Short answer

How can I throttle message delivery with my AI?

Your AI uses QStash flow control keys to adjust parallelism and pause or resume message streams. This prevents your downstream services from being overwhelmed by sudden spikes in traffic.

Flow control outcomes

Manage your message pressure.

The AI acts as a buffer between your triggers and your infrastructure.

STABILITY

Protect downstream services

The AI adjusts flow control settings to ensure your databases or APIs don't crash under heavy load.

CONTROL

Pause and resume streams

Your agent can stop message delivery entirely or restart it once your services are ready to handle the volume.

VISIBILITY

Monitor active keys

The AI identifies which flow control keys are currently managing your message queues.

HUMAN

Manual intervention

You decide when to pin specific keys or change high-level logic that the AI shouldn't touch.

The workflow

What your AI does when <the thing arrives>.

The AI manages the pressure on your infrastructure through these moves.

  1. Identify flow controls

    The AI looks up existing flow control keys to see how your current message streams are being managed.

    list_flow_control_keys

  2. Inspect specific keys

    It checks the settings of a single key to understand its current parallelism or limits.

    get_flow_control_key

  3. Adjust delivery speed

    The AI pauses or resumes the flow to stop or start the message movement immediately.

    pause_flow_controlresume_flow_control

  4. Lock settings

    The AI can pin or unpin keys to ensure certain flow settings remain stable during operations.

FAQ

How this task behaves.

  • 01

    Can the AI delete my flow control keys?

    No. The AI can only list, get, pause, resume, pin, or unpin keys.

  • 02

    Can the AI change the actual message content?

    No. This MCP only manages the flow control settings, not the data inside the messages.

  • 03

    How does the AI know when to pause delivery?

    The AI pauses delivery based on the specific instructions or conditions you provide in your chat.

  • 04

    Can the AI create new flow control keys?

    No. The available tools are limited to managing existing keys.

  • 05

    Does the AI handle the actual message sending?

    No. QStash handles the delivery; the AI simply manages the flow control settings that govern that delivery.
