Twilio MCP: Documentation
Updated:
Connection
Repo: github.com/twilio-labs/mcp (108★, official Twilio Labs). Install: npx -y @twilio-alpha/mcp (stdio). Auth: TWILIO_ACCOUNT_SID + TWILIO_API_KEY/TWILIO_API_SECRET (Console → Account → API keys & tokens) — a dedicated API Key is recommended over the account's main auth token.
Tools
Tools are generated from Twilio's OpenAPI schemas across 1,400+ endpoints: messaging (SMS/WhatsApp — messages_create, messages_list), voice (calls, conferences, IVR), phone number verification (Verify API — create and check a code), phone numbers, billing and account settings. You can narrow the set with a --services flag at startup (e.g. Messaging and Verify only).
Agent flow
"Send a verification SMS via Verify to this number", "message the customer on WhatsApp with the tracking link", "call and play a voice message through an IVR flow".
Pricing
Twilio is pay-as-you-go: SMS from fractions of a cent per message, calls billed by destination, Verify billed per successful check. The MCP server itself is free — you pay for Twilio API usage.
Note
An official Twilio Labs project, but proof-of-concept status — the tool interface may change between versions; test before relying on it for critical production flows.
