WHAT IT DOES

What convert_svg_string does on SVG Converter Tools MCP

WHY IT NEEDS A POLICY

Why convert_svg_string needs a policy

The tool converts SVG string input into image files (PNG, ICO, JPG), which constitutes data creation/generation. This is a Write operation—it produces new files but the conversion is reversible (output files can be deleted or regenerated). Confidence is moderate (0.75) because the tool's own description is empty, requiring inference from server context and sibling tool names.

From the tool's definition Tool name 'convert_svg_string' combined with server description indicating it 'Enables...conversion of SVG files to PNG, ICO, and JPG formats' indicates output file generation.
