# developers.openai.com

OpenAI hosts documentation for its tools and APIs on this site.

Run by OpenAI · Ports: 443 TCP · Checked: 3 November 2026

## Short answer

OpenAI’s developer documentation site and read-only documentation MCP endpoint.

Block with care

Blocking this host can interrupt OpenAI tools that depend on it.

Matches

`developers.openai.com`

A name with `*.` covers every name under it: `*.push.apple.com` matches `1-courier.push.apple.com`.

## What it serves

The documentation MCP endpoint lets compatible clients search OpenAI documentation without making API calls on your behalf.

A configured application or AI tool can connect here when you use the relevant integration.

A hostname identifies the destination, not the content of encrypted requests.

A connection alone does not establish which account permissions were granted or what actions were taken.

## What breaks if you block it

Block with care

Blocking this host can interrupt OpenAI tools that depend on it.

What breaks if you block it

- Integrations or applications using developers.openai.com may fail to connect.
- Related workflows can stop until the connection is allowed again.

With Kilobat Pro and the network filter, you can block a host for every app or for one app: in Connections, select a connection and choose Block. Apple’s own services are never blocked by Kilobat’s [Protection](https://kilobat.app/docs/blocking#protection) lists.

## Notes

Other related services may use different hostnames. Blocking this address alone does not block every service from the provider.

If a connection is unexpected, inspect the originating process and the integrations you have enabled.
