What generate_treemap_chart does on Kylin Offline MCP ECharts

RISK

Why generate_treemap_chart is rated Medium

This tool generates chart visualizations (SVG output) based on input parameters. Chart generation is a write operation—it creates new data artifacts. However, the severity is low because: (1) the operation is fully reversible (generated charts can be deleted or regenerated), (2) no data mutation or deletion occurs, (3) the blast radius of misuse is limited to consuming resources and creating unwanted chart files,…

From the tool's definition Tool name contains 'generate' and description states 'Generate a treemap chart'; the server creates SVG output files using ECharts SSR and rsvg-convert. These are reversible write operations that produce new chart artifacts.
