Integration

Sinch MessageMedia integration

Sinch MessageMedia (formerly MessageMedia) is a business SMS, MMS and text-to-voice platform. Send and schedule messages, read delivery reports and replies and confirm them, check and edit the opt-out blacklist, manage contacts, contact lists and custom fields, register and verify sender IDs, find and assign dedicated numbers, manage event webhooks, read short-link click reports, run detail, insight, asynchronous and scheduled message reports (v2-preview), and build Mobile Landing Page campaigns (beta, APAC instance only). The callback signature key routes are not exposed: a signature private key is a secret. Authentication is HTTP Basic with the API key as username and the API secret as password; api_host is api.messagemedia.com (APAC instance) or eu.app.api.sinch.com (EU instance).

The workflow builds itself.

What you can do with Sinch MessageMedia

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 Sinch MessageMedia from Claude Code, Cursor or Codex

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