What it does

Plugs Highcharts' full visualisation library into any MCP Apps-capable AI client. Ask your AI to visualise data and it renders a live, interactive chart directly inside the chat panel — no copy-paste, no switching tabs. Supports 60+ chart types including financial candlestick charts, choropleth maps, Gantt timelines, multi-component dashboards, and standalone data grids.

Key features

6 rendering tools — render_chart, render_stock_chart, render_dashboard, render_map, render_gantt, render_grid
60+ chart types — full Highcharts Options API accepted, so any valid Highcharts config works
Auto light/dark theming — adapts to host theme; 15 built-in themes overridable via env var
Schema depth control — tune how much type info is sent to the LLM (0–3) to balance context vs accuracy
Live-updating charts — use data.csvURL + data.enablePolling for real-time data feeds
Prompt library — 6 built-in prompts for common patterns (dashboard scaffold, stock analysis, Gantt from task list)
