Cairn Overview

Cairn MCP server gives an MCP-compatible agent local tools for listing, reading, searching, editing, moving, tagging, importing, and retrieving files. It runs against a configured workspace directory, stores tags in portable `.uni` documents, and keeps filesystem data and optional indexes local. Read-only operations can run freely, while edits, moves, and deletes are annotated as destructive for client approval. Reach for it when an agent needs to organize notes or documents without an account, cloud service, or separate database.

Primary Use Cases for Cairn:
  • Organize a notes folder with agent-assisted file operations
  • Tag documents in a local workspace
  • Search and retrieve related notes
  • Import office documents into editable local files
