ezpzfile/ezpzfile-mcp

File tools for AI agents. Read and convert documents (DOCX, PDF, HWP, HWPX, EML, and
Japanese JTD and XDW), turn PDFs back into Word, Excel or HWP, edit PDFs, resize and
clean images, cut out backgrounds, make QR codes. Everything runs on your machine and
no file is ever uploaded.

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, EML, JTD and XDW, tables included, or what a file records about itself |

| pdf_edit | Merge, extract, delete, rotate, reorder, split, compress, protect, unlock, replace text |
