Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The GitHub repo last changed –, and the latest version (1.11.3) reached the registry yesterday.

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 Bukku credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/bukku/
On first connect you will paste your Bukku access token and company subdomain. They are validated, stored per-user, and scoped to you. No keys in config files.
