31b8b2e6d4 docs: flag texlive-latex-extra requirement, recommend tectonic
Some checks are pending
Security Scan / security-scan (push) Waiting to run
texlive-xetex alone is rarely enough — pandoc's default template needs
packages from texlive-latex-extra (Debian) / texlive-latexextra (Arch):
lastpage, xcolor, framed, fancyhdr, etc. Real markdown docs fail with
"File 'X.sty' not found" without them.

Restructure system deps to present three engine routes per platform:
- tectonic (recommended): ~30 MB static binary, downloads packages on demand
- full TeX: texlive-xetex + texlive-latex-extra + texlive-fonts-extra
- weasyprint: skip TeX entirely, pip-installable

Add an engine comparison table in the README explaining the disk-size
and quality trade-offs so users can pick informed.

964fd14a26 docs: cover markdown_to_pdf, [markdown] extra, uvx + pacman install
README:
- bump tool count 46 → 47, add Format Conversion bullet
- fix `claude mcp add` syntax (needs `--` separator before uvx)
- show `uvx --from "mcp-pdf[markdown]" mcp-pdf` for the new tool
- note about uvx caching + `--refresh`
- new "Format Conversion" tools subsection (markdown_to_pdf alongside pdf_to_markdown)
- new "Optional Extras" section explaining [forms], [tables], [markdown], [all]
- expand System Dependencies with Arch (pacman) and macOS (brew) recipes for
  pandoc + a PDF engine

QUICKSTART:
- replace stale `mcp-pdf-tools` package name with current `mcp-pdf`
- add uvx as the recommended end-user install path
- add pip install patterns including all optional extras
- add pacman block alongside apt-get and brew
- add markdown_to_pdf troubleshooting (mktexfmt errors, engine fallback)
- add a smoke-test snippet using the new tool

## 1. Installation
### Option A: Using UV (Recommended for Development)
### Option A: Run from PyPI with uvx (Recommended for end users)
No clone required — `uvx` fetches and runs in an isolated cached venv:
```bash
# Bare install
uvx mcp-pdf
# With markdown_to_pdf support (requires pandoc on host)
uvx --from "mcp-pdf[markdown]" mcp-pdf
# Force a refresh after a new release
uvx --refresh --from "mcp-pdf[markdown]" mcp-pdf
```
### Option B: pip install from PyPI
```bash
pip install mcp-pdf
# Or with optional extras:
pip install "mcp-pdf[markdown]" # adds markdown_to_pdf
pip install "mcp-pdf[forms]" # adds form creation tools
pip install "mcp-pdf[tables]" # adds Camelot/Tabula table extraction
pip install "mcp-pdf[all]" # everything
```
### Option C: Local development with uv
```bash
# Clone the repository
git clone https://github.com/rpm/mcp-pdf-tools
cd mcp-pdf-tools
git clone https://github.com/rsp2k/mcp-pdf
cd mcp-pdf

## 2. System Dependencies
`uvx` and `pip` only handle Python deps. Some tools call out to system binaries that you'll need to install separately:
| Binary | Required for |
|--------|-------------|
| `tesseract` | `ocr_pdf` |
| `ghostscript` | Camelot table extraction |
| `java` (JRE) | Tabula table extraction |
| `poppler` | PDF→image conversion |
| `pandoc` | `markdown_to_pdf` |
| `xelatex` / `pdflatex` / `tectonic` / `weasyprint` / `wkhtmltopdf` | `markdown_to_pdf` (need at least one) |
> **Note on the LaTeX engine:** `texlive-xetex` alone is often not enough for real markdown docs — pandoc's default template needs LaTeX packages (`lastpage`, `xcolor`, `framed`, `fancyhdr`, etc.) that live in `texlive-latex-extra` (Debian) / `texlive-latexextra` (Arch). If you don't already use TeX, **`tectonic` is a much better choice** — it's a ~30 MB static binary that downloads packages on demand. See the README's "Picking a PDF engine" table for details.

## 3. Claude Desktop Configuration
## 3. Adding to Claude Code / Claude Desktop
Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:
### Easiest — `claude mcp add` with uvx
```bash
# Bare
claude mcp add pdf-tools -- uvx mcp-pdf
# With markdown_to_pdf support
claude mcp add pdf-tools -- uvx --from "mcp-pdf[markdown]" mcp-pdf
```
The `--` separator is required so the Claude CLI doesn't try to parse `--from` as one of its own flags.
### Manual config (Claude Desktop)
Edit `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `~/.config/Claude/claude_desktop_config.json` (Linux):
```json
{
"mcpServers": {
"pdf-tools": {
"command": "uv",
"args": ["run", "mcp-pdf-tools"],
"cwd": "/home/rpm/claude/mcp-pdf-tools"

}
}

### OCR not working
- Check Tesseract is installed: `tesseract --version`
- Install language packs: `sudo apt-get install tesseract-ocr-[lang]`
- Install language packs: `sudo apt-get install tesseract-ocr-[lang]` (Debian) or `sudo pacman -S tesseract-data-[lang]` (Arch)
### Table extraction failing
- Check Java is installed: `java -version`
- For Camelot issues, ensure Ghostscript is installed
- For Camelot issues, ensure Ghostscript is installed: `gs --version`
### `markdown_to_pdf` errors
- "pandoc binary not found" → install pandoc (see System Dependencies)
- "No PDF engine found" → install at least one of `xelatex`, `pdflatex`, `tectonic`, `weasyprint`, `wkhtmltopdf`
- "Pandoc died with exitcode 43" + `mktexfmt` errors → your TeX install is missing format files; rebuild with `sudo fmtutil-sys --all` or use a different engine via `pdf_engine="weasyprint"`
- The tool reports `detected_engines` in its response — check that field to see what's actually available
### Large PDF issues
- Process specific pages: `pages=[0, 1, 2]`
- Process specific pages: `pages="1-10"` or `pages="1,3,5"`
- Increase memory: `export JAVA_OPTS="-Xmx2g"`

- "Extract all tables from /path/to/report.pdf and format as markdown"
- "Convert /path/to/document.pdf to markdown format"
- "Extract images from the first 5 pages of /path/to/presentation.pdf"
- "Build a PDF from /path/to/notes.md with a table of contents"
## 7. Verify the Built-in Test
Convert this README itself to PDF as a smoke test once everything is wired up:
```python
markdown_to_pdf(
markdown_path="QUICKSTART.md",
output_path="/tmp/quickstart.pdf",
toc=True,
)
```
The response includes `detected_engines` so you can see exactly what's installed on your host.

### Picking a PDF engine for `markdown_to_pdf`
Pandoc takes markdown → HTML or LaTeX → PDF. The LaTeX path produces the most polished output but needs a TeX install. Trade-offs:
| Engine | Disk size | Notes |
|--------|----------|-------|
| **`tectonic`** | ~30 MB | **Recommended for new installs.** Single static binary. Downloads LaTeX packages on demand — no upfront mass-install. |
| `xelatex` + `texlive-latex-extra` | ~500 MB | Best output once installed. Use if you already run TeX. The `-extra` package matters: pandoc's default template needs `lastpage`, `xcolor`, `framed`, `fancyhdr`, etc. — all of which live there, **not** in `texlive-xetex`. |
| `xelatex` alone (just `texlive-xetex`) | ~200 MB | **Often breaks.** Expect `! LaTeX Error: File 'X.sty' not found` on real docs. |
| `weasyprint` | ~40 MB | Pure-Python (`pip install weasyprint`) + cairo/pango system libs. HTML/CSS path — no LaTeX. Good for simple docs; weaker on math, footnotes, citations. |
| `wkhtmltopdf` | ~40 MB | Older HTML-to-PDF tool. Adequate but less actively maintained. |

# Option A — tectonic (smallest, downloads packages on demand)

## Optional Extras

| `mcp-pdf[tables]` | `camelot-py`, `tabula-py` | Higher-accuracy table extraction (also needs Java + Ghostscript) |
| `mcp-pdf[markdown]` | `pypandoc` | `markdown_to_pdf` tool (also needs pandoc binary) |
