Jev MCP

A small, dependency-light MCP server that gives any MCP client typed, probabilistic decisions from Jev, TypeSafe's System One model, through OpenRouter or TypeSafe directly. Its 5 documented tools cluster into decide, classify, verify, rerank.

People who work with decision making, jev and openrouter and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Go.
