Color Engine Mcp
by aimsisecommunityv1.0.1
An MCP server that provides CSS color utilities for parsing, converting, gamut mapping, WCAG/APCA contrast checking, tint/shade ramp generation, and solving for a foreground color that meets a contrast target. It operates entirely in memory with no network or filesystem access.
From the registry: Six pure, in-memory CSS color tools: parse, convert, WCAG/APCA contrast, gamut map, ramps, solver
Install & configure
Prerequisites
- requiredInstall Node.js 20 or newerNode.js version 20 or higher is required to run the MCP server via npx.
Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `color-engine-mcp` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install Node.js 20 or newer** — Node.js version 20 or higher is required to run the MCP server via npx.
Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","color-engine-mcp"]
Note: The README recommends the npm package launch path via npx as the simplest install method. No repository clone, build step, or environment variables are required.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: The README recommends the npm package launch path via npx as the simplest install method. No repository clone, build step, or environment variables are required.
