MODEL CONTEXT PROTOCOL · OPEN AGENT INFRASTRUCTURE

The Supervision Home Protocol

The sovereign interface connecting personal AI agents (Claude, Cursor, ChatGPT, and Arthur) to your verified home ledger, municipal permits, and contractor marketplace dispatch.

Sovereign Data Pledge: Client-scoped execution. Zero data selling or training of public models.

Launch Web App

1. Sovereign Property Vault

Your home receipts, paint codes, warranties, and smart lock credentials remain isolated in your personal vault. Agents connect via sandboxed MCP tools with granular permissions.

2. Marketplace Dispatch

Agents can programmatically call create_project_sow to translate messy diagnostic photos into trilingual contractor RFPs with milestone escrow.

3. Insurance & Tax Audit Trail

Every repair, permit, and capital improvement completed forms an unforgeable Property Passport—powering carrier underwriting discounts and IRS Section 121 capital basis shields.

Connect in Under 60 Seconds

Data Privacy & Sovereignty Guardrails

Zero Public AI Training · Client-Enforced Isolation

1. Encryption at Rest & in Flight: All property documents, receipts, and photos are encrypted via AES-256 and transmitted exclusively over TLS 1.3 endpoints.

2. Sovereign Isolation: Supervision does not sell, broker, or syndicate homeowner phone numbers or property records to advertising brokers or unsolicited contractor lead mills.

3. Granular Tool Scopes: Personal AI agents are restricted to explicit tool definitions. Third-party agents cannot modify financial bank accounts or authorize contractor payouts without physical homeowner confirmation.
