Jev MCP Server

Overview

Jev MCP Server brings typed decision-making with calibrated probabilities to your AI assistant. It implements TypeSafe System One, letting any MCP-compatible AI call Jev's tools directly to structure decisions and assign confidence levels during conversations and agent runs.

The server runs locally via the jev-mcp-server Python package, installed with uvx jev-mcp-server. It communicates over stdio and requires no authentication — just install and use. Version v0.2.2 is the latest release.

Jev MCP Server is categorized as a Development tool on mcp.site and integrates with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to verify ownership and keep information up to date.
