Implementation Reference

• pdfco/mcp/tools/apis/conversion.py:649-691 (handler)

  Primary MCP tool handler for 'image_to_pdf'. Uses @mcp.tool() decorator for registration and schema definition via Pydantic Fields. Constructs ConversionParams and delegates to convert_from helper to invoke PDF.co /pdf/convert/from/image API.
