Jev MCP

Jev MCP is a Model Context Protocol server that provides typed, probabilistic decision-making capabilities using the Jev / System One model. It allows agents to perform classification, verification, reranking, and decision tasks by sending data and typed questions to the model, receiving calibrated answers with confidence scores and probability distributions. The server supports provider-agnostic access via OpenRouter or TypeSafe, ensuring safe credential handling and validated outputs.
