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