The sovereign, local-first Agent Operating System ā persistent memory, governance, compliance, and audit trails for any AI agent.

[!CAUTION] After the OpenClaw security crisis (1.5M API keys leaked, sleeper agents in skills), agent security is no longer optional. Nucleus is built security-first: hypervisor controls, resource locking, compliance governance, and full audit trails ā all 100% local.
šÆ The Problem
AI agents are powerful, but ungoverned:
- No memory ā every session starts from zero
- No audit trail ā no one knows why the agent did what it did
- No compliance ā regulators can't approve what they can't trace
- No sovereignty ā your data flows through someone else's cloud
For regulated industries (BFSI, healthcare, legal), this is a dealbreaker.
⨠The Solution: Sovereign Agent OS
Nucleus gives every AI agent a persistent brain with built-in governance:

š Quick Start (2 Minutes)
Install
pip install nucleus-mcp
nucleus-init
Try It
# See your sovereignty posture
nucleus sovereign
# Run a KYC compliance demo (15-minute BFSI demo)
nucleus kyc demo
# Apply EU DORA compliance
nucleus comply --jurisdiction eu-dora
# Generate audit-ready report
nucleus audit-report --format html -o report.html
# Browse decision trails
nucleus trace list
Configure (Claude Desktop / Cursor / Windsurf)
Add to your MCP config:
{
"mcpServers": {
"nucleus": {
"command": "python3",
"args": ["-m", "nucleus_mcp"],
"env": {
"NUCLEAR_BRAIN_PATH": "/path/to/your/.brain"
}

šļø Why Nucleus for Regulated Industries
Jurisdiction-Aware Compliance
One command to configure for any regulatory framework:
nucleus comply --jurisdiction eu-dora # EU DORA (7yr retention, kill switch)
nucleus comply --jurisdiction sg-mas-trm # Singapore MAS TRM (5yr, strictest HITL)
nucleus comply --jurisdiction us-soc2 # US SOC2 (1yr retention)
nucleus comply --report # Check compliance status
| Jurisdiction | Region | Retention | HITL Ops | Kill Switch |
|---|---|---|---|---|
eu-dora | EU | 7 years | 5 types | ā Required |
sg-mas-trm | Singapore | 5 years | 5 types | ā Required |
us-soc2 | US/Global | 1 year | 3 types | āŖ Optional |
global-default | Global | 90 days | 2 types | āŖ Optional |
KYC Compliance Demo
Built-in demo workflow showing how Nucleus governs a KYC document review:
nucleus kyc review APP-001 # Low risk ā ā
APPROVE
nucleus kyc review APP-002 # Medium risk ā ā ļø ESCALATE (PEP match)
nucleus kyc review APP-003 # High risk ā ā REJECT (sanctions)
nucleus kyc demo # Run all 3 in sequence
Each review generates:
- 5 automated checks (sanctions, PEP, document validity, risk factors, source of funds)
- Full decision trail stored as DSoR (Decision System of Record) trace
- HITL approval request for risky applications
- Sovereignty guarantee: all processing is local
Audit Reports
Generate audit-ready reports for regulators:
nucleus audit-report # Terminal text
nucleus audit-report --format json # JSON for APIs
nucleus audit-report --format html -o report.html # HTML for compliance officers
Sovereignty Status
See your full sovereignty posture:
nucleus sovereign
Shows: sovereignty score (0-100), memory health, governance posture, DSoR integrity, data residency guarantee.
