## Features

- Screenshot capture (left half, right half, full screen)
- OCR text recognition (supports Japanese and English)
- Multiple output formats (JSON, Markdown, vertical, horizontal)

## OCR Engines

This server uses two OCR engines:

1. [yomitoku](https://github.com/kazuph/yomitoku)
   - Primary OCR engine
   - High-accuracy Japanese text recognition
   - Runs as an API server

2. [Tesseract.js](https://github.com/naptha/tesseract.js)
   - Fallback OCR engine
   - Used when yomitoku is unavailable
   - Supports both Japanese and English recognition

A4.1/5.0

Scored across 1 tool

Disambiguation5/5

With only one tool, there is no possibility of ambiguity or overlap between tools. The single tool 'capture' has a clearly defined and distinct purpose.

Naming Consistency5/5

A single tool inherently has perfect naming consistency, as there are no other tools to compare against. The tool name 'capture' is clear and descriptive.

Tool Count2/5

One tool is too few for most server purposes, as it limits functionality and flexibility. While the tool is feature-rich with options, a single tool feels thin and may not cover all potential use cases for a screenshot utility.

Completeness3/5

The tool provides core screenshot and OCR functionality, but there are notable gaps such as no tools for managing saved screenshots (e.g., list, delete), adjusting OCR settings, or handling different output formats beyond the provided options. The surface is functional but incomplete.
