# librarian
Librarian is a MCP (Model Context Protocol) Server that allows any LLM with a compatible MCP client to query Wikipedia for information. It can be configured to automatically fact-check information without requiring explicit user requests.
> *"The only thing that you absolutely have to know is the location of the library."*
>
> — Albert Einstein
*Example of Claude Desktop using the librarian MCP server to fact-check information*
