How to Use the Deterministic Color Engine MCP in Windsurf

Q: How does the Deterministic Color Engine help Windsurf Cascade build accessible themes?

Cascade uses manipulateluminance to calculate and apply exact contrast ratios. It adjusts background and text colors programmatically, bypassing manual Figma checks.

Q: Can I generate palettes using the Deterministic Color Engine inside Windsurf?

Yes. Cascade calls generatecolorpalette with a seed color to generate a set of complementary or analogous values, then writes them directly to your theme file.

Q: Does this MCP Server support all CSS formats?

Yes, it supports HEX, RGB, and HSL. The convertcolor tool handles the math to swap between them instantly.

Q: How do I configure this Deterministic Color Engine with Windsurf?

Open your mcpconfig.json file in Windsurf and add the server configuration under the mcpServers key. Cascade will auto-discover the tools immediately.

Give Windsurf Cascade the math engine it needs to build accessible, color-accurate UI systems on the fly.

Automate WCAG contrast checks in Windsurf

The `manipulate_luminance` tool gives Cascade the power to mathematically adjust UI contrast ratios on the fly using this MCP Server. When your autonomous agent detects an accessibility violation in your CSS, it calls this tool to shift the luminance value up or down by a precise percentage. Instead of waiting for a manual design review, Cascade handles the math locally. It writes the updated color straight into your variables file, solving contrast issues before you even commit.

Convert CSS colors directly inside Windsurf files

The `convert_color` tool translates any HEX, RGB, or HSL value into all three formats simultaneously. This lets Cascade inspect your current stylesheets and convert legacy formats to modern HSL without breaking your build. Cascade runs this tool to match your design system's preferred format. It replaces inconsistent color strings across your entire workspace in a single autonomous step.

Build UI themes using this MCP Server

The `generate_color_palette` tool calculates perfect analogous or complementary palettes from a single seed color. Cascade uses this mathematical output to construct entire UI themes directly in your codebase. You supply the primary brand color, and Cascade handles the rest. It generates the variations, builds the theme object, and wires it into your React code.

Setup guide

Set up Deterministic Color Engine MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the Deterministic Color Engine MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my Deterministic Color Engine payment history." If connected, Cascade will call the Deterministic Color Engine tools directly. You will see a green dot next to the server name in the MCP panel.
