The MCP Marketplace
& AI-Mediated Commerce
How AI agents, a universal connector store, and human oversight combine to reshape the way the world buys, sells, and delegates daily tasks.
👤 The User
Entry Point
📱
AI Life Assistant App
User speaks intent in natural language. "Handle my Monday tasks." No menus. No navigation. Just intent.
Control
✅
Confirmation Dashboard
Every action staged for single-tap approval. Daily summary of what the AI did, proposed, or flagged.
Trust Layer
🔐
Spending Limits & Prefs
User defines budgets, trusted merchants, and recurring pre-authorisations. AI acts only within those bounds.
Intent & Confirm
Actions & Summary
🤖 AI Agent Layer
Orchestration
🧠
AI Orchestrator
Parses intent → decomposes into tasks → sequences MCP connector calls → handles retries and errors.
Discovery
🔍
MCP Store Client
Queries the marketplace to find the right connector for each sub-task. Loads tool definitions on demand — not all at once.
Memory
💾
Persistent Memory
Stores user preferences, confirmed patterns, trust history, and past actions to improve over time.
Payments
💳
Payment Router
Routes confirmed transactions via licensed processors — Stripe, Google AP2, Visa Trusted Agent Framework. Never holds funds directly.
MCP Protocol
JSON-RPC 2.0
🏢 Business Layer

How Commerce Evolves
From human navigation to delegated AI agents — five phases, one direction.
2000–2020
Websites & Apps
Human navigates. Human clicks. Human pays. Every step is manual.
2020–2024
AI-Assisted Search
AI recommends. Human still decides, navigates, and transacts.
2025–2027
Human-in-the-Loop
AI stages complete actions. Human reviews and taps confirm. ← We are here
2027–2030
Delegated Autonomy
Pre-authorised domains. AI acts within limits. Human reviews summaries.
2030+
Full Autonomy
AI manages the household stack. Human sets goals. Agent handles everything.
The Autonomy Roadmap
AI earns the right to act independently — one trust milestone at a time.
1
Stage 1 · Launch Now
Human-in-the-Loop
AI researches, composes, and stages every action. User confirms each transaction individually. Full transparency, zero surprises.
⏱ 2025 – 2026
2
Stage 2 · Near Horizon
Pre-authorised Tasks
Recurring, predictable tasks — utility bills, fixed subscriptions — execute automatically within user-defined spending caps.
⏱ 12–18 months post-launch
3
Stage 3 · Mid Term
Category Autonomy
User delegates entire life domains — groceries, travel, healthcare bookings — with weekly limit and daily summary review.
⏱ 2027 – 2028
4
Stage 4 · The Vision
Full Autonomy
AI manages the complete household commerce stack. Human defines goals and budgets. The agent handles all execution — like having a trusted personal manager.
⏱ 2030+
