Usage

MCP Server Usage

The MCP server provides two tools for document processing:

1. Process Single Document

Convert a document or image file to Markdown:

{
  "name": "process_document",
  "arguments": {
    "file_path": "/path/to/document.pdf"
  }
}

Or with base64 content (useful for MCP clients):

{
  "name": "process_document",
  "arguments": {
    "base64_content": "base64_encoded_file_content",
    "file_name": "document.pdf"
  }
}

2. Get Supported Formats

Get information about supported file formats:

{
  "name": "get_supported_formats",
  "arguments": {}
}

Python Tool Usage

For direct command-line usage:

# Process all files in the input directory
python docmistral.py

# Convert a single file
python docmistral.py --file document.pdf

Custom Directories

Specify custom input and output directories:

python docmistral.py --input /path/to/docs --output /path/to/markdown

Command Line Options

• --input, -i: Input directory (default: input)
• --output, -o: Output directory (default: output)
• --mistral-api-key, -k: Mistral AI API key (required)
• --file, -f: Convert a single file instead of a directory
