What is the Twilio SMS Sender MCP Server?
We refused to build a bloated communication suite that tries to manage Twilio Voice, Video, and complex routing studio flows. Instead, this MCP server provides a surgical, zero-trust bridge: just sending SMS text messages.
Your AI agent gains the immediate, zero-friction ability to drop critical 'wake-up' alerts or customer notifications straight to any mobile phone via SMS, bypassing internet-dependent chat apps.
The Superpowers
- Out-of-Band Delivery: When Slack is down or internet is spotty, SMS gets through. If you provide the Twilio credentials, your AI can text directly to cell phones.
- Zero-Bloat Integration: No massive SDKs or complex webhook handlers needed. Just an Account SID, Auth Token, and a 'From' number.
- Absolute Containment: Because this is strictly a sending tool, the agent cannot read your incoming messages, cannot answer phone calls, and cannot alter your Twilio account settings. It is the purest, safest way to give your AI SMS superpowers.
Built-in capabilities (1)
Provide the destination phone number in E.164 format (e.g., +1234567890) in the "to" parameter, and the text in the "body" parameter. Send an SMS text message to a mobile phone number using Twilio

Frequently asked questions
Can the agent read incoming SMS replies with this?
No. This MCP utilizes the REST API strictly for creating new messages. It does not configure or expose incoming webhooks, meaning it acts strictly as a one-way notification megaphone. It cannot see your replies.
Do I need a paid Twilio account?
You can use a Twilio Trial account, but trial accounts can only send SMS to pre-verified phone numbers. To send SMS to any number, you must upgrade your Twilio account.
How does Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
