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.

Operators can list their own server through the public API or the koskamo_register_mcp_server MCP tool: prove control of the endpoint's domain with a well-known file or a DNS TXT record, pass the live check, and it is published at once. Proofs are re-checked weekly. Admins can still hide or remove any listing.
