Overview

What is EasyOCR MCP Server?

A Model Context Protocol (MCP) server that provides OCR capabilities using the open-source EasyOCR library. It allows AI agents to extract text from images (base64, files, or URLs) with support for over 80 languages.

How to use EasyOCR MCP Server?

Install dependencies with uv sync (optionally install PyTorch with GPU support). Configure language selection via the EASYOCR_LANGUAGES environment variable in your MCP client’s config.json. Run the server with uv run easyocr-mcp.py or mcp run easyocr-mcp.py, then invoke tools: ocr_image_base64, ocr_image_file, or ocr_image_url.

FAQ from EasyOCR MCP Server

How do I select which languages to recognize?

Set the EASYOCR_LANGUAGES environment variable to a comma-separated list of language codes (e.g., en,ch_sim,ja). Default is English.

What output formats are available?

Set the detail parameter to 0 for text-only results (list of strings) or 1 for full details (list of tuples containing bounding box coordinates, text, and confidence score).

Does the server require a GPU?

GPU usage is determined at installation time based on your PyTorch installation. Install PyTorch with CUDA support to enable GPU acceleration; otherwise the server runs on CPU.

How do I process an image from a URL?

Use the ocr_image_url tool. The server will fetch the image from the URL and perform OCR automatically.

What are the threshold parameters for paragraph detection?

width_ths and height_ths control how close bounding boxes must be to be merged into a paragraph (default 0.7). The paragraph parameter enables paragraph detection (default false).
