EpicTexting: Send SMS from Your AI Agent (Twilio)

Let your AI agent send text messages from your own Twilio number: one SMS or a personalised bulk text to up to 50 people, with delivery status.

EpicTexting

Your agent sends the text. EpicTexting sends SMS from your own Twilio number: one message or a personalised bulk text, with delivery status and replies.

1. Connect (once)

EpicTexting runs as a hosted MCP server: https://www.epictexting.app/api/mcp/mcp (Streamable HTTP, OAuth sign-in, no API key). If you already see EpicTexting tools (get_account_status, get_message_status …, possibly prefixed like mcp__epictexting__…), skip this. Otherwise tell the user the one command for their agent, then ask them to sign in when the browser opens:

Agent	Connect
Claude Code	claude mcp add --transport http epictexting https://www.epictexting.app/api/mcp/mcp then /mcp → epictexting → Authenticate

2. Tools

Tool	What it does	Kind
get_account_status	Twilio connected?, default sender, plan, SMS left this month	read-only
list_sender_numbers	Twilio numbers you can send from	read-only
send_sms	Send one SMS	sends / acts
send_bulk_sms	Send the same SMS to up to 50 people, personalised with {name}	sends / acts
list_recent_messages	Recent sent and received SMS	read-only
get_message_status	Delivery status of one message by SID	read-only

3. Rules (non-negotiable)

• Always confirm before sending. Show the user exactly who gets what text (every number and the final message, with {name} filled in for one example), and for bulk sends the count of SMS. Wait for a clear yes. One send per yes.
• Numbers must be international format ([phone], [phone]).
• Only text people who expect to hear from the user. No spam, no purchased lists, no marketing to people who haven't opted in. Respect STOP replies.
• If a result has connect_url, Twilio isn't connected: give the user that link and stop. If it has upgrade_url, the monthly limit is reached: share it.

4. Workflow

1. get_account_status first. If it returns connect_url, share it and stop.
2. Draft the message (and the recipient list for bulk). Use {name} for personalisation in send_bulk_sms.
3. Show the draft and get a yes. Then send_sms (one) or send_bulk_sms (≤50).
4. Report what was sent. If asked, check get_message_status with the returned SID, or list_recent_messages for replies.

5. Examples

1. "Text [phone]: running 10 minutes late, see you at 6:10." → Show number + text → yes → send_sms → "Sent from your default number."
2. "Send this to my 12 workshop attendees: Hi {name}, tomorrow's session starts at 10am in Room B." → Show list + one filled example + "12 SMS" → yes → send_bulk_sms.
3. "Did my last text to Priya get delivered?" → list_recent_messages to her number → get_message_status → delivered / failed with reason.
4. "Which numbers can I send from?" → list_sender_numbers.
5. "Any replies today?" → list_recent_messages → summarise inbound texts.

6. Errors

Result	Do this
401 / "sign in" / auth error	The MCP isn't authorised: run the connect step for the user's agent again.
connect_url / upgrade_url in a result	Give the user that link; don't retry.
Tool refuses the request	Explain the reason it gave; don't rephrase to get around it.
