Featured Twilio Tools

send-message: Send an SMS or MMS message to a phone number. Returns the message SID, status (queued), and price estimate. WHEN TO USE: User asks "send a text to +1234567890", "text John hello", "send an SMS", or "message this number". STEP-BY-STEP to send a message: 1. Use list-phone-numbers to find your Twilio phone number (this is the "from" number). 2. Use send-message with to (recipient), from (your Twilio number), and body (text). 3. Optionally use get-message with the returned SID to check delivery status. CRITICAL — E.164 FORMAT REQUIRED for all phone numbers: WRONG: to="4155551234" — CORRECT: to="+14155551234". WRONG: from="(415) 555-1234" — CORRECT: from="+14155551234". CRITICAL — Trial accounts can ONLY send to verified phone numbers. If send fails with error 21608, the "to" number is not verified. SMS body max is 1,600 characters. Messages over 160 GSM-7 chars are split into multiple segments and billed per segment. EXAMPLE: to="+14155551234", from="+14155559876", body="Hello from Twilio!".

list-messages: List SMS and MMS messages sent and received. Returns message body, from/to numbers, status (queued/sending/sent/delivered/undelivered/failed/received), direction (inbound/outbound-api/outbound-reply), segment count, price, and timestamps. Results are sorted newest first. WHEN TO USE: User asks "show my recent messages", "what SMS did I send?", "list texts to +1234567890", "show failed messages", "what messages did I receive today?", or any question about message history. CRITICAL: Phone number filters must be in E.164 format. WRONG: to="4155551234" — CORRECT: to="+14155551234". EXAMPLES: Recent messages: no filters (returns newest 50). Messages to a number: to="+14155551234". Messages sent today: date_sent="2026-02-15". Messages in a date range: date_sent_after="2026-02-01", date_sent_before="2026-02-15". PAGINATION: Use next_page_uri from a previous response to get the next page of results.

list-calls: List voice calls made and received. Returns from/to numbers, status (queued/ringing/in-progress/completed/busy/failed/no-answer/canceled), direction (inbound/outbound-api/outbound-dial), duration in seconds, price, and timestamps. Newest first. WHEN TO USE: User asks "show my recent calls", "list calls to +1234567890", "show failed calls", "how many calls did I make this week?", "what calls came in today?", or any voice call history question. CRITICAL: Phone number filters must be E.164 format. WRONG: from="4155551234" — CORRECT: from="+14155551234". EXAMPLES: All recent calls: no filters (returns newest 50). Failed calls only: status="failed". Calls to a number: to="+14155551234". Calls this week: start_time_after="2026-02-10". Completed calls from a number: from="+14155551234", status="completed". PAGINATION: Use next_page_uri from a previous response to get the next page.

get-usage-records: Get usage and billing records for the account. Shows categories (calls, sms, recordings, phonenumbers, totalprice), usage amounts, counts, and costs. Use "period" to get daily, monthly, today, yesterday, this-month, or last-month summaries. Filter by category and date range.

list-phone-numbers: List Twilio phone numbers owned by this account. Returns phone numbers in E.164 format, friendly names, capabilities (voice, SMS, MMS, fax), and configured webhook URLs for each number. IMPORTANT: This is a prerequisite tool — call it BEFORE send-message to find your "from" number. WHEN TO USE: User asks "what phone numbers do I have?", "show my Twilio numbers", "which numbers can send SMS?", "what is my Twilio number?", or BEFORE sending any message (to get the from number). STEP-BY-STEP to send a message: 1. list-phone-numbers to find your Twilio number. 2. Check the "capabilities" field to confirm the number supports SMS. 3. Use that number as the "from" in send-message. EXAMPLES: All numbers: no filters. Find specific number: phone_number="+14155551234". Search by name: friendly_name="Marketing".

get-account: Get information about the Twilio account. Returns account name, status (active/suspended/closed), type (Trial/Full), SID, and creation date. Use this as your FIRST tool to verify connectivity and confirm the account is active before performing other operations. WHEN TO USE: User asks "is my Twilio account active?", "what type of Twilio account do I have?", "show my account info", "am I on a trial account?", or when you need to verify the API key works. IMPORTANT: If status is "suspended" or "closed", no other tools will work. If type is "Trial", the account can only send messages to verified phone numbers.
