Nucleus is an internal project I've been dogfooding for months (originally published Dec 27, 2025: https://pypi.org/project/mcp-server-nucleus/0.1.0/). It's a local-first brain for AI agents (Cursor, Claude Desktop, Windsurf) with a Hypervisor for resource locking and full audit trails.
Key technical features-\nHypervisor: Resource locking with who/when/why metadata.\nAudit Trail: Every agent action logged to a local events.jsonl.\nLocal-First: Data never touches the cloud.\nUniversal Sync: One brain for all your IDEs.
It's early alpha, but the security logic is battle-tested in my own production apps. I'm open-sourcing it now to give folks a secure alternative for managing sensitive keys and memory.
Curious what you all think about the Hypervisor approach to resource locking."},"title":{"matchLevel":"none","matchedWords":[],"value":"Show HN: Nucleus MCP \u2013 Secure local-first memory for AI agents"},"url":{"matchLevel":"none","matchedWords":[],"value":"https://github.com/eidetic-works/nucleus-mcp"}},"_tags":["story","author_NucleusOS","story_46966203","show_hn"],"author":"NucleusOS","created_at":"2026-02-10T20:17:33Z","created_at_i":1770754653,"num_comments":0,"objectID":"46966203","points":2,"story_id":46966203,"story_text":"I built Nucleus because the current MCP ecosystem has a massive security gap.
