Openharness

OpenHarness is a local Model Context Protocol (MCP) server that enables seamless sharing of recent session metadata between coding AI agents like Claude Code, Codex CLI, and Gemini CLI. It acts as a lightweight discovery layer that connects agent sessions without altering your existing tool environment, providing session paths and metadata but never storing, relaying, or transforming session content. This is especially useful for developers or teams using multiple local coding agents who want cross-agent session awareness with minimal setup.
