How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100

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 →
code Library code ~262
The conversion as code to paste: the color-space JS call with its result and – where one exists for the space on the non-sRGB side – the colour-science (Python) equivalent verified against color-space (sRGB ↔ that space), with any named caveat. The color goes in as a CSS string or as values in `from` (default: sRGB 200, 100, 50).
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | a CSS color instead of `from` + `values`: '#ff8000', 'rebeccapurple', 'oklch(0.7 0.1 50)', 'lab(54% 80 67)', 'color(display-p3 1 0.5 0)' |
| from | string | – | source space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |
| to | string | yes | target space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |

convert Convert color ~387
Convert a color between any two of the 221 color spaces, identity included, in each space's conventional ranges (rgb 0-255, oklch L 0-1 / C 0-0.4 / H 0-360, lab L 0-100 …). The color goes in as a CSS string (`color`) or as channel values (`from` + `values`); a batch as `colors` – tuples in `from`, CSS strings, or both. Out-of-range in, unclamped out: `inRange` flags each channel against the target's conventional range (rgb below 0 means outside sRGB); null = undefined at that coordinate.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | a CSS color instead of `from` + `values`: '#ff8000', 'rebeccapurple', 'oklch(0.7 0.1 50)', 'lab(54% 80 67)', 'color(display-p3 1 0.5 0)' |
| colors | array | – | a batch: one tuple (in `from`) or CSS string per color, e.g. [[255, 128, 0], '#00ff80', 'oklch(0.7 0.1 50)'] |
| from | string | – | source space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |
| to | string | yes | target space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |
| values | array | – | one color in the source space, e.g. [255, 128, 0] for rgb |

css CSS color strings ~272
A color as CSS Color 4 strings — rgb(), hsl(), hwb(), lab(), lch(), oklab(), oklch() and color(display-p3 | a98-rgb | prophoto-rgb | rec2020 | srgb-linear | xyz-d65 | xyz-d50) — plus #hex inside sRGB. Converted, never gamut-mapped: a string is null where CSS would clamp it into a different color (rgb/hsl/hwb outside sRGB, lightness out of range). `gamut` is the smallest display gamut that holds the color.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | a CSS color instead of `from` + `values`: '#ff8000', 'rebeccapurple', 'oklch(0.7 0.1 50)', 'lab(54% 80 67)', 'color(display-p3 1 0.5 0)' |
| from | string | – | source space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |
| notations | array | – | only these, by library space id (default: all) |
| values | array | – | one color in the source space |
| Name | Type | Req | Description |

| gamut | string|null | yes | – |
| hex | string|null | yes | – |
No examples provided.
cube .cube LUT ~174
Render a conversion as a .cube LUT file (Resolve, Premiere, Final Cut, OBS, ffmpeg). The header carries the measured deviation vs the direct conversion. Pure per-channel transfers auto-emit 1D. Size ≤ 33 here (larger via the library or https://color-space.io/).
| Name | Type | Req | Description |
|---|---|---|---|
| from | string | yes | source space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |

No output schema declared.
No examples provided.
gamut Gamut membership ~211
Which standard display gamuts hold a color — sRGB ⊂ Display P3 ⊂ Rec. 2020, each tested in its own RGB box straight from the source space, the same ladder as the color-space.io gamut pill. `smallest` is the tightest one; null = beyond Rec. 2020. Membership only: nothing is gamut-mapped.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | a CSS color instead of `from` + `values`: '#ff8000', 'rebeccapurple', 'oklch(0.7 0.1 50)', 'lab(54% 80 67)', 'color(display-p3 1 0.5 0)' |
| from | string | – | source space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |

icc ICC profile ~157
One space as an ICC v2 profile (.icc): matrix + tone curve where the space is an RGB working space (Photoshop, OS color management), a CLUT on a Lab PCS otherwise (lcms, ArgyllCMS, ImageMagick). Returned as a base64 embedded resource; `class`, `pcs` and `bytes` describe it.
| Name | Type | Req | Description |
|---|---|---|---|
| grid | integer | – | CLUT lattice points per channel, CLUT profiles only (default 33 for 3 channels; fewer = a smaller file) |
| name | string | yes | the space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |
| Name | Type | Req | Description |

shader Shader code ~235
The conversion as shader source – GLSL (WebGL2; WebGL1 too unless the path reads a table), WGSL (WebGPU), HLSL (DirectX, Unity, Unreal) or MSL (Metal) – with an entry function `<from>_<to>` (hyphens stripped), e.g. `vec3 rgb_oklch(vec3 c)`, plus every function on the path. Each language is differentially tested against the library and compiled on real GPUs: use it instead of writing color matrices. HLSL and MSL need the optional peer `naga-wasm` installed beside color-space.
| Name | Type | Req | Description |
|---|---|---|---|
| from | string | yes | source space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |

| entry | string | yes | – |
| language | string | yes | – |
No examples provided.
space Space dossier ~102
The dossier of one color space: display name (as color-space.io shows it), description, channels + conventional ranges, defining references, provenance (year, author), illuminant/observer, encoding class, family and purpose, and its direct conversion neighbours.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | the space id, e.g. 'rgb', 'oklch', 'lab', 'slog3', 'rec709' (the 'spaces' tool lists all 221) |

What is the color-space MCP server?
color-space is an MCP server listed in the public MCP registry as io.github.colorjs/color-space. Conversions across 221 color spaces, tested against cited sources: CSS strings, gamut, LUTs. This page covers its npm package (color-space).
Is the color-space MCP server safe to use?
color-space scores 88 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the color-space MCP server expose?
color-space exposes 9 tools: convert, gamut, css, space, spaces, and 4 more. Their descriptions and schemas cost roughly 1,896 tokens of context every time the server is loaded.
Is the color-space MCP server still maintained?
color-space is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the color-space MCP server under?
color-space declares the CC0-1.0 licence, which is not on the OSI-approved list. Read the terms before using it at work, and note this covers the source only, not the cost of any service it calls.
