DeskKit — Agentic Commerce for Razorpay AI Buildathon

Track 1: AI Growth & Agentic Commerce

An autonomous procurement agent that makes a merchant (DeskKit) transactable by an AI buyer, end to end — with every money action explainable, bounded, and gated, and a live audit trail.

What it does

DeskKit is a small office-supplies merchant on Razorpay. This project builds an AI agent that:

• Browses DeskKit's catalog via an MCP tool interface (agent-readable catalog)

• Reasons about purchases and executes real Razorpay test-mode orders

• Enforces a strict monthly budget with two-tier gating: auto-approve under ₹3,000, manual approval required above it, hard block if it would exceed ₹5,000/month

• Persists spend across sessions — the budget genuinely behaves like a monthly limit, not a per-run reset

• Proactively suggests complementary items (upsell/cross-sell) after a successful purchase

• Includes a second AI agent that autonomously generates procurement requests — demonstrating real agent-to-agent commerce, not just human-to-agent

Every decision is traced in LangSmith for a full audit trail, and visualized live in a Monthly Ledger dashboard showing approved/pending/blocked counts and order history.

Why this matches the track

"Every money action explainable, bounded and gated. Show the audit trail and one failure handled gracefully."

This project handles four distinct failure/edge cases gracefully: budget block, approval gate, requests for items not in the catalog, and partial fulfillment of an over-scoped agent-to-agent request — each with clear reasoning and real alternatives, never a silent failure or forced override.

Tech stack

• FastAPI — backend + UI

• LangGraph (ReAct agent pattern) — reasoning and tool orchestration

• MCP (Model Context Protocol) — catalog and checkout exposed as agent-callable tools

• Groq (openai/gpt-oss-120b) — LLM inference

• Razorpay Python SDK — real test-mode payment orders

• LangSmith — observability and audit trail

• Persistent JSON-based spend tracking

Demo

Type an instruction (e.g. "Buy 10 USB-C cables and 1 laptop stand"), or click Simulate Requester Agent to see a second AI generate its own purchase request — true agent-to-agent commerce.
