mcp-twilio — Twilio MCP Server

Send SMS messages and manage phone numbers from your AI agents.

Twilio is the communications platform that powers SMS, voice, and messaging for tens of thousands of businesses. This MCP server lets your AI agents send text messages, look up message delivery history, and inspect the phone numbers on your account — making it easy to add SMS notifications or two-way messaging to any agent-driven workflow.

What You Can Do

  • Send SMS messages from any Twilio number to any recipient as part of automated notification or alert workflows
  • Check message delivery status and history to verify that critical notifications were received
  • List all phone numbers on the account to understand what numbers are available before building routing logic
  • Pull account balance and status to monitor spend or check if the account is active

Frequently asked questions

What is the Twilio MCP server and what can it do? +

The Twilio MCP server is hosted on Aerostack and exposes these tools to your AI agent: `_ping`, `send_sms`, `list_messages`, `get_message`, `list_phone_numbers`. You get one hosted URL — no self-hosting — that works from Claude, Cursor, ChatGPT, Gemini, VS Code, or any MCP-compatible client, and you can share it with your team or combine it with other MCP servers in a workspace.

Is the Twilio MCP server hosted, or do I have to run it myself? +

It's hosted on Aerostack's edge infrastructure — you don't deploy or maintain anything. Add it to a workspace and you get one authenticated URL, with secrets encrypted, that any AI agent or editor can connect to. Use it solo or share the same URL across your whole team.

Which AI agents and editors can use the Twilio MCP server? +

Any MCP client: Claude and Claude Code, Cursor, ChatGPT, Gemini, Windsurf, Cline, VS Code, and custom agents. Because it's one hosted URL, the same Twilio MCP server works everywhere — and you can compose it with other MCP servers, skills, and functions behind a single workspace URL.

How do I install the Twilio MCP server in Claude Desktop? +

Add the following to your Claude Desktop config (`claude_desktop_config.json`): ```json { "mcpServers": { "@aerostack/mcp-twilio": { "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-twilio"] } } } ``` Then restart Claude Desktop and the tools will appear automatically.

How do I use the Twilio MCP server in Cursor? +

In Cursor, open **Settings → MCP** and add: ```json { "name": "@aerostack/mcp-twilio", "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-twilio"] } ``` Save and reload Cursor. The MCP tools will be available in Agent mode.

Does Twilio MCP require authentication? +

Yes. Twilio requires authentication. Check the MCP's documentation for the required credentials.
