Connect your Anthropic account
Outlet needs your Anthropic admin key, which is different from a regular API key. Outlet uses it to create a capped key for each app you approve, inside your own account. It is stored encrypted and never given to any app.
What you need
A Claude Console account that is part of an organization where you hold
the admin role. Individual accounts need to set up an organization first;
it takes a minute and you automatically become its admin. Admin keys start with
sk-ant-admin. Regular keys start with sk-ant-api and will
not work for connecting.
Steps
Sign in to the Claude Console
Go to platform.claude.com and sign in. Older links to console.anthropic.com land in the same place.
Set up your organization (skip if you have one)
Open Organization settings in the sidebar. If Anthropic asks you to create an organization, do it; solo accounts are fine, an organization of one is normal. Admin keys lives in the same section.

Create the admin key and copy it
Open Admin keys, or go straight to
platform.claude.com/settings/admin-keys.
Click Create admin key, name it Outlet, and copy the
sk-ant-admin... key right away. It is shown only once. If you lose
it, delete it there and make a new one. Anthropic's red warning on that page is
the point: this key runs your whole organization, so it goes into Outlet and
nowhere else.

Paste it into Outlet
Back in Outlet, paste the key when asked. Done. You can revoke it any time from the same page, which cuts Outlet off completely.
