Tools (5)

create_queue
Provision a new message queue. Returns queue_id, push_token, and poll_token. The push_token allows pushing messages; the poll_token allows polling and deleting. Store these securely.
push_message
Push a message to a queue. Requires the push_token for that queue. Message TTL is 24 hours. Limit: 1000 messages/queue/day.
poll_messages
Retrieve pending messages from your queue. Returns all messages not yet deleted, ordered oldest-first. Messages are NOT auto-deleted on poll — call delete_message after processing.
delete_message
Acknowledge and delete a message after processing. Required to prevent redelivery.
queue_info
Get stats for a queue: current depth, messages sent today, and rate limit status.
