What it saves

The same four files were placed in two sessions and the same task sentence was handed to the same model. One side could only use this server. The other had no dedicated tools and was free to use the shell and Node.

	Without tools	With ezpzfile-mcp
Cost	$0.28	$0.13
Wall time	9:06	0:39
Tasks finished	2 / 4	4 / 4
Tool calls	20	10
Tokens	510,607	184,605

That is 53% less cost and 93% less time. Tokens and cost are not estimates; they are the per-message figures the sessions recorded, added up. Measured 2026-09-12.

The bare session never started two of the tasks. It spent the clock hunting for and installing libraries for the two Korean documents. Read the gap as a floor, not a ceiling: had it been made to finish all 4, the difference would be wider.

The tools

Six of them, not twenty five. Tool definitions sit in the model's context for every conversation, so related jobs share one tool and an argument picks between them. mcp/README.md has the full list and every argument.

Tool	What it does
doc_read	Text out of DOCX, PDF, HWP, HWPX and EML, tables included
doc_convert	Documents to PDF, PDF pages to images, sheets to CSV or JSON, Korean formats to each other
pdf_edit	Merge, extract, delete, rotate, reorder, split, compress, protect, unlock
pdf_info	Page count, page sizes, encryption, metadata
image_edit	Resize, compress, convert, strip EXIF and GPS, cut out the background
qr_make	A link or some text as a PNG or SVG

Layout

Path	What it is
mcp/	The package: server, tools, build

sharp and @napi-rs/canvas are native, so they are built for your platform on install. Background removal downloads a 4.4MB model and a 14MB runtime the first time you ask for a cut-out, then caches them under ~/.cache/ezpzfile-mcp. That is the only thing here that touches the network, and it uploads nothing.
