Openharness

If you're running multiple AI coding agents on the same machine and want them to reference each other's work, this server exposes two MCP tools that return local session file paths. Get agent sessions scans ~/.claude, ~/.codex, and ~/.gemini directories for recent JSONL or JSON session logs tied to a project path. Get agent session does the same for a single agent. The agent then reads those files directly using its own file access. No relay, no transformation, just discovery. Useful when you want Codex to review what Claude Code just worked on, or vice versa, without manually hunting down session logs or switching contexts.
