How I built a "Sovereign Brain" for my AI agents (100% Local)

Hey IH, I've been obsessed with the 'Agentic Age' lately, but I quickly hit two walls:

1. Amnesia: Keeping Cursor, Claude, and Windsurf in sync is a nightmare.
2. Chaos: Giving an autonomous agent filesystem access is terrifying.

So I built Nucleus MCP. It's a local-first control plane that acts as a Hypervisor.

What I learned building this:

• LLMs don't need 'more tokens', they need better context governance.
• Local Sovereignty is the only way I'm comfortable letting an agent touch my code.
• 'Recursive Mounter' logic is the secret to scaling tool-use without bloating the context window.

I'm launching on Product Hunt this Tuesday, but I wanted to share the technical background with the IH community first. If you're building in the MCP ecosystem or struggling with agent memory, I'd love to trade notes.
