FreezeText MCP Server

OCR anything on your Mac screen from Claude, Cursor, or any MCP client.

This is the official Model Context Protocol server for FreezeText — a free native macOS app that freezes the screen and extracts text via Apple Vision OCR. Whether running videos, disappearing popups, protected PDFs, or hover tooltips — FreezeText makes any visible text copyable.

> You need the FreezeText app installed and running with its HTTP API enabled (Settings → API). This MCP server talks to the app's local API. Get FreezeText (free) at store.juergenkoller.software/apps/freezetext.

What you can do

> "Claude, OCR whatever is on my screen right now and summarize it."
>
> "Cursor, run OCR on this screenshot (base64) and extract the invoice number."
>
> "Search my FreezeText history for everything containing 'tracking number'."

The MCP server exposes 12 tools:

| Category | Tools |
|---|---|
| Capture & OCR | capture_screen (freeze + OCR), capture_region (OCR a specific rect), ocr_image (OCR a base64 image) |
| History | list_history, search_history, get_history_entry, add_history, delete_history_entry, clear_history, export_history (JSON/CSV) |
| OCR config | get_ocr_languages, set_ocr_languages |

All OCR runs locally via Apple Vision Framework — no cloud, no data transmission.
