Overview

AI-generated overview

A local MCP server for Twilio that lets an assistant send SMS and WhatsApp messages, place calls, run 2FA verifications, validate phone numbers and manage TwiML

What you can do
Send and manage SMS and WhatsApp messages, including listing and deleting message history and listing messaging services and provisioned numbers, plus buying new phone numbers and listing call recordings and incoming numbers
When to use it
Use it when an assistant needs to send SMS or WhatsApp messages, place or modify voice calls, run phone-based 2FA checks, validate phone numbers, or manage Twilio numbers and conversations from a chat session.
Requirements
Runs locally as an npm package over stdio (npx). Needs Node.js and a Twilio account with TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN set; TWILIO_MESSAGING_SERVICE_SID is optional as a default sender. Network access to Twilio APIs is required.
Before you install
The auth token is a secret that grants full account access. Tools can send messages and place calls that cost money, buy phone numbers, delete message history, and change in-progress calls. WhatsApp sending requires approved senders or sandbox numbers. Message content and phone numbers go to Twilio.

Installation

In SourceWeft

  1. Open Mcp Twilio in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

MCP server for Twilio — the global standard for programmable messaging and voice.

SMS, WhatsApp, and Voice across 180+ countries. Verify (2FA) and Lookup (phone validation) included. Fills the global messaging gap in a catalog otherwise tilted to Brazil-specific providers (Z-API, Take Blip, Zenvia, Evolution API).

Install

bash
npm install @codespar/mcp-twilio

Environment

bash
TWILIO_ACCOUNT_SID="AC..."             # requiredTWILIO_AUTH_TOKEN="..."                # required (secret)TWILIO_MESSAGING_SERVICE_SID="MG..."   # optional; default sender for send_message

Authentication

HTTP Basic auth with AccountSid:AuthToken. The server handles this automatically — you only configure the env vars.

Authorization: Basic <base64(AccountSid:AuthToken)>

API surface

  • Main Accounts API: https://api.twilio.com/2010-04-01/Accounts/{AccountSid} — Messages, Calls, IncomingPhoneNumbers
  • Verify API: https://verify.twilio.com/v2 — 2FA flows (requires a Verify Service SID passed per call)
  • Lookups API: https://lookups.twilio.com/v2 — phone number validation / carrier / line type

Request bodies are application/x-www-form-urlencoded; responses are JSON (endpoints use the .json suffix on the Accounts API).

WhatsApp

Use the same send_message tool, but prefix numbers with whatsapp::

json
{ "To": "whatsapp:+5511999999999", "From": "whatsapp:+14155238886", "Body": "Olá" }

Sandbox numbers or approved WhatsApp-enabled senders work the same way.

Run

bash
# stdio (default — for Claude Desktop, Cursor, etc)npx @codespar/mcp-twilio
# HTTP (for server-to-server testing)MCP_HTTP=true MCP_PORT=3000 npx @codespar/mcp-twilio

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
