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
Why Cursor?
Cursor's Agent mode turns Twilio SMS Sender into an in-editor superpower. Ask Cursor to generate code using live data from Twilio SMS Sender and it fetches, processes, and writes. all in a single agentic loop. 1 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

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.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
