What it does

Reviews every GitLab merge request for hardcoded credentials before merge. If a secret is found it fails the MR check to block the merge, and if that secret has already been pushed to a remote branch it treats the leak as live, rotating the Vercel environment value and opening a tracked remediation task.

When to use it

Use this on GitLab teams that gate merges with checks and want prevention plus response in one flow. It stops new leaks at review time while still rotating anything that already touched a remote, so a blocked MR never leaves a live exposed key behind.

How it works

  1. 1A GitLab merge request event fires with the diff and source branch.
  2. 2A scan step checks the changes for credential signatures.
  3. 3A branch routes clean MRs to a pass and flagged MRs onward.
  4. 4The MR check is set to failed so the merge is blocked.
  5. 5A second branch tests whether the secret already exists on a pushed remote branch.
  6. 6If so, Vercel rotates the affected value and revokes the old key.
  7. 7A ClickUp task is created with the MR link, author, and rotation outcome.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect GitLabRepos, MRs, pipelines, registry.
  2. 2
    Connect VercelDeploys, runtime logs, analytics.
  3. 3
    Connect ClickUpDocs + tasks + chats in one workspace.
  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.
