MCP tools — 3 exposed · ~333 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens

find_microchart Find a chart by question ~102

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.

Input Output Examples

Name	Type	Req	Description
dataShape	string	—	Optional filter, e.g. "number[]".
limit	integer	—	Max results (default 6).
question	string	yes	What the data needs to show, in plain language.

Name	Type	Req	Description
results	array	yes	—

No examples provided.

get_microchart Get a chart's props + example ~77

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.

Input Output Examples

Name	Type	Req	Description
slug	string	yes	Chart slug, e.g. "sparkline".

Name	Type	Req	Description
avoidFor	array	yes	—
bestFor	array	yes	—
dataShape	string	yes	—
encoding	object	yes	—
example	object	yes	—
interactiveImport	string	—	—
name	string	yes	—
props	array	yes	—
sample	object	—	Ready-to-render props — pass straight to render_microchart.
sharedProps	array	yes	—
slug	string	yes	—
staticImport	string	yes	—
status	string	yes	—
tagline	string	yes	—

No examples provided.

render_microchart Render a chart to SVG ~154

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.

Input Output Examples

Name	Type	Req	Description
data	—	—	Primary series (array), or a keyed object for charts that take one; omit for scalar charts.
format	string	—	`svg` (default) or `bare`.
props	object	—	Other props (value, target, color, …).
type	string	yes	Chart slug, e.g. "sparkline".

Name	Type	Req	Description
height	number	yes	—
library	string	yes	—
mimeType	string	yes	—
summary	string	yes	The chart's generated accessible name — its alt text.
svg	string	yes	—
width	number	yes	—

No examples provided.
