Zerno Lite MCP server

Zerno Lite is the official remote MCP server from zerno.one. It answers at https://zerno.one/mcp over streamable HTTP and asks you to sign in with your zerno.one account before it lists its tools, so your client opens a login the first time it connects. Our probes reached it 6 of 7 times since 12 September 2026; the last check, on 12 November 2026, got the sign-in challenge, so it is up.

Description as the publisher wrote it.

What Zerno Lite needs before it works

A sign-in. The server refused to list its tools to an anonymous client and answered with an authentication challenge, which is how an MCP server protected by OAuth behaves. Add it with one of the setups below; the first connection opens a login for your zerno.one account, and the tools appear once you have approved it.
