Managing Subscriptions

Managing subscriptions

Subscriptions deliver product data on a fixed schedule. They support insight snapshots, dashboard snapshots, and AI prompt reports.

Read the relevant references

• Read subscription-types.md before you select or change a resource type.

• Read destinations.md before you create or change a destination.

• Read operations.md for schedules, limits, billing, delivery checks, and failures.

• Use creating-ai-subscription for the detailed prompt report creation workflow.

Choose the correct product

• Use a subscription for fixed delivery, such as "send this dashboard every Monday."

• Use a product alert for a condition, such as "notify me when conversion falls below 10%."

• Use a reminder when the user wants a private prompt to inspect a resource later.

• Use a Signals scout when an agent must decide what is important to report.

Subscriptions do not evaluate thresholds, recovery, consecutive breaches, or quiet hours. Snapshot subscriptions attempt each scheduled occurrence even when the saved results do not change.

Tools

Create a subscription

1. Call posthog:subscriptions-list and check for a duplicate.

2. Select one resource type from subscription-types.md.

3. Resolve the destination with destinations.md.

4. Resolve the schedule with operations.md.

5. Ask whether the user wants an immediate delivery.

6. Set send_test_now to the user's choice.

7. Call posthog:subscriptions-create.

8. Read the saved subscription and check each requested field.

9. If the user approved an immediate delivery, check its delivery record.

If creation times out or returns an uncertain result, list matching subscriptions before you retry. Creation is not idempotent. A blind retry can create a duplicate subscription and send a duplicate immediate delivery.

Do not infer missing recipients, channels, times, or time zones. Ask for these values before creation.

Find existing subscriptions

Use these list filters when they reduce ambiguity:

• resource_type: insight, dashboard, or ai_prompt.

• target_type: email, slack, or teams.

• insight or insights: One insight ID or a comma-separated ID list.

• dashboard: One dashboard ID.

• dashboard_tiles: Insight subscriptions for live tiles on one dashboard.

• created_by: One creator UUID.

Check for duplicates

Use search when the user supplied a title, insight name, dashboard name, or prompt text. Prompt subscriptions match their title and prompt text. Compare the resource, destination type, target, schedule, and enabled state.

A Teams result contains only the webhook host. One host can serve many channels. Do not use the host to identify a duplicate.

Show the title, schedule, creator, and creation date for possible Teams matches. Ask the user to select a subscription when these fields identify it. Create a new subscription when no field identifies the target channel.

Confirm the saved result

Check these fields after creation:

• resource_type matches insight, dashboard, or ai_prompt.

• target_type and the safe target label match the request.

• enabled is true.

• next_delivery_date matches the schedule and time zone.

• The AI and delivery options match the user's choices.

Change a subscription

Call posthog:subscriptions-retrieve before each update. Before an update that can send a delivery, list the current delivery IDs. Then call posthog:subscriptions-partial-update with the changed fields.

Ask before an update that can send an immediate delivery. The MCP update tool cannot suppress an immediate delivery for these changes. If the user does not approve delivery, do not make the update.

• Set enabled: false to pause delivery.

• Set enabled: true to resume delivery.

• Send the complete new target when you change recipients.

• Send target_type and target_value together when you change the destination type.

• Omit target_value to keep a saved Teams webhook URL.

• Send the full new Teams webhook URL when you replace it.

The resource type cannot change. Create a new subscription when the user wants a different resource type.

Check the new next_delivery_date after a schedule update. An exhausted schedule cannot resume until the user extends or removes its end condition.

After an update that sends a delivery, poll for a new target_change delivery ID. Read that delivery until it reaches a final state. Then retrieve the subscription and check its final enabled value.

Test and inspect delivery

1. Ask for approval unless the user already requested a test.

2. List the current delivery IDs.

3. Call posthog:subscriptions-test-delivery-create.

4. Poll for a new manual delivery ID.

5. Read the new delivery when the list result needs more detail.

Wait between polls and stop after two minutes. If delivery does not reach a final state, report the last state and suggest another check later.

A test sends a real message. The tool returns 202 after it queues the delivery. It returns 409 when another test is active or the subscription is disabled.

Delivery states are starting, completed, failed, and skipped. Filter the delivery list by status when you investigate a failure. A queued workflow does not prove delivery. A completed delivery can contain partial recipient failures. The MCP tools hide per-recipient results. Do not claim that each recipient succeeded.

Stop a subscription

Confirm the subscription ID and safe destination label. Ask for approval unless the user already requested deletion or unsubscribe. Then call posthog:subscriptions-delete.

Deletion is a one-way soft delete through MCP. It stops future deliveries and frees a plan slot. Create a new subscription if the user needs it again.

Report the result

• State the resource type, destination type, schedule, and next delivery date.

• State whether the subscription is enabled.

• State whether AI features can consume AI credits.

• Do not repeat email addresses unless the user needs them for confirmation.

• Never repeat a Teams webhook URL.
