Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_subscribersA | Query the active SMS subscriber list to retrieve subscriber IDs and phone numbers. Useful for downstream targeting decisions. |
| get_keyword_idA | Look up all SMS opt-in keywords configured in the Postscript account. Returns each keyword's ID and reply message. Use the returned ID when calling add_subscriber so the new subscriber is tied to a documented consent flow. |
| add_subscriberA | Add a new phone number to the SMS list using a specific keyword ID. The keyword_id ties the subscription to an existing documented consent flow (required for TCPA/CTIA compliance). Returns the created subscriber. |
| list_campaignsA | Retrieve recent SMS marketing campaigns and their deployment status. Useful for an AI agent to check what has already been sent before drafting a new one. |
| check_segment_sizeA | Look up audience segments to see how many subscribers each contains. Use BEFORE drafting an SMS blast so the agent can scope the campaign correctly. |
