Cernion Energy Tools MCP server

Cernion Energy Tools is the official remote MCP server from cernion.de. It answers at https://api.cernion.de/api/mcp over streamable HTTP and asks you to sign in with your cernion.de account before it lists its tools, so your client opens a login the first time it connects. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, got the sign-in challenge, so it is up.

Energy-domain MCP tools for Cernion context, evidence and guarded process preparation

Description as the publisher wrote it.

What Cernion Energy Tools 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 cernion.de account, and the tools appear once you have approved it.
