What it does

An MCP server that wraps the Korean public library information API (도서관 정보나루) to expose 27 tools for searching libraries, books, availability, popularity trends, and statistics. It is intended for developers or AI assistants that need to query South Korean public library data programmatically.

• Search for public libraries near a given coordinate or in a specific region, then check whether a particular book is available for loan.
• Look up popular or trending books borrowed nationwide or by region, filtered by age group or library.
• Retrieve loan and return usage statistics or reading quantity data broken down by library or region.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
