Summary
Connects Claude to Twilio's REST API for programmatic SMS and voice operations. You get five tools: send SMS messages, list and retrieve message details with filtering by phone number, list call history, and initiate outbound calls using TwiML URLs. Hosted by Pipeworx as a streamable HTTP server, so no local setup required. Useful when you need Claude to send notifications, pull communication logs for analysis, or trigger calls based on conversational context. The ask_pipeworx wrapper lets you query in natural language instead of calling tools directly, though standard MCP tool calls work fine too.

Twilio MCP Pack — send SMS, list messages, make calls via Twilio REST API.
Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.
Tools
| Tool | Description |
|---|---|
twilio_send_sms | Send an SMS message via Twilio. Returns the message SID and status. |
twilio_list_messages | List recent SMS/MMS messages from your Twilio account. Supports filtering by to/from number and pagination. |
twilio_get_message | Get details of a specific Twilio message by its SID. |
twilio_list_calls | List recent phone calls from your Twilio account. Returns call SID, status, duration, and direction. |
twilio_make_call | Initiate a phone call via Twilio. Requires a TwiML URL or application SID to control call behavior. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"twilio": {
"url": "https://gateway.pipeworx.io/twilio/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/twilio/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Twilio data" })
The gateway picks the right tool and fills the arguments automatically.
