What it does

The server builds MCP tools from Twilio's OpenAPI specs: calls, messaging, phone numbers, Studio, Serverless, TaskRouter, Verify and other services. Because the API is huge, you pick the parts you need with --services or --tags, otherwise the tools will not fit the model context. The same monorepo ships a separate package that turns any OpenAPI spec into an MCP server. The project is marked as a proof of concept by the Twilio Alpha team.

Who it is for. For developers configuring telephony, SMS and Studio flows in Twilio.

Limitations

An experimental project with no guarantees. Requires a Twilio account with an API Key and Secret, and operations are billed. Twilio advises against running community MCP servers alongside it due to injection risk. Twilio services are restricted for Russia, so access without a VPN is not guaranteed.

How to disable. Remove the twilio block from the client's MCP config and revoke the API Key in the Twilio console.

README in short

The root README describes a monorepo with two packages: a server for all Twilio public APIs and a generic server for OpenAPI specs. It shows launching via npx with credentials in the argument and a warning about community MCP servers. The package README lists available services and tags with filtering examples. MIT licensed.
