agentcairn is a local-first memory MCP server: your agent's memories live as Markdown in an Obsidian vault you own — the source of truth — with a rebuildable DuckDB index providing fast hybrid BM25 + vector + graph recall. It exposes tools to capture, recall, and manage those memories (non-lossy, with secret redaction) and works the same across Claude Code, Codex, Cursor, and any MCP host.
