Common questions
Is Shopfront Chennai Local Commerce safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 20 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

1. The Core Novelty & Positioning
One line: Shopfront makes local businesses visible to AI assistants.
Tagline: *“Be the answer when people ask AI.”*
Short form: *“Local shops, found by AI.”*
┌────────────────────────────────────────────────────────────────────────┐
│ CUSTOMER ASKS AI: │ │ "Where can I get my iPhone battery replaced in Adyar right now under │ │ ₹2,000?" │ ├────────────────────────────────────────────────────────────────────────┤ │ WITHOUT SHOPFRONT: │ │ ❌ "I don't have real-time access to local shops or current prices. │ │ You may want to check Google Maps or call nearby stores." │ ├────────────────────────────────────────────────────────────────────────┤ │ WITH SHOPFRONT (MCP): │ │ ✅ "I found A1 Electronics in Adyar (450m away).

Shopfront bridges the gap between physical urban retail and conversational intelligence. By turning neighborhood shops into queryable, authenticated nodes on the Model Context Protocol (MCP), merchants gain direct customer inquiries without building custom mobile apps or forfeiting 30% aggregator commissions.
2. The Breakdown of Urban Apps vs. The AI Shift
Urban commerce is experiencing a structural paradigm shift driven by consumer app fatigue and conversational AI:
flowchart TD
subgraph TheAppTrap["The Separate Franchise App & Marketplace Trap"] A1["Separate App per Franchise (McDonald's app, Domino's app, Swiggy, Zomato, Urban Company)"] A2["Severe App Fatigue (Users delete single-use apps; refuse to install 30 separate apps)"] A3["20% to 30% Aggregator Commissions (High take-rates erode independent merchant margins)"] A4["Walled-Garden Data Silos (Customer phone numbers masked; zero direct relationship)"] A1 --> A2 --> A3 --> A4 end
subgraph TheAIShift["The Conversational AI Revolution"] B1["Users Ask AI Instead of Opening Apps ('Find me a MacBook technician near Adyar')"] B2["AI Assistants Get ZERO Data (LLMs cannot read fragmented closed apps)"] B3["Result: Hallucinated defunct numbers or dead ends"] B1 --> B2 --> B3 end
TheAppTrap -.->|Broken Paradigm| Solution["Shopfront: The Authoritative Live Layer"] TheAIShift -.->|Needs Ground Truth| Solution
The Three Critical Industry Breakdown Points:
- App Fatigue: Customers do not want to download, register, and update 30 different mobile apps for every local bakery, barber, and motorcycle garage.
- The Aggregator Tax: Conventional aggregators extract 20% to 30% of gross transaction volume and mask customer identities, preventing merchants from building long-term loyalty.
- The AI Search Blind Spot: When consumers ask Claude, Cursor, or ChatGPT for local recommendations, LLMs hallucinate or return generic blog scrapes because brick-and-mortar stores have no standard API or protocol representation.
3. The Solution: Three Key Differentiators
Shopfront replaces the fragmented app nightmare with a unified, protocol-driven architecture:
| Differentiator | Traditional Aggregators & Franchise Apps | Shopfront (MCP Engine) |
|---|---|---|
| 1. AI-Native Protocol | ❌ Walled gardens; closed to AI assistants; invisible to conversational search. | ✅ Native Model Context Protocol (MCP) server readable by Claude, Cursor, ChatGPT, and custom agent sidecars. |
| 2. One Listing vs. 20 Apps | ❌ Merchants spend ₹1,50,000+ building custom apps that users immediately uninstall. | ✅ One low-cost, commission-free listing that automatically syndicates across all AI assistants. |
| 3. Owner-Controlled Direct Contact | ❌ Masked phone numbers; platform lock-in; delayed weekly payouts. | ✅ Direct WhatsApp & telephone connection with pre-filled enquiry templates. Merchants keep 100% of revenue. |
4. Deep Customization: You Decide What AI Says
Shopfront provides local merchants with absolute sovereignty over their data. Through the mobile-first Owner Portal, owners decide exactly what AI assistants know and recommend:
mindmap
root((Owner Customization)) Hours & Shift Breaks Real-time IST schedule Afternoon lunch breaks Temple & festival closures Exact Rupee Pricing Fixed menu prices Transparent price ranges Warranty terms Live Availability 1-thumb out-of-stock switches Capacity limits Service Area & Coordinates Millimeter PostGIS location Locality bounding polygon Craftsmanship & Story 20+ years experience Specialist certifications WhatsApp Opening Template Pre-filled item context Direct wa.me deep links Bilingual Localization Tamil keywords ஷாப்ஃபிரண்ட் English terminology
The 8 Signature Customization Levers:
- 1. Operating Shifts & Lunch Breaks: Configure discrete shift intervals (e.g. 09:00–13:00 and 16:30–21:30) and upcoming holiday dates. AI never sends customers to a closed shutter.
- 2. Exact Rupee Pricing: List precise prices (e.g. *iPhone Battery: ₹1,800*) to qualify high-intent customers and eliminate haggling.
- 3. Instant Availability Toggle: Flip an item unavailable with a single thumb-tap from your phone when parts run out. AI updates immediately.
- 4. Spatial Service Area: Pinpoint exact physical coordinates and service radiuses in PostGIS (SRID 4326).
- 5. Authentic Brand Story: Provide background on your techniques, heritage, and quality guarantees for AI to champion.
- 6. Pre-Formatted WhatsApp Message: Customize the greeting message generated when customers click your action link.
- 7. Bilingual Tamil & English Support: Enable native Tamil script matching alongside standard English.
- 8. Persistent "AI Preview": A live dashboard card in the Owner Portal showing the exact conversational response and raw MCP JSON that AI assistants receive.
5. System Architecture & Request Lifecycle
Shopfront combines sub-25ms PostGIS SQL retrieval with an LLM semantic decision reranker and a fail-open circuit breaker.
