How listings and access work
Every listing passed a live check and is re-checked weekly. Servers that keep failing are hidden. Koskamo does not operate these servers; review their tools before connecting.
No sign-in servers work without an account. Optional OAuth servers prompt for sign-in only for account tools. Other servers require vendor sign-in or an API key, shown in each row.
