IWE Overview

IWE MCP server connects an AI agent to a folder of linked Markdown notes through the `iwec` MCP server. Agents can explore, search, read, create, edit, and organize project memory while people continue managing the same files directly. Run it with the notes directory as its working directory, making it suitable for project context, decisions, plans, and other durable knowledge. Reach for IWE when agent memory should remain visible, portable, and stored alongside the project rather than in a hosted service.

Primary Use Cases for IWE:
  • Store project decisions for later agent sessions
  • Search technical notes during development
  • Save plans and lessons as editable Markdown
  • Organize linked project context with an AI agent
