Automatic WAF Rule Creation from Linear

Define a firewall rule in a Linear comment. Notis creates the WAF list in Cloudflare. No context-switching, no manual rule entry.

Trigger

Comment Received Trigger

Triggered when a comment is received.

Action

Create WAF List

Tool to create a new empty waf list for the account. use after confirming the account id. example: create list(account id="<id>", kind="ip", name="blocklist")

Why this helps

Firewall rule definitions happen in Linear or Slack, but then require manual entry into Cloudflare WAF. Errors and delays happen in the handoff.

  • Rules are defined once in Linear and automatically applied in Cloudflare
  • No manual Cloudflare WAF configuration
  • Clear audit trail of who defined what rule and when
  • Faster policy deployment

Setup

Build it in a few focused steps.

  • 1Connect Linear and Cloudflare to Notis.
  • 2Tell Notis: 'When a comment is posted on an issue labeled firewall-rule, create a WAF list in Cloudflare with the details from the comment.' Use Comment Received as the trigger.
  • 3Create and use a 'firewall-rule' label for firewall rule issues.
  • 4Test by commenting a firewall rule definition in an issue and confirming Notis creates the WAF list.

Questions about this workflow

What format should the firewall rule be in?

You define the format during setup. For example: 'Create a WAF list from IPs listed as Block: [IP] in the comment.'

Can I define multiple rules in one comment?

Yes. Tell Notis: 'Create a separate WAF list for each line starting with Rule: .'

Can I edit or update a rule after it's created?

Use a separate automation to update the WAF list when the Linear issue is updated.
