Connect Twilio to Claude Code

Let Claude send messages and manage numbers in Twilio. From the terminal, inside the sessions where you already work.

How do you connect Twilio to Claude Code?

Claude Code reaches outside tools through MCP servers. To connect Twilio, you add a Twilio MCP server: a small hosted service that exposes Twilio's data and actions over the Model Context Protocol. With a custom connector we build for you, that is one command in the terminal, then an OAuth sign-in with your own Twilio account. No API keys pasted into config files.

claude mcp add --transport http twilio https://your-connector-url/mcp

Then run /mcp inside a Claude Code session to sign in. Add it with --scope project and the connector is checked into the repo for your whole team.

What can Claude Code do in Twilio once connected?

Full read-write Twilio access lets Claude send an SMS or WhatsApp message, buy or release a phone number, update a messaging service, configure a webhook, and trigger an outbound call, all once you approve. The work that used to mean console clicks or one-off scripts happens where the conversation already is.

Send an SMS or WhatsApp message to a recipient after you approve it
Search for and purchase a new phone number in a given area code
Add or remove numbers from a messaging service or sender pool
Update a phone number's voice and messaging webhook URLs
Trigger an outbound call from a configured Twilio number
Release a phone number you no longer need

One connector, every Claude surface

The connector we build is a remote MCP server, which is the same standard claude.ai and Claude Desktop use. Add it once and the same Twilio access works in Claude Code for you, in claude.ai for the rest of the team, and in Claude Desktop. One build, one set of permissions, one monthly plan covering all of them.

Build it yourself, or have it built?

If you live in the terminal, you can absolutely write your own MCP server against the Twilio API. The protocol is open. What you take on is everything around the happy path: OAuth token refresh, hosting, monitoring, keeping up when Twilio changes its API and when the MCP spec itself moves, and scoping write actions so an agent can never do more than you intended. We build Twilio connectors with separated read and write tools and approval gates on destructive actions, then host and maintain them so they keep working while you work.

Frequently asked questions

Does the same Twilio connector work in claude.ai and Claude Code?

Yes. It is one remote MCP server. Claude Code adds it with a single "claude mcp add" command; claude.ai and Claude Desktop add it as a custom connector in Settings. Each person signs in with their own Twilio account, so access always matches what that person can already see and do.

Do I need to host or maintain anything myself?

No. The connector runs as a hosted service we operate: we handle uptime, token health, API changes on Twilio's side, and MCP spec migrations under the monthly plan. Your side is one command in the terminal and an OAuth sign-in.

Is it safe to give a coding agent write access to Twilio?

Write access is scoped, not blanket. Read tools and write tools are separated, destructive actions like deleting or sending are gated behind your explicit approval, and the connector can never exceed the permissions of the Twilio account it signs in with. Revoking access is one click in Twilio.
