Perplexity

Convert CSS colors from the Claude Code CLI

The `convert_color` tool translates color strings between HEX, RGB, and HSL formats directly in your terminal. This allows your agent to parse design tokens in JSON files and convert them to the format required by your build scripts. You can command your CLI agent to batch-process a directory of design assets, converting every color format without opening a browser or design tool.

Run headless WCAG contrast fixes with this MCP Server

The `manipulate_luminance` tool programmatically shifts color luminance up or down. Your terminal agent can run this tool inside CI/CD pipelines to adjust dynamic theme files before they get packaged. If a build-time test flags a contrast issue, the agent runs the tool to bump the luminance, updates the source file, and pushes the fix.

Generate palettes via terminal scripts

The `generate_color_palette` tool calculates complementary and analogous color sets using a primary seed color. Your CLI agent can use this tool to generate runtime themes on the fly during static site generation. This eliminates the need for heavy external color libraries in your production bundle. The math happens at build time via the terminal.

Setup guide

Set up Deterministic Color Engine MCP in Claude Code

Prerequisites

Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
Active Vinkius subscription with a valid endpoint token

1

Run the add command

Open your terminal and run the command shown on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com. Use --scope user to make it available across all projects.
2

Verify the connection

Start a Claude Code session and type /mcp to list connected servers. You should see deterministic-color-engine-mcp with a green status indicator.
3

Start using tools

Ask Claude Code something like "Check my latest Deterministic Color Engine transactions." It will automatically discover and invoke the available Deterministic Color Engine tools.

Common questions about Deterministic Color Engine MCP in Claude Code

Run the `claude mcp add` command in your terminal, specifying the transport type and the server URL. Claude Code will configure it in your local settings.

Yes. Since Claude Code runs headlessly, you can execute scripts that call `manipulate_luminance` or `generate_color_palette` during your build steps.

No. The math is computed locally inside the secure Vinkius environment, providing instant conversions without external API calls.

Yes. Claude Code can read your theme files, pass each variable through `convert_color`, and write the output back to your stylesheet.

The server only processes raw color strings like HEX codes or HSL values. Your files are read and modified locally by your CLI agent, ensuring no source code leaves your machine.
