Screen Vision MCP Server

Give Claude Code the ability to see your screen

Screen Vision lets Claude capture screenshots, watch your screen in real-time with audio transcription, analyze video files, and read text via OCR. It runs locally as an MCP server — Claude sees what you see, when you ask.

Privacy & Security

All capture is local and on-demand — no background recording, no persistent process, no external transmission.

• Screen Vision runs as a local MCP server (stdio transport). It only captures when Claude explicitly calls a tool in response to your request.

• Captured images and transcriptions are sent only to your existing Claude Code session — the same endpoint all Claude Code traffic uses. No third-party services, no cloud storage.

• The server does not run in the background between Claude Code sessions. It starts when Claude Code starts and stops when it stops.

• No data is written to disk unless you explicitly ask Claude to save a file.

Quick Start

pip install screen-vision[ocr]

Then add to your Claude Code MCP config (.mcp.json):

{
  "mcpServers": {
    "screen-vision": {
      "command": "screen-vision-mcp"
    }
  }
}

System deps for OCR and video:

brew install tesseract   # Required for OCR (read_screen_text)
brew install ffmpeg      # Required for video analysis (analyze_video)

"Take a screenshot of my screen"          → capture_screen
"Capture the Chrome window"               → capture_window
"Watch my screen for 1 minute"            → watch_screen (with audio transcription)
"Analyze the video at ~/Downloads/demo.mp4" → analyze_video
"Read the text on my screen"              → read_screen_text
"What window am I in?"                    → get_active_context (no screenshot)
"What's on my screen right now?"          → understand_screen (AI analysis)

Security

Screen Vision includes security controls for corporate environments:

• PII/PCI scanning — Detects credit card numbers, SSNs, phone numbers, email addresses in OCR text

• App deny-list — Blocks captures of Slack, Teams, Zoom, banking apps, password managers

• Call detection — Blocks captures during active audio calls

• Rate limits — 200 captures/session, 2s minimum interval, 5min max watch duration

• Audit logs — All captures logged to ~/.screen-vision/audit.log

Set SCREEN_VISION_MODE=work to enable all security controls. Default mode is personal (no restrictions).
