README
mcp-bench-router
MCP server that delegates design tasks to whichever model currently tops designarena.ai's crowdsourced leaderboard, via OpenRouter.
Why?
AI coding assistants produce mediocre frontend/design output. designarena.ai maintains a live leaderboard of the best design models, updated every 2 hours. This MCP server lets Claude (or any MCP client) automatically route design tasks to the current best model.

Usage Examples
Check who's #1:
"Use get_best_design_model to see the current top design model"
Browse rankings:
"Show me the top 20 design models for websites"
Generate a design:
"Use query_design_model to create a landing page for a SaaS product"
Use a specific model:
"Use query_specific_model with claude-sonnet-4-5 to design a dashboard"
How It Works
- Fetches live rankings from designarena.ai's API (cached 2hr)
- Maps arena model names to OpenRouter IDs (static + dynamic + fuzzy matching)
- Skips codename/unreleased models and picks the best available one
- Routes the prompt through OpenRouter's API
