What it is
Give your AI agent typed decisions instead of free text. evaluate is an MCP server that lets Claude Code, Claude Desktop, Codex, and pi call TypeSafe's Jev model and get back probabilities they can branch on. One command, evaluate setup mcp, registers it with the first three (if detected); evaluate setup pi covers pi.
Getting started
From the README:
curl -fsSL https://raw.githubusercontent.com/itsmostafa/system-one-connector/main/install.sh | shWhere the decision sits
typesafe-mcp calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.
Models it references: Jev.
How active it is
Created 2026-09-17, last pushed 2026-10-25, 357 stars and 43 forks when we read it on 2026-11-02. Everything in this category is weeks old at most, so a stale push date means something different here than it would on a mature project. Check the repository before you depend on it.
Find out what your data actually supports
We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
