS or voice call and check the code the user typed, run multi-channel verification processes with Verify API, look up a phone number's carrier, type, location and live status with Phone ID, score the fraud risk of a phone number or email address with Intelligence, and open masked SMS or voice sessions between two people. Several products must first be enabled on the Telesign account (Telesign says so per product). Left out: Voice call control and call recordings (they need a callback server), App Verify and Silent Verify (driven from a mobile SDK), the deprecated Score, Smart Verify and legacy Phone ID routes, deactivated-number file downloads, the Flow Builder and Protect platform APIs, and account, API key and SCIM user administration. Authentication is HTTP Basic: the Customer ID as username and an API key as password, both from the Telesign portal.

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in Telesign.Built from the 24 Telesign tools below, on the connection you add once.

What you can do with Telesign

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.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Use Telesign from Claude Code, Cursor or Codex

Connect Telesign in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Telesign 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
