Tools & Capabilities Breakdown

MCP Mermaid Tools (1)

generate_mermaid_diagram

Generate mermaid diagram and chart with mermaid syntax dynamically. Mermaid is a JavaScript based diagramming and charting tool that uses Markdown-inspired text definitions and a renderer to create and modify complex diagrams. The main purpose of Mermaid is to help documentation catch up with development.

Microcharts Tools (3)

find_microchart

Rank microcharts chart types against a plain-language question about data ("is it trending?", "error budget", "part to whole"). Returns candidates with the reason each matched. Start here when you know the question, not the chart.

get_microchart

Full wiring detail for one chart by slug: import paths, its props plus the shared props, data shape, best/avoid guidance, a copy-runnable example, and `sample` — the example as JSON props you can pass straight to render_microchart.

render_microchart

Render a chart to a finished, self-contained SVG (styles embedded) plus its generated alt text — for surfaces that can't run React. Pass the series as `data`; put other props (value, target, curve, color, width) in `props`. Each chart takes its own data shape — get_microchart returns a valid `sample` to adapt.
