Open Memex Overview

The open-memex MCP server gives MCP-capable coding editors shared local memory backed by Markdown files and a SQLite FTS5 index. It exposes tools for checking memory state, submitting drafts, proposing and promoting project memories, resolving conflicts, and mapping GitHub pull-request status to review states. Use it when multiple coding agents need the same project knowledge without sending memory to a cloud service.
