## What is mdshrink?

mdshrink is an MCP server that automatically converts PDFs and screenshots to compact Markdown **before** they hit Claude Code's context window. It preserves semantic content while reducing token usage by 5-10x.

### Why?

When you attach a PDF or screenshot in Claude Code:
- A typical 20-page PDF consumes **25k-40k tokens**
- A single screenshot consumes **1.5k-3k tokens** per image

Most of those tokens are visual redundancy - fonts, layout, whitespace - that the model doesn't need. mdshrink extracts the semantic content and discards the bloat.

## Installation

```bash
pip install mdshrink-mcp
claude mcp add mdshrink -- mdshrink
```

Restart Claude Code. That's it.

## Usage

Once installed, Claude Code will automatically call mdshrink tools before reading PDF or image files:

- **`compress_pdf`** - Converts PDFs to compact Markdown
- **`compress_image`** - OCR extracts text from screenshots
- **`get_compressed`** - Cache lookup (fast check)

Each conversion reports:
- `original_tokens` - Estimated tokens for native file
- `compressed_tokens` - Actual tokens in Markdown  
- `ratio` - Compression ratio (e.g., "5.2x")

## What It Compresses Well

| Type | Compression | Notes |
|------|-------------|-------|
| Text-native PDFs | 5-10x | API specs, RFCs, papers, contracts |
| Screenshots of text | 3-5x | Code, error messages, docs, terminal |
| Scanned docs | Varies |…
