Turns your letterhead PDF into a document processing service that Claude can call directly. Exposes operations for merging letterheads onto existing PDFs or converting Markdown documents into letterheaded PDFs with smart margin detection. The server analyzes your letterhead template to figure out printable areas, then renders Markdown with proper typography using Pango and Cairo. You'd reach for this if you're generating formal correspondence, reports, or proposals through Claude and need them to look professionally branded without manual formatting. Requires macOS and expects letterhead templates in ~/.letterhead/ along with optional CSS files for Markdown styling. Works through stdio transport with configurable output directories and letterhead styles.
