Can Claude merge PDFs?
Not on its own. a chat AI can't run programs or write files on your computer. With the GUI Hub Essentials MCP server installed, Claude (Desktop or Code), Cursor, VS Code and other MCP clients can merge PDF files locally: the assistant calls the pdfcpu_merge tool, which runs pdfcpu on your machine. Files are not uploaded.
