Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@CommerceOps MCP Server Diagnose the stalled order ORD-1002"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An AI-native, production-grade Model Context Protocol (MCP) server written in TypeScript, designed to enable AI Operations Agents to autonomously investigate and resolve complex e-commerce operational exceptions (stuck orders, missed payment webhooks, warehouse fulfillment delays, and oversold inventory).
Raw Operational Signals (No Pre-Baked Diagnostic Labels):
Seed orders store only realistic backend fields (order_status, payment, inventory, fulfillment). diagnose() computes root-cause explanations and evidence dynamically at runtime.
Strict Bounded Action Enum & Safety Policy:
All state mutations are restricted to a closed enum of actions (refund_duplicate_charge, requeue_to_warehouse, release_reserved_stock, resync_shipping_address). Every resolution call structurally enforces a pre-execution safety check (evaluate_safety).
Universal Risk-Score Pre-Gate & Central Policy Config:
Payment Risk Gate: Orders with risk_score > 60 are blocked and escalated immediately.
Autonomous Refund Cap: Auto-refunds capped at ₹1,000 INR. Over-limit refunds are escalated.
Fulfillment Staleness Threshold: Warehouse requeue requires days_since_last_update >= 3.
Oversold Stock Protection: Stock release blocked if stock_on_hand === 0.
Neon PostgreSQL Database & Dual Store Architecture:
Cloud Persistence: Uses @neondatabase/serverless to store all 6 normalized order tables, audit_log, and order_analysis_log in a Neon DB instance when DATABASE_URL is set.
Local Dev Fallback: Gracefully falls back to an in-memory store when running locally without a database connection.
Durable Auditing & Order Analysis Activity Logging:
Audit Log: Durably records every resolution attempt (executed vs escalated), policy reason, and actor.
Analysis Log: Records diagnostic runs, evidence snapshots, and safety check evaluations for full operational auditability.
Exposed via MCP resources (commerce://audit/log, commerce://analysis/log) and REST API (/api/audit, /api/analysis).

+-----------------------------------------------------------------------------------+Discovery & Data Fetch (list_orders / search_orders):
The Client LLM searches or fetches raw order signals (payment.payment_status, payment.risk_score, fulfillment.picking_status, inventory.stock_on_hand).
Signal data contains zero pre-baked diagnostic answers.
Dynamic Root Cause Diagnosis (diagnose):
The server inspects raw telemetry dynamically and infers root cause (e.g., missed payment webhook, warehouse bottleneck, oversold flash-sale, fraud risk).
Returns diagnostic evidence snapshot and recommended resolution action.
Pre-Execution Safety & Escalation Gate (evaluate_safety):
Before executing any mutation, safety policies are evaluated in strict order:
Fraud Risk Gate: payment.risk_score > 60 immediately short-circuits execution and marks order as ESCALATED to human fraud team.
Autonomous Refund Cap: Refunds > ₹1,000 INR require human manager escalation.
Fulfillment Staleness Threshold: Warehouse requeue requires elapsed staleness >= 3 days.
Oversold Inventory Gate: Stock release blocked if physical inventory on hand is 0.
Bounded State Mutation & Durable Auditing (execute_resolution):
Allowed Actions: Bounded enum (mark_order_paid_reconcile, refund_duplicate_charge, refund_over_cap, requeue_to_warehouse, release_reserved_stock, resync_shipping_address).
If safety passes, state is updated (paid, requeued, refunded, etc.) and an executed entry is logged.
If safety fails or human review is required, status becomes escalated and an escalated entry is logged.
All events append to both commerce://audit/log and commerce://analysis/log (or Neon DB tables).

--method resources/read --uri commerce://analysis/logThe diagnose() tool is implemented as a deterministic, rule-based engine rather than having the LLM reason freely over raw order data each time:
How it works: The tool evaluates a fixed set of priority rules against raw telemetry fields (payment gateway status, webhook receipt, inventory reservation, staleness, stock levels) and returns the first matching root cause alongside structured evidence. Nothing is pre-labeled in the seed data itself — the conclusion is computed fresh on every call.
Why this design: Root-causing whether an order is stuck and why has one correct answer given the data. Externalizing this into a deterministic engine ensures diagnostic accuracy is reliable, repeatable, and unit-testable, rather than left to non-deterministic LLM judgment each time.
LLM's Role: The Client LLM's role is to decide what to do with the diagnosis (call evaluate_safety, execute_resolution, or report back), not to re-derive the root cause itself.
Scenarios Covered:
Missed/Dropped Payment Webhook (mark_order_paid_reconcile)
Stalled Warehouse Fulfillment (requeue_to_warehouse)
Over-Cap Refund Request (refund_over_cap)
Oversold Flash-Sale Inventory (release_reserved_stock)
Healthy Control Case (recommended_action: null)
Rule Scalability: This hardcoded rule-based approach covers the 5 seeded e-commerce scenarios well, but would not scale cleanly to hundreds of complex edge cases as-is.
Production Architecture Next Steps: A full enterprise production version would:
Externalize rules into a data-driven rule engine table (e.g. JSON-Logic / Drools).
Incorporate an LLM-assisted fallback mechanism for unmapped operational anomalies rather than defaulting strictly to "healthy", allowing novel edge cases to be dynamically flagged for human triage.
