# merge_pdfs: Merge PDFs

Join PDFs into one, in the order given (file_ids, then files, then file_urls). Each part gets a bookmark with its name.

A tool of the [FynePDF MCP server](https://fynepdf.com/developers/docs/mcp) (`https://api.fynepdf.com/mcp`). Makes a new file; the original is kept.

## Ask for it
