Twilio MCP

# twilio-mcp Simple MCP server for sending SMS via Twilio. Pure TypeScript, no build step. > **Why this exists:** The [official Twilio MCP](https://github.com/twilio-labs/mcp) has a [bug](https://github.com/twilio-labs/mcp/issues/42) that causes invalid tool schemas, making it unusable with Claude. This is a minimal alternative that just works. ## Usage ``` npx tsx src/index.ts --account-sid <sid> --auth-token <token> --messaging-service-sid <sid> [--default-to <number>] ``` ### Arguments - `--account-sid` - Twilio Account SID (required) - `--auth-token` - Twilio Auth Token (required) - `--messaging-service-sid` - Twilio Messaging Service SID (required) - `--default-to` - Default recipient phone number (optional) ## Claude Code Configuration Add to `~/.claude/settings.json`: ```json { "mcpServers": { "twilio": { "command": "npx", "args": [ "tsx", "/path/to/twilio-mcp/src/index.ts", "--account-sid", "YOUR_ACCOUNT_SID", "--auth-token", "YOUR_AUTH_TOKEN", "--messaging-service-sid", "YOUR_MESSAGING_SERVICE_SID", "--default-to", "+1987654321" ] } } } ``` ## Tools ### send_text Send an SMS message. **Parameters:** - `to` (optional if `--default-to` is set) - Recipient phone number in E.164 format - `message` (required) - The text message to send
