How it runs

The automated pipeline, trigger to output.

  • TriggerDiscord webhook post receivedHTTP webhook
  • ActionLoad webhook history and baseline from PostgresPostgreSQLPostgres
  • LogicScore event for anomaly vs baseline
  • ActionRecord event to update baseline in PostgresPostgreSQLPostgres
  • OutputAlert security channel in Slack if anomalousSlack

What it does

Watches the traffic flowing through your Discord webhooks in real time. When a webhook starts firing far more often than its baseline, posts during unusual hours, or carries content patterns typical of spam takeovers, the flow treats the webhook as likely compromised and alerts your security team.

When to use it

Use it when legitimate webhooks (CI, alerts, bots) post to Discord on predictable cadences and a sudden flood means the token leaked. This catches abuse the moment it starts rather than after members report spam.

How it works

  1. 1An incoming webhook event delivers each Discord webhook post to the flow.
  2. 2A Postgres lookup pulls the recent send history and learned baseline for that webhook ID.
  3. 3A logic step scores the event against baseline — rate spike, off-hours timing, or suspicious payload — and decides if it crosses the anomaly threshold.
  4. 4Below threshold, the event is just recorded back to Postgres to update the baseline.
  5. 5Above threshold, a Slack alert goes to the security channel with the webhook ID, the trigger reason, and a one-click revoke link.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect HTTP webhookTrigger any URL on agent actions.
  2. 2
    Connect PostgresAny Postgres URL — query, write, migrate.
  3. 3
    Connect SlackChannels, DMs, threads, mentions.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
