Notifications

When an alert fires or resolves, MCPHub can send a notification to a Slack channel or any HTTP endpoint.

Slack webhook

1. In your Slack workspace, create an Incoming Webhook app and copy the webhook URL
2. When creating or editing an alert rule, paste the URL in the Slack webhook URL field
3. MCPHub will POST a message to the channel when the alert fires or resolves

Example Slack message:

🔴 FIRING — github-mcp error rate > 5%
Current value: 12.3%  |  Window: 30 min
MCPHub · github.com/your-org

Generic HTTP webhook

For PagerDuty, Opsgenie, custom alerting pipelines, or any other system:

1. Enter the webhook URL in the Webhook URL field
2. MCPHub will POST a JSON payload to that URL on every event

Payload format:

{
  "event": "FIRING",
  "rule_name": "High error rate",
  "server_id": "uuid",
  "server_name": "github-mcp",
  "metric": "error_rate",
  "threshold": 5,
  "current_value": 12.3,
  "fired_at": "2026-03-28T14:00:00Z"
}

No notification (dashboard only)

Leave both notification fields empty to still track alert events in MCPHub without external notifications. You can still review FIRING/RESOLVED events in the alert history.

Notification delivery

Notifications are fire-and-forget. If the webhook endpoint is unavailable, the delivery fails silently. The alert event is still recorded in MCPHub.
