Mintlify static IP for Git provider allowlists

If your Git provider sits behind an IP allowlist or firewall, you need to allow the connections Mintlify makes to it. Mintlify’s platform connects to Git providers over HTTPS (port 443) from a single static egress IP address:

54.242.90.151

Add this IP address to your allowlist when:

• Your GitHub Enterprise Cloud organization has an IP allowlist enabled. See GitHub Enterprise with IP allowlists.
• A firewall or IP allowlist restricts inbound access to your GitHub Enterprise Server instance. See the GHES network requirements.
• A firewall or IP allowlist restricts inbound access to your self-hosted GitLab instance. See the self-hosted GitLab network requirements.

Agent and automation runs

Agent runs clone and push from separate sandbox infrastructure. That traffic uses dynamic IP addresses by default, so allowlisting 54.242.90.151 does not cover it. Mintlify support can route a deployment’s agent Git traffic through the static IP on request. See Fix agent runs blocked by an IP allow list.

Traffic from your Git server to Mintlify

Traffic in the other direction works differently. Your instance delivers webhook events to Mintlify hostnames such as leaves.mintlify.com and app.mintlify.com. Allow that outbound traffic by hostname. Mintlify does not publish a static IP address list for those endpoints, and their underlying IP addresses can change.
