It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Papierkram credentials.

On first connect you'll enter your Papierkram account (the first part of https:// .papierkram.de) and an API token (create it under Einstellungen > API; the API is a beta feature of the plans M and L). They are validated, stored per-user, and scoped to you — no keys in config files.
