Missing anthropic base url override in cursor (byok)

hi all,

i’m using bring your own key with Cursor and Anthropic models (claude). in my setup, i need to route requests through an internal proxy endpoint instead of hitting the default anthropic api directly.

what i expected
similar to the existing “override openai base url” setting, i expected a way to override the anthropic base url so requests can be redirected to a custom endpoint.

what actually happens
there is no “override anthropic base url” option. when using an anthropic api key, requests are always sent to the default endpoint:

  • https://api.anthropic.com

there’s no user-facing way to point this to something like:

  • https://<custom-proxy>/anthropic

impact
this blocks setups where:

  • companies require routing ai traffic through internal gateways

  • logging, caching, or policy enforcement happens at proxy level

  • custom infra wraps anthropic apis

question / ask
is there:

  1. any hidden / unofficial way to override the anthropic base url?

  2. plans to support this (similar to openai override)?

this feels like a pretty fundamental gap for teams using byok in controlled environments.
