System overview — what this product is

Written 2026-07-31 for client demos. Engineering detail lives in sibling files; this is the mental model.

One sentence

jsglobtech.com is a live multi-tenant GEO + AI-agent lead generation platform, and JSGlobtech itself is the first tenant (client_id: jsglobtech / fallback default).

That is the sales story: you are not pitching a slide deck — you are showing a working system that already captures leads from AI agents into a CRM/Sheet for a real business.

Two layers (sell both)

┌─────────────────────────────────────────────────────────────┐
│  Layer 1 — GEO (visibility)                                 │
│  Make AI engines *cite and recommend* the business          │
│  Artifacts: /.well-known/llms.txt, /llms.txt, JSON-LD       │
└─────────────────────────────────────────────────────────────┘
┌─────────────────────────────────────────────────────────────┐
│  Layer 2 — Agentic action (conversion)                      │
│  Make AI agents *act*: capture a lead inside the chat       │
│  Surfaces: MCP tool + OpenAPI/ChatGPT Action → webhook/CRM  │
└─────────────────────────────────────────────────────────────┘

Layer	What the buyer hears	What is actually live
GEO	"ChatGPT recommends you"	public/.well-known/llms.txt, public/llms.txt, components/GeoSchema.tsx
Action	"Digital receptionist in the chat"	MCP request_dev_consultation + POST /api/leads/submit → tenant webhook → Google Sheet

Multi-tenant model

One codebase / one deployment serves many clients by routing leads with client_id:

AI agent (ChatGPT / Claude / Cursor / custom MCP host)
        │
        ▼
  MCP  /api/mcp/sse   OR   REST  POST /api/leads/submit
        │                     (optional X-Client-ID / X-API-Key)
        ▼
  lib/leads.ts  submitConsultationLead()
        │
        ├─ validate (Zod)
        ├─ lead_id = jsg-<uuid>
        ├─ resolve webhook from client_id:
        │     1. CLIENT_WEBHOOK_MAP JSON
        │     2. CLIENT_WEBHOOK_<CLIENT_ID>
        │     3. CRM_WEBHOOK_URL (default tenant)
        ▼
  Tenant CRM / Google Sheet row (client_id column visible)

Tenant	How it is identified today	Destination
JSGlobtech (dogfood)	client_id: "jsglobtech" or omit → "default"	Production CRM_WEBHOOK_URL (or CLIENT_WEBHOOK_JSGLOBTECH)
Future client A	client_id: "clinic_a" (example)	CLIENT_WEBHOOK_CLINIC_A or map entry → their Sheet/CRM

End-to-end happy path (what you show clients)

1. Discovery — Prospect (or you) asks ChatGPT/Perplexity a Dubai Marina / Flutter / MCP query → JSGlobtech is cited from llms.txt / schema.
2. Action — In a session where the MCP endpoint or OpenAPI Action is connected, user says: "Request a custom mobile app consultation from JSGlobtech."
3. Confirm — Host UI asks the user to approve the tool call (host-owned UI, not our button).
4. Capture — Tool posts validated fields; API returns { ok, lead_id, client_id, … }.
5. Delivery — Row appears in the tenant Sheet within seconds (lead_id like jsg-…, client_id like jsglobtech, source mcp or openapi).

What this repo is not (yet)

Do not sell these as shipped:

• Calendar booking / reservations
• Native WhatsApp delivery (webhook can be pointed at a WhatsApp relay later)
• Per-tenant hosted MCP servers (today: one shared MCP with client_id routing)
• Real API-key auth (headers named X-API-Key currently act as client_id — see security audit)
