Fast PaddleOCR MCP server - Extract text from images using PaddleOCR with optimized performance

PaddleOCR-MCP

PaddleOCR MCP (Model Context Protocol) server and CLI tool that extracts text from images and outputs results in markdown format. Optimized for fast inference with GPU auto-detection.

MCP Server Configuration

The MCP (Model Context Protocol) server allows integration with MCP clients like Cursor, Claude Desktop, etc.

Use uvx directly (no installation required, automatically downloads from PyPI):

{
  "mcpServers": {
    "fast-paddleocr-mcp": {
      "command": "uvx",
      "args": ["fast-paddleocr-mcp"]
    }
  }
}

MCP Tool: ocr_image

The server provides a single tool called ocr_image that:

• Input: image_path (string) - Path to the input image file
• Output: Returns the path to the generated markdown file containing OCR results

Example: When called with image_path: "photo.png", it returns "photo.png.md" containing the recognized text.

See MCP_README.md for detailed MCP server documentation.

Usage

Basic Usage

The tool is optimized for speed by default with the following settings:

• Fast mode enabled (disables preprocessing for maximum speed)
• PP-OCRv4 (faster mobile models)
• 640px image size limit (faster processing)
• Auto GPU detection (uses GPU if available, falls back to CPU)

# Output will be saved as <image_name>.png.md
# Uses: fast mode + PP-OCRv4 + 640px + auto GPU detection
uvx --from . paddleocr-md image.png

# Specify custom output path
uvx --from . paddleocr-md image.png -o result.md

# Force CPU mode
uvx --from . paddleocr-md image.png --cpu

# Disable fast mode for better accuracy on rotated text
uvx --from . paddleocr-md image.png --no-fast

# Use PP-OCRv5 for better accuracy (slower)
uvx --from . paddleocr-md image.png --ocr-version PP-OCRv5

Default Optimization Settings

The tool is optimized for speed by default with these settings:

• ✅ Fast mode enabled: Disables textline orientation classification (skips one model)
• ✅ PP-OCRv4: Uses faster mobile models (PP-OCRv4_mobile_det, PP-OCRv4_mobile_rec)
• ✅ 640px image size limit: Faster processing (vs default 960px)
• ✅ Auto GPU detection: Automatically uses GPU if available, falls back to CPU
• ✅ Document preprocessing disabled: Skips unnecessary preprocessing steps

Customization Options

1. --no-fast: Disable fast mode for better accuracy

   • Enables textline orientation classification
   • Better accuracy on rotated text, but slower

2. --cpu: Force CPU mode

   • Overrides auto GPU detection
   • Explicitly use CPU

3. --gpu: Force GPU mode

   • Will fail if GPU not available
   • Use when you want to ensure GPU usage

4. --ocr-version PP-OCRv5: Use better accuracy version

   • PP-OCRv5 has better accuracy but slower than PP-OCRv4 (default)
   • Uses server models

5. --max-size <pixels>: Adjust image processing size

   • Default: 640px
   • Larger values (e.g., 960, 1280) = better accuracy, slower
   • Smaller values (e.g., 480) = faster, may reduce accuracy

6. --hpi: High-Performance Inference

   • Automatically selects best inference backend (Paddle Inference, OpenVINO, ONNX Runtime, TensorRT)
   • Requires HPI dependencies: paddleocr install_hpi_deps cpu/gpu
   • Best performance but requires additional setup

Examples

# Basic usage (uses all optimizations by default: fast + PP-OCRv4 + 640px + auto GPU)
uvx --from . paddleocr-md photo.jpg

# Process with custom output
uvx --from . paddleocr-md document.png -o extracted_text.md

# Better accuracy (slower) - disable fast mode and use PP-OCRv5
uvx --from . paddleocr-md image.png --no-fast --ocr-version PP-OCRv5 --max-size 960

# Force CPU mode
uvx --from . paddleocr-md image.png --cpu

# Use High-Performance Inference (requires HPI dependencies)
uvx --from . paddleocr-md image.png --hpi

Output Format

The tool generates a markdown file containing:

• Source image path
• List of detected text (one per line)

Example output (test_image.png.md):

# OCR Result

**Source Image:** `test_image.png`
