StyleSeed Tokenizer
Generate and export design-system tokens (color, spacing, typography) from a brief so your app and docs stay visually consistent while you ship with AI agents.
Overview
StyleSeed Tokenizer is a MCP server for the Build phase that generates and exports automated design-system tokens for agent-driven UI work.
What is this MCP server?
- Remote MCP server over SSE hosted on Vercel (styleseed-tokenizer-mcp.vercel.app)
- Automated design-system token generation and export utility
- Optional EIP-3009 payment-signature header for premium settlement on remote calls
- Version 1.0.0 in Model Context Protocol server schema (2025-12-11)
- Agent-callable workflow: describe brand constraints → receive structured token artifacts
- Remote MCP version 1.0.0
- Single documented SSE remote endpoint on Vercel
- Optional payment-signature header for EIP-3009 premium settlement
What problem does it solve?
Solo builders waste hours syncing colors, spacing, and type across code, prompts, and docs because there is no single machine-readable token source the agent can update.
Who is it for?
Indie devs who want a repeatable token pipeline while iterating UI with Claude Code or Cursor and already run an MCP-capable client.
Skip if: Teams that only need a one-off palette in Figma with no code export, or anyone who cannot use remote MCP over SSE.
What do I get? / Deliverables
After you connect the remote SSE endpoint, your agent can produce export-ready design tokens you plug into CSS variables, Tailwind config, or component themes.
- Structured design-system token sets ready for export into code or docs
- Repeatable agent workflow for regenerating tokens as brand constraints change
Recommended MCP Servers
Journey fit
Design tokens are created while you are actively building the product UI, not during initial idea research or post-launch growth loops. Token output feeds component libraries, Tailwind/CSS variables, and Figma-adjacent workflows that sit squarely in frontend implementation.
How it compares
MCP design-token generator, not a full visual design or whiteboard skill.
Common Questions / FAQ
Who is StyleSeed Tokenizer for?
Solo and indie builders who ship UI with AI agents and want consistent design-system tokens generated and exported without manual spreadsheet work.
When should I use StyleSeed Tokenizer?
Use it during Build while defining or refactoring your frontend theme—before you lock components and while agents are still generating layout and style code.
How do I add StyleSeed Tokenizer to my agent?
Register the remote MCP server URL https://styleseed-tokenizer-mcp.vercel.app/api/mcp as an SSE transport in your agent's MCP config; add the payment-signature header only if your plan requires premium settlement.
