Announcing Cairnkeep: Durable, Local-First Memory for Coding Agents, Without the Autonomy
I have been building Cairnkeep since early July: project-scoped memory that survives sessions and crosses harnesses, a retrieval-first protocol agents must follow instead of new autonomy, least-authority MCP surfaces (read-only tool profiles, capability gates, immutable context packs), and optional, explicit opt-ins for everything networked. This post is the what and the why, the production deployment I run it in (a VPS-hosted memory server for a four-machine fleet, with the work laptop deliberately isolated), the 26-lesson learning path with its course labs repo, and the companion video series on my BitsEntangled YouTube channel.
