- FROM_NUMBER: Your Twilio phone number (in E.164 format, e.g., +11234567890)
To use this server with Claude Desktop, add the following to your configuration file:
macOS:~/Library/Application Support/Claude/claude_desktop_config.json
Windows:%APPDATA%\Claude\claude_desktop_config.json
{ "mcpServers": { "twilio": { "command": "npx", "args": [ "-y", "@yiyang.1i/sms-mcp-server" ], "env": { "ACCOUNT_SID": "your_account_sid", "AUTH_TOKEN": "your_auth_token", "FROM_NUMBER": "your_twilio_number" } } } }
After that, restart Claude Desktop to reload the configuration. If connected, you should see Twilio under the 🔨 menu.
Here are some natural ways to interact with the server through Claude:
Send a text message to the number +11234567890 saying "Don't forget about dinner tonight!"
Write a haiku about autumn and send it to my number +11234567890
- Phone Number Format: All phone numbers must be in E.164 format (e.g., +11234567890)
- Rate Limits: Be aware of your Twilio account's rate limits and pricing
- Security: Keep your Twilio credentials secure and never commit them to version control
-
"Phone number must be in E.164 format"
- Make sure the phone number starts with "+" and the country code
