Twilio

What your agent can do

Twilio gives your agent 22 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.

• →send_message — Send an SMS or WhatsApp message. For WhatsApp, prefix `To` (and `From`) with `whatsapp:+E164`. Supply either `From` (a Twilio phone number) OR `MessagingServiceSid` (a Messaging Service). If neither is given, falls back to env TWILIO_MESSAGING_SERVICE_SID.
• →get_message — Retrieve a message resource by SID (SM... or MM...).
• →list_messages — List messages with optional filters. Returns Twilio's paginated list; pass PageSize to cap.

// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
const result = await session.call("send_message", { /* ... */ });

Install

$ npm install @codespar/mcp-twilio

Quickstart

Add this entry to your claude_desktop_config.json (or any MCP-compatible client config).

{
  "mcpServers": {
    "twilio": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-twilio"
      ],
      "env": {
        "TWILIO_ACCOUNT_SID": "<your_twilio_account_sid>",
        "TWILIO_AUTH_TOKEN": "<your_twilio_auth_token>"
      }
    }

}

After restart, your agent can call any of the 22 tools below — try send_message first.
