**Rust-powered PDF library for Python.** Generate, parse, split, merge, and manipulate PDFs with native performance. Ships with a built-in [MCP server](#mcp-server) so AI agents can work with PDFs out of the box.

No C dependencies. No Java. No subprocess calls.

## Installation

```bash
pip install oxidize-pdf            # Core library
pip install "oxidize-pdf[mcp]"     # + MCP server for AI agents
```

**Platforms:** Linux (x86_64, aarch64) | macOS (x86_64, Apple Silicon) | Windows (x86_64)
**Requires:** Python 3.10+

## Why oxidize-pdf?

| | oxidize-pdf | Pure-Python libs | C/Java wrappers |
|---|---|---|---|
| **Performance** | Native (compiled Rust) | Interpreted | Native but heavy |
| **Dependencies** | Zero | Varies | Poppler, Java, Ghostscript |
| **Memory safety** | Rust ownership model | GC-dependent | Manual / GC |
| **Type stubs** | Full (mypy/pyright) | Partial | Rare |
| **AI-ready (MCP)** | Built-in | No | No |

---

## MCP Server

Give your AI agent full PDF capabilities in one line:

```bash
oxidize-mcp
```

The built-in [Model Context Protocol](https://modelcontextprotocol.io/) server exposes **12 tools**, **6 resources**, and **5 prompts** — compatible with Claude, GPT, and any MCP client.

### Claude Desktop integration

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "oxidize-pdf": {
      "command": "oxidize-mcp",
      "env": {
        "OXIDIZE_WORKSPACE": "/path/to/your/pdfs"
      }
    }
  }
}
```

### Available tools

| Tool | What it does |
|------|-------------|
| `read_pdf` | Read metadata — page count, version, encryption status, title, author |
| `extract_text` | Extract text from all pages or a specific page |
| `convert_pdf` | Convert to markdown, chunks, or RAG-optimized format |
| `create_pdf` | Create a new PDF with optional metadata |
| `save_pdf` | Save a session to disk, with optional encryption |
| `add_content` | Add pages, text, and graphics to a session |
| `annotate_pdf` | Add text annotations and highlights |
| `manipulate_pdf` | Split, merge, rotate, extract pages, reverse, overlay |
| `manage_forms` | Create, fill, read, and validate form fields |
| `secure_pdf` | Encrypt, check permissions, verify signatures |
| `extract_entities` | Extract structured entities from pages |
| `analyze_pdf` | Validate structure, detect corruption, check PDF/A compliance |

The server also exposes **resources** (session data, capabilities, version info) and **prompts** (guided workflows for summarization, data extraction, form filling, and more).

### Configuration

```bash
OXIDIZE_WORKSPACE=/path/to/pdfs oxidize-mcp
```

Or start programmatically:

```python
from oxidize_pdf.mcp.server import run
run()
```

## Python API

### Create a PDF

```python
from oxidize_pdf import Document, Page, Font, Color

doc = Document()
doc.set_title("My Document")
doc.set_author("Jane Doe")

page = Page.a4()
page.set_font(Font.HELVETICA, 24.0)
page.set_text_color(Color.black())
page.text_at(72.0, 750.0, "Hello from oxidize-pdf!")

page.set_font(Font.TIMES_ROMAN, 12.0)
page.text_at(72.0, 700.0, "Generated with Python + Rust.")

doc.add_page(page)
doc.save("output.pdf")
```

### Parse an existing PDF

```python
from oxidize_pdf import PdfReader

reader = PdfReader.open("document.pdf")
print(f"Pages: {reader.page_count}, Version: {reader.version}")

for i, text in enumerate(reader.extract_text()):
    print(f"--- Page {i + 1} ---")
    print(text)
```

### Operations

```python
from oxidize_pdf import split_pdf, merge_pdfs, rotate_pdf, extract_pages

split_pdf("input.pdf", "output_dir/")                       # Split into individual pages
merge_pdfs(["part1.pdf", "part2.pdf"], "merged.pdf")         # Merge multiple PDFs
rotate_pdf("input.pdf", "rotated.pdf", 90)                   # Rotate all pages
extract_pages("input.pdf", "subset.pdf", [0, 2, 4])          # Extract specific pages
```

### Graphics

```python
from oxidize_pdf import Document, Page, Color

doc = Document()
page = Page.a4()

page.set_fill_color(Color.hex("#3498db"))
page.draw_rect(72.0, 700.0, 200.0, 100.0)
page.fill()

page.set_stroke_color(Color.red())
page.set_line_width(2.0)
page.draw_circle(300.0, 500.0, 50.0)
page.stroke()

doc.add_page(page)
doc.save("graphics.pdf")
```

### Types

```python
from oxidize_pdf import Color, Point, Rectangle, Margins, Font

# Colors
Color.rgb(1.0, 0.0, 0.0)          # RGB
Color.hex("#ff6600")               # Hex
Color.cmyk(0.0, 1.0, 1.0, 0.0)   # CMYK

# Geometry
Point(72.0, 720.0)
Rectangle.from_xywh(72.0, 72.0, 468.0, 648.0)
Margins.uniform(72.0)

# Fonts — all 14 standard PDF fonts
Font.HELVETICA    # Font.HELVETICA_BOLD
Font.TIMES_ROMAN  # Font.TIMES_BOLD
Font.COURIER      # Font.COURIER_BOLD
```

### Error handling

```python
from oxidize_pdf import PdfReader, PdfError, PdfIoError, PdfParseError

try:
    reader = PdfReader.open("missing.pdf")
except PdfIoError as e:
    print(f"I/O error: {e}")
except PdfParseError as e:
    print(f"Parse error: {e}")
except PdfError as e:
    print(f"PDF error: {e}")
```

Exception hierarchy: `PdfError` > `PdfIoError`, `PdfParseError`, `PdfEncryptionError`, `PdfPermissionError`

## Known limitations

- **Encryption write support**: `Document.encrypt()` configures encryption parameters but the underlying Rust library does not yet serialize the encryption dictionary to the PDF output. Reading encrypted PDFs works correctly.
- **CPython only**: PyPy and GraalPy are not supported.
