Capabilities

Tools 25

add_recipient

Add another person who can receive reminder calls, e.g. an elderly parent. ReminderIt immediately places a consent verification call to the number; reminders are only delivered after that person accepts. Only add someone the user genuinely has permission to call, and confirm the number digit by digit before submitting — a typo calls a stranger. Args: name: The person's name, used in the call greeting. phone: Their number in full E.164 format, e.g. "+447700900123". relationship: Optional label for the user's own reference, e.g. "Mother".

Discovered
clear_reminder_voice

Remove a reminder's custom voice so it uses the account default again. Args: reminder_id: Reminder whose voice override should be cleared.

Discovered
create_reminder

Schedule a new reminder phone call. This places REAL calls, so get the schedule right the first time: resolve the timezone via whoami, and read the result back to the user afterwards. Provide exactly one schedule: run_at (one-off), cron_expr, or interval_days. Leave the voice arguments empty to use the account's default voice. Args: title: Short label shown in the app, e.g. "Morning pills" (max 120 chars). message_text: Exactly what the voice says on the call, written as speech — "Time to take your blood pressure tablet." (max 600 chars). Avoid abbreviations and symbols that sound wrong when read aloud. type: "once" for a single call, "recurring" for a repeating schedule. timezone: IANA timezone the schedule is anchored to, e.g. "America/New_York". run_at: ISO 8601 local datetime for a one-off call. Required when type="once". cron_expr: Cron schedule for recurring calls, e.g. "0 8 * * 1-5" = weekdays 8am. interval_days: Repeat every N days (1-365). Simpler alternative to cron_expr. start_date: ISO date; the recurring series does not fire before this. end_date: ISO date; the series stops after this (e.g. end of a medication course). skip_dates: Local dates to skip, ["2026-08-12"] format — holidays, travel. recipient_id: Call a care-recipient (from list_recipients) instead of the account owner. The recipient must have consented. voice_id: Override the account voice for this reminder only (see list_voices). personality: Speaking style — "gentle", "cheerful", "professional", "energetic". language: BCP-47 language tag for the spoken message, e.g. "en-GB", "hi-IN". speaking_rate: Speech speed, 0.8 (slower) to 1.2 (faster). 1.0 is normal. whatsapp_fallback: Send the reminder on WhatsApp if the call isn't answered. email_fallback: Also email the reminder if the call isn't answered.

Discovered
delete_reminder

Permanently delete a reminder. This cannot be undone. Confirm with the user first, quoting the reminder's title and schedule. If they may want it later, use pause_reminder instead. Args: reminder_id: Reminder to delete (from list_reminders).

Discovered
get_recent_calls

Show recent delivery history — what was actually called, sent, or missed. Use this to answer "did it call me?", "why didn't I get it?", or to confirm a reminder is really firing. Statuses: completed/answered = the person picked up; no-answer/busy = rang but nobody answered (a WhatsApp fallback usually follows); failed = the call could not be placed; blocked = suppressed before dialling (no credit, unsupported country, or a recipient who hasn't consented); sent/delivered/read = a WhatsApp or email fallback. Args: limit: Number of recent delivery records (1-50, default 10).

Discovered
get_reminder

Get the full configuration of one reminder as JSON. Use when you need detail that list_reminders omits — the exact spoken message, cron expression, skip dates, channel toggles, or voice override. Also use this to read current values before a partial update, so you don't overwrite settings. Args: reminder_id: Reminder ID from list_reminders.

Discovered
get_usage

Get remaining call quota, calls used, plan, and the current billing period. Check before creating several reminders or suggesting a test call, and whenever a delivery fails unexpectedly. One call OR one WhatsApp fallback each consume one unit from the same pool. When the balance is low or zero, tell the user plainly.

Discovered
get_voice_settings

Show the account's default voice — the voice every reminder uses unless overridden. Read this before changing anything, so you can report what actually changed and leave unrelated settings alone.

Discovered
list_recipients

List care-recipients — other people this account can send reminders to. Needed to get the recipient_id for create_reminder. Consent status matters: only "confirmed" recipients receive calls; "pending" means they haven't accepted the verification call yet, so reminders to them will be blocked.

Discovered
list_reminders

List every reminder on the account with its schedule, state and next call time. Start here for almost any request about existing reminders — it is the only way to discover reminder IDs, which every other reminder tool needs. Paused reminders show WHY they are paused (out_of_credit, destination_not_allowed, completed).

Discovered
list_upcoming

Show the next scheduled calls across ALL reminders, in chronological order. Answers "what's coming up?" better than list_reminders, because it expands recurring rules into actual upcoming occurrences and merges them into one timeline. Args: limit: How many upcoming occurrences to return (1-50, default 10).

Discovered
list_voices

List the voices available on this account, with language, accent and tier. Call before set_voice_settings or set_reminder_voice to get valid voice IDs — never guess one. Voices marked premium may not be included in every plan; if the account's plan doesn't include one, calls fall back to a standard voice.

Discovered
pause_reminder

Pause a reminder so it stops calling, keeping all its settings intact. Prefer this over delete_reminder whenever the user might want it back — it is fully reversible with resume_reminder. Args: reminder_id: Reminder to pause (from list_reminders).

Discovered
preview_voice

Generate a short audio sample of a voice so the user can hear it before choosing. Returns a URL to the generated audio. Useful when a user is deciding between voices, or wants to check how their own reminder wording will sound. Args: voice_id: Voice ID from list_voices. text: Words to speak in the sample. Defaults to a standard demo line; pass the user's actual reminder message to preview exactly what they'll hear. personality: "gentle", "cheerful", "professional", or "energetic". language: BCP-47 tag, e.g. "en-GB". speaking_rate: 0.8 to 1.2.

Discovered
remove_recipient

Remove a care-recipient from the account. Any reminders targeting them will stop being delivered. Confirm with the user first. Args: recipient_id: Recipient to remove (from list_recipients).

Discovered
resend_recipient_verification

Re-send the consent verification call to a recipient who hasn't confirmed yet. Use when list_recipients shows consent as pending and the person missed the first call. Don't repeat it more than necessary — each attempt rings their phone. Args: recipient_id: Recipient to re-verify (from list_recipients).

Discovered
resume_reminder

Resume a paused reminder so it starts calling on its schedule again. If it was paused automatically for out_of_credit and the account still has no calls left, it will pause again at the next occurrence — check get_usage and tell the user. Args: reminder_id: Reminder to resume (from list_reminders).

Discovered
set_reminder_channels

Choose what happens when a reminder call isn't answered. The phone call itself is always attempted. These toggles control the follow-ups: WhatsApp is on by default, email is off. Note each delivered fallback also consumes one call from the account's quota. Args: reminder_id: Reminder to configure (from list_reminders). whatsapp_fallback: True to send a WhatsApp message when the call is missed. email_fallback: True to also email the reminder when the call is missed.

Discovered
set_reminder_voice

Give one reminder its own voice, overriding the account default. Use when a specific reminder should sound different — a calm, slower voice for medication; an energetic one for a workout; a different language for a relative. Call list_voices first to get valid voice IDs, and preview_voice if the user wants to hear it before committing. Other reminders are unaffected. Args: reminder_id: Reminder to restyle (from list_reminders). voice_id: Voice ID from list_voices. personality: "gentle", "cheerful", "professional", or "energetic". language: BCP-47 tag for the spoken message, e.g. "en-GB", "es-ES", "hi-IN". speaking_rate: 0.8 (slower, good for elderly listeners) to 1.2 (faster).

Discovered
set_skip_dates

Set the specific dates a recurring reminder should NOT call. The right way to handle holidays, travel, or a pause of a few days — far better than deleting a reminder and rebuilding it. This REPLACES the existing skip list, so include dates the user still wants skipped (read them with get_reminder first). Pass an empty list to clear all skips. Args: reminder_id: Reminder to adjust (from list_reminders). skip_dates: Local dates in "YYYY-MM-DD" form, e.g. ["2026-08-12", "2026-08-13"].

Discovered
set_voice_settings

Change the account's DEFAULT voice, affecting every reminder without an override. For a single reminder only, use set_reminder_voice instead. Get valid IDs from list_voices; preview_voice lets the user hear one first. Args: voice_id: Voice ID from list_voices. personality: "gentle", "cheerful", "professional", or "energetic". language: BCP-47 tag, e.g. "en-US", "en-GB", "hi-IN". speaking_rate: 0.8 (slower — often better for elderly listeners) to 1.2 (faster). greet_by_name: Whether calls open by greeting the user by name.

Discovered
skip_next_occurrence

Skip only the next scheduled call, leaving the rest of the schedule untouched. Use for "not tomorrow, but keep it going after that". To skip particular calendar dates instead, use set_skip_dates. Args: reminder_id: Reminder whose next call should be skipped.

Discovered
test_call

Place an immediate test call for a reminder so the user can hear it right now. The phone will ring within seconds — only do this when the user has asked to test, and never repeatedly. It consumes one call from their quota and does not change the schedule. Args: reminder_id: Reminder to test (from list_reminders).

Discovered
update_reminder

Edit a reminder's wording or schedule. Only the fields you pass are changed. Use for "move it to 7am", "say it differently", "stop after the 20th". To pause or resume, use pause_reminder / resume_reminder. To change the voice, use set_reminder_voice. To skip particular dates, use set_skip_dates. Args: reminder_id: Reminder to edit (from list_reminders). title: New short label. message_text: New spoken message (written as natural speech, max 600 chars). cron_expr: New cron schedule, e.g. "0 7 * * *" for daily 7am. interval_days: New "every N days" interval (1-365). run_at: New ISO 8601 datetime for a one-off reminder. timezone: New IANA timezone. Changing this moves every future call. start_date: New ISO start date for a recurring series. end_date: New ISO end date; the series stops after it.

Discovered
whoami

Identify the connected ReminderIt account: who it is, their timezone, plan and quota. Two jobs. First, it is the connection check — call it when the user asks "am I connected?", "which account is this?", or when another tool returns an auth error, to confirm the API key is valid and see whose account it opens. Second, call it BEFORE creating or rescheduling a reminder: it returns the user's saved timezone, so you can schedule silently instead of asking. It also warns when the phone is unverified or the account is opted out — in either case no reminder can be delivered, so surface that before scheduling anything.
