More Details Connect to Claude

Connect your Upstash QStash account to any AI agent to orchestrate serverless messaging and background tasks through natural language.

What you can do

  • Message Publishing — Send messages to URLs or URL Groups with custom delays, retries, and deduplication via publish_message.
  • Queue Management — Create and manage FIFO queues with controlled parallelism for reliable task processing using upsert_queue and list_queues.
  • Scheduling — List, pause, and resume cron-based schedules for recurring background jobs with list_schedules.
  • DLQ Handling — Inspect and retry failed messages in the Dead Letter Queue to ensure no data loss using list_dlq and retry_dlq_message.
  • Flow Control — Monitor and adjust rate limits and parallelism across your messaging infrastructure with list_flow_control_keys.

How it works

  2. Enter your QStash Token from the Upstash Console

See how to talk to your AI agent using QStash (Serverless Message Queue).

Publish a POST request to https://api.example.com/webhook with a 1-hour delay.

I've published the message to your destination. It is scheduled for delivery in 1 hour. Message ID: msg_82391.

List all my current QStash queues and their status.

I found 3 queues: 'image-processing' (Active), 'email-service' (Paused), and 'webhooks-main' (Active).

Check the Dead Letter Queue and retry the message with ID msg_123.

I've located the message in the DLQ and successfully triggered a retry for msg_123.

Use the `publish_message` tool and provide the `delay` parameter (e.g., '10m' for 10 minutes) or a `not_before` Unix timestamp.
