## Example call (MCP tools/call, JSON-RPC 2.0)

```json

## Why generate_gauge_chart is rated High

This tool executes a server-side rendering pipeline involving ECharts SSR and rsvg-convert, which are external processes. While the primary purpose is chart generation (a form of output creation), it involves executing code and external binaries rather than simply reading or writing data. The blast radius is medium as misuse could trigger unintended process execution, though it is constrained to chart rendering.

From the tool's own definition: "'Generate a gauge chart' using 'Apache ECharts SVG SSR and rsvg-convert' — triggers external rendering processes (SSR + rsvg-convert binary execution) to produce chart output"

## Use case

AI agents invoke generate_gauge_chart to trigger actions in Kylin Offline MCP ECharts. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
