System One Connector
An MCP connector that gives an AI agent direct access to small judgment models such as Jev, CLM and Laya, returning a probability for each possible answer to a question instead of prose to parse.
System One Connector gives an AI agent direct access to judgment models such as Jev, CLM and Laya, built to answer a specific question with a probability for each possible answer rather than generating text the agent then has to interpret.
Its evaluate command connects Claude Code, Claude Desktop, Codex, Hermes and pi to TypeSafe's hosted Jev model, or to open System One models such as CLM and Laya that a user runs themselves, by pointing the connector at their own server. An agent names a question and its possible answers, such as whether something is urgent and which team owns it, and gets back a probability for each one that it can compare against a threshold.
It is a Go command-line tool that installs with a shell script and registers itself as an MCP server with each detected agent client.
