Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
compareVision Show a color under all three deficiencies ~74
Return how a single hex color appears under protanopia, deuteranopia and tritanopia at once, for a side-by-side comparison.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | yes | Hex color, e.g. #1a9641 |
| severity | number | – | Deficiency strength 0..1 (default 1) |
No output schema declared.
No examples provided.
plate Generate an Ishihara-style color-vision test plate ~134
Generate a pseudoisochromatic (Ishihara-style) test plate: a digit hidden in a field of dots whose colors are distinct to normal vision but collapse under the chosen deficiency. Returns the plate image. Use when asked to create a colorblindness test plate or demonstrate what a plate looks like. Reproducible from a seed.
| Name | Type | Req | Description |
|---|---|---|---|
| number | string | yes | The digit(s) to hide, e.g. "7" or "29" |
| seed | integer | – | Same seed -> identical plate (default 1) |
| type | string | – | Which deficiency the figure should collapse under (default deutan) |
No output schema declared.
No examples provided.
simulateColor Simulate a color under colorblindness ~114
Return how a single hex color appears to someone with a given type of color-vision deficiency (protan, deutan, or tritan). Set severity 0..1 for a partial deficiency (anomalous trichromacy); 1 is the full dichromat case.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | yes | Hex color, e.g. #d7191c |
| severity | number | – | Deficiency strength 0..1 (default 1) |
| type | string | yes | Color-vision deficiency type |
No output schema declared.
No examples provided.
simulateImage Recolor an image as a colorblind person sees it ~189
Recolor an image, chart, screenshot or mockup the way someone with color-vision deficiency sees it, and return the recolored image. Use this to SHOW what a design looks like through colorblindness (to check whether it stays readable, pair it with cvdsafe's checkImage). Reads PNG and JPEG — pass `path` for a local file, or a base64 `dataUri`. `type` picks the deficiency (default deutan); `severity` 0..1 sets strength.
| Name | Type | Req | Description |
|---|---|---|---|
| dataUri | string | – | Base64 data URI of the image, if you don't have a file path |
| path | string | – | Path to a local PNG or JPEG file, e.g. ./chart.png |
| severity | number | – | Deficiency strength 0..1 (default 1) |
| type | string | – | Which deficiency to render (default deutan) |
No output schema declared.
No examples provided.
