Unplain MCP server

Unplain is the official remote MCP server from unplain.io. It answers at https://app.unplain.io/api/mcp over streamable HTTP and asks you to sign in with your unplain.io 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 11 September 2026; the last check, on 24 October 2026, got the sign-in challenge, so it is up.

Your assistant writes the ebook or report; Unplain designs it and returns a publish-ready PDF.

Description as the publisher wrote it.

What Unplain 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 unplain.io account, and the tools appear once you have approved it.
