MCP tools · 2 exposed · ~245 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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
audit_palette ~180

Audit chart colors for accessibility: pairwise OKLab ΔE separation under normal vision, deuteranopia, protanopia, tritanopia (published Machado 2009 matrices) and grayscale, plus WCAG 2.2 SC 1.4.11 non-text contrast (≥3:1) against the background. Returns per-vision findings with human-word bands and a pass/fail verdict with reasons.

NameTypeReqDescription
backgroundstringyesBackground color the chart marks render on.
colorsarrayyesPalette colors in slot order — any CSS color syntax (#hex, hsl(), rgb(), named).
modestringFloors preset. perceptual (default) fails what an eye can't tell apart (ΔE<2); redundant-encodings for palettes paired with dash/decal/shape channels; strict demands clear separation.

No output schema declared.

No examples provided.

audit_tokens ~65

Run the same audit against a chartaudit.config.json on disk — the config names a CSS or design-tokens file plus which tokens are the categorical palette, background, and semantic roles.
