Auto-Snap MCP

Auto-Snap MCP 📸

Automated screenshot capture and document processing for MCP Clients

Turn your screenshots into PDFs automatically! Auto-Snap lets your MCP client capture windows, process documents, and create PDFs with simple natural language commands.

🚀 Quick Start

Which Option Should I Choose?

🐳 Docker → Zero setup, works everywhere (recommended)
🪟 WSL2 → Windows users with WSL2 installed
🐧 Linux → Native Linux

Setup Steps

1. Get Auto-Snap:

git clone https://github.com/your-repo/auto-snap-mcp
cd auto-snap-mcp

2. Install dependencies (Linux only):

# Skip this step if using Docker
sudo apt install -y wmctrl xdotool tesseract-ocr
uv sync

3. Configure Claude Desktop:

Edit ~/.claude/claude_desktop_config.json and add one of these:

🐳 Docker (Recommended - No setup needed!)

{
  "mcpServers": {
    "auto-snap-mcp": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm",
        "-e", "DISPLAY=:0", 
        "-v", "/tmp/.X11-unix:/tmp/.X11-unix:rw",
        "-v", "${HOME}/auto-snap-captures:/app/captures:rw",
        "mcp/auto-snap-mcp:latest"
      ]
    }
  }
}

🪟 WSL2 (Windows with WSL2)

{
  "mcpServers": {
    "auto-snap-mcp": {
      "command": "wsl.exe",
      "args": [
        "bash", "-c",
        "cd /home/YOUR_WSL_USERNAME/auto-snap-mcp && DISPLAY=:0 /home/YOUR_WSL_USERNAME/.local/bin/uv run python server.py"
      ]
    }
  }
}

🐧 Linux Native

{
  "mcpServers": {
    "auto-snap-mcp": {
      "command": "uv",
      "args": ["run", "python", "server.py"],
      "cwd": "/home/YOUR_USERNAME/auto-snap-mcp",
      "env": {"DISPLAY": ":0"}
    }
  }
}

4. Restart Claude Desktop and verify it works:

"List all my open windows" ← Start with this to test the connection
"Capture this PDF and convert to images"
"Take 5 screenshots and make them into a PDF"

✅ Working? You should see your windows listed. If not, check the 🚨 Not Working? section below.

📁 Where Your Files Are Saved

By default, all your captures go to:

~/auto-snap-captures/

Full path examples:

Linux: /home/username/auto-snap-captures/
WSL2: /home/username/auto-snap-captures/
Windows (Docker): C:\Users\username\auto-snap-captures\

✨ What It Does & Commands to Try

📋 Document Capture

Screenshot any window or the entire screen
Capture multi-page documents automatically
Works with PDFs, presentations, web pages

🔍 Image Processing

Extract text from screenshots (OCR)
Enhance image quality automatically
Process multiple images at once

📄 PDF Creation

Convert screenshots to PDF instantly
Organize files with smart naming
Compress PDFs for smaller size

🎯 Commands to Try

"Capture this document as PDF" → Takes screenshots and creates a PDF

"Extract text from these images" → Runs OCR on screenshots

"Archive this presentation" → Screenshots all slides into one PDF

"List all my open windows" → See what you can capture

"Take 5 screenshots and make them into a PDF" → Multi-page capture

💡 Pro Tips:

Be specific: "Capture the Chrome window" works better than "take a screenshot"
Multi-step: "Screenshot this presentation and extract all the text"
Batch work: "Process all images in my Downloads and make PDFs"

Want to change where files are saved? See the 🎨 Customize Your Captures section below.

🛠️ System Support

✅ Linux (native X11)
✅ WSL2 (Windows apps from Linux)
⚠️ macOS (with XQuartz - experimental)

🚨 Not Working?

Common fixes:

# Check dependencies
uv run python -c "from capture import check_dependencies; print(check_dependencies())"

# Fix X11 display
export DISPLAY=:0

# Test the server
uv run python server.py

Still stuck?

Make sure the config path is correct: ~/.claude/claude_desktop_config.json
Restart Claude Desktop after config changes
Check Claude Desktop logs for errors

🎨 Customize Your Captures

Set where files go:

export AUTO_SNAP_OUTPUT_DIR="$HOME/Documents/Screenshots"

Organize by date:

export AUTO_SNAP_USE_DATE_SUBDIRS=true
export AUTO_SNAP_INCLUDE_TIMESTAMP=true

Custom file names:

export AUTO_SNAP_FILE_NAME_TEMPLATE="doc_{page:04d}"

🌍 Multiple Languages

Add more OCR languages:

sudo apt install tesseract-ocr-spa  # Spanish
sudo apt install tesseract-ocr-fra  # French
sudo apt install tesseract-ocr-deu  # German

Then tell Claude: "Process this document in Spanish"

🔐 Privacy

Everything runs locally on your machine
No cloud services or uploads
Only captures what you ask for
Automatic cleanup of temp files
