Integration

SimpleTexting integration

SimpleTexting is an SMS and MMS marketing platform for businesses. Send one-to-one texts and campaigns to lists or segments, evaluate a message's length and credit cost before sending, manage contacts (single and batch create, update, delete), contact lists, segments and custom fields, upload media for MMS, read sent and received messages, and register webhooks for incoming messages, delivery reports and unsubscribes. API access is granted by SimpleTexting on request (email support with your use case). Authentication is the account's API token, sent as a Bearer token in the Authorization header; the token is found in the account settings (Integrations) of the SimpleTexting app. Webhook delivery payloads are documented as callbacks, not callable routes, and are not exposed as tools.

Say what should happen.
The workflow builds itself.

When this happens, do that in SimpleTexting.Built from the 35 SimpleTexting tools below, on the connection you add once.

What you can do with SimpleTexting

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 SimpleTexting from Claude Code, Cursor or Codex

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