Agentcairn Overview

The ccf/agentcairn MCP server gives coding agents shared, local-first memory backed by a plain-Markdown vault and a rebuildable DuckDB retrieval index. It captures and redacts durable context, then combines BM25, semantic vector, and graph signals to recall relevant notes with project and validity metadata. Use it when multiple coding agents need one inspectable memory, especially across Claude Code, Codex, Cursor, or another MCP host. Install with uvx or through the supported Claude Code and Codex plugins.

Primary Use Cases for Agentcairn:
  • Share durable project context across Claude Code, Codex, and Cursor
  • Recall prior deployment decisions during a new coding session
  • Inspect and edit agent memory as Markdown in an Obsidian vault
  • Capture session context while redacting recognized credentials
