**Zero-token-output decision router MCP server powered by TypeSafe Jev.**

AI coding agents waste hundreds of reasoning tokens just deciding which file to edit, which route to pick, or whether a diff breaks tests. **jev-flash-router** evaluates context, code diffs, logs, or planning options and returns calibrated probabilities in ~150ms — with **$0.00 output token cost**.

✨ Features

⚡ ~150ms decisions — Lightning-fast evaluation via OpenRouter Decisions API
💸 Zero output token cost — output_tokens: 0 on every call
🧠 TypeSafe Jev — Powered by the cutting-edge ~typesafe/jev-latest model
🔌 MCP-native — Works seamlessly with Cursor, Windsurf, Claude Desktop & Claude Code
📦 Zero-config — Install via npx and go
🎯 Three decision formats: noul (binary), choice (categorical), score (rubric)

🚀 Quick Start

1. Install as an MCP server

No local clone needed — anyone can run it instantly:

npx -y jev-flash-router

Or install globally via npm:
