Post-Stocky Shopify replenishment, MOQ Purchase Order generator, and 3-way invoice match MCP.

The publisher's own server: QuickBooks Connector by Meridian

Overview

AI-generated overview

Local MCP server that computes Shopify inventory replenishment plans, builds vendor purchase orders with landed costs, and runs 3-way invoice matching.

What you can do
  • Calculate replenishment plans: ABC classes, stockout-adjusted velocity, safety stock, reorder points and recommended order units per SKU
  • Build vendor purchase orders: carton rounding, MOQs, supplier minimums, US tariff and freight landed costs, Open-to-Buy cash caps, plus Shopify draft PO and POS transfer CSVs
  • Reconcile purchase orders against receiving counts and supplier invoices, with verified payable amounts, QuickBooks and Xero bill CSVs and a debit memo email
  • Rebuild supplier profiles, lead times and carton multiples from a pasted Stocky purchase order CSV export
When to use it
Useful for Shopify merchants and US wholesalers who lost Stocky's purchasing logic and want an assistant to run reorder math, draft vendor purchase orders, or audit supplier invoices. Demo mode and CSV input let you evaluate it without store credentials.
Requirements
Runs locally as an npm package via npx (Node.js required) over stdio, or optionally as a local Streamable HTTP endpoint. No credentials needed in demo or CSV mode; live Shopify mode needs SHOPIFY_STORE_DOMAIN and a read-only SHOPIFY_ACCESS_TOKEN, and paid tiers need PO_PILOT_LICENSE_KEY.
Before you install
Live store mode requires a Shopify Admin access token (SHOPIFY_ACCESS_TOKEN) and a license key (PO_PILOT_LICENSE_KEY) as environment variables. The free sandbox is capped at 25 SKUs and 15 invoice SKUs per call; unlimited use, live Shopify sync and the n8n workflows require paid one-time licenses or a cloud subscription. Tools are described as read-only and produce CSVs and emails rather than sending them.

Installation

In SourceWeft

  1. Open Po Pilot Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Post-Stocky replenishment math, Open-to-Buy & US tariff landed-cost Purchase Orders, Shopify POS barcode Transfer CSVs, Stocky CSV supplier recovery, and Accounts Payable 3-way invoice matching (with QuickBooks Online & Xero Bill CSV exports) for Shopify merchants and US wholesalers.

Shopify retired Stocky on August 31, 2026. Native Shopify Admin stores inventory counts and draft PO records, yet drops the purchasing logic merchants relied on: reorder point calculation, carton/case-pack rounding, vendor minimum order thresholds, supplier export, and invoice discrepancy checks. Meanwhile, Shopify's official Storefront and UCP MCP endpoints (catalog, cart, checkout, policies) serve front-office shoppers only.

po-pilot-mcp connects Claude Desktop, Claude Code, Cursor, or n8n to four deterministic back-office purchasing tools. Every tool runs locally or over Streamable HTTP with zero required credentials in demo_mode or CSV mode, and optionally connects to live Shopify Admin GraphQL (2026-04) when read-only store credentials are supplied.


Setup in Under 60 Seconds

Option A: Zero-Key Quickstart (Claude Desktop / Cursor)

Add this block to claude_desktop_config.json or .cursor/mcp.json (exact version pin recommended for reproducible deployments):

Option B: Claude Code CLI (One Command)

bash
claude mcp add po-pilot -- npx -y [email protected]

Option C: Live Shopify Store Mode (Optional Read-Only Admin Token)

Create a custom app in Shopify Admin -> Settings -> Apps and sales channels -> Develop apps with three read-only scopes: read_products, read_inventory, and read_orders.

json
{  "mcpServers": {    "po-pilot": {      "command": "npx",      "args": ["-y", "[email protected]"],      "env": {        "PO_PILOT_LICENSE_KEY": "your_polar_or_pop1_license_key",        "SHOPIFY_STORE_DOMAIN": "your-store.myshopify.com",        "SHOPIFY_ACCESS_TOKEN": "shpat_your_read_only_token"      }    }  }}

Option D: Remote Streamable HTTP (n8n / Cloud Gateways / MCPize)

bash
npx -y [email protected] --http# Listening on http://0.0.0.0:8080/mcp (Health check: GET /health)

3 Copy-Paste Prompts (Test Immediately)

Prompt 1: Monday Morning Vendor PO Run + Landed Cost + POS Barcode CSV (Zero API Keys Needed)

text
Use po-pilot to run `build_supplier_purchase_orders` with `demo_mode: true`, `service_level: "95%"`, and `max_cash_budget_usd: 3800`. Show me:1. Which SKUs are at CRITICAL stockout risk after adjusting for past stockout days,2. True landed unit costs after US import tariffs + freight (and any margin-erosion warnings) plus how Open-to-Buy rationed cartons under my $3,800 cash cap,3. Both the Shopify Admin Draft PO CSV (`SKU,Supplier SKU,Quantity,Cost,Tax %`) and the Shopify POS Inventory Transfer CSV (`SKU,Barcode,Quantity`), and4. The ready-to-send PO emails for each vendor.

Prompt 2: Rescue Un-Exportable Supplier Data from Stocky CSV

text
Shopify Stocky never exported our supplier directory before shutting down. Run `migrate_stocky_csv_snapshot` with `demo_mode: true` (or use the Stocky Purchase Orders CSV I paste below) to reconstruct each vendor's real observed lead time in days, inferred carton pack sizes, latest unit costs, and a ready `supplier_rules` JSON configuration.

Prompt 3: Finance Ops 3-Way Match Audit + QuickBooks/Xero Verified Bill CSV

text
Run `reconcile_po_three_way_match` with `demo_mode: true`. Cross-check our original Purchase Order against warehouse dock receiving counts and the supplier's billed invoice. List every unit-price overcharge, short-shipment billed in full, unapproved surcharge, and freight cap overage, then give me the verified USD amount to pay ($2,386.20), the ready-to-import QuickBooks Online & Xero Bill CSVs (excluding unapproved fees), and the Debit Memo email to send their AR team.

Deterministic Math Under the Hood

  1. Inventory Position (prevents double-ordering while stock is in transit): $$\text{IP} = \text{OnHand} + \text{OnOrder} - \text{Committed} - \text{Backorders}$$
  2. Stockout-Adjusted Daily Velocity (prevents artificially depressed velocity when a bestseller was out of stock for part of the month): $$d = \frac{\text{UnitsSold}}{\max(1,; \text{WindowDays} - \text{StockoutDays})}$$
  3. Demand + Lead-Time Variability Safety Stock: $$\text{SS} = \left\lceil Z \cdot \sqrt{\text{LT} \cdot \sigma_d^2 + d^2 \cdot \sigma_{\text{LT}}^2} \right\rceil$$ where $Z \in {1.04, 1.28, 1.65, 1.96, 2.33}$ for $85%, 90%, 95%, 97.5%, 99%$ cycle service levels.
  4. Periodic Review Order Quantity & Carton Rounding: $$\text{ROP} = \lceil d \cdot \text{LT} + \text{SS} \rceil, \quad S = \lceil d \cdot (\text{LT} + R) + \text{SS} \rceil$$ When $\text{IP} \le \text{ROP}$, raw order need $Q_0 = \max(\text{SKU-MOQ}, S - \text{IP})$ is rounded to carton multiples $\lceil Q_0 / \text{CasePack} \rceil \times \text{CasePack}$. If a vendor PO falls short of min_order_value_usd (such as a $2,200 wholesale minimum or free-freight tier), the engine adds carton increments to the highest-velocity A-class SKU rather than padding slow C-items.

Security, Privacy & Reliability Guarantees

  • Zero Credential Persistence: Tokens passed via SHOPIFY_ACCESS_TOKEN remain in memory for the request lifetime only and are never logged, written to disk, or echoed in error payloads.
  • Read-Only Store Access: Live Shopify GraphQL integration issues POST queries solely for read operations (productVariants and orders) and enforces a strict 15-second AbortSignal timeout.
  • Crash-Proof Error Envelopes: Invalid CSV headers, missing parameters, or network timeouts return structured MCP isError: true responses with remediation steps instead of terminating the stdio process.
  • Zero Known Dependency Advisories: Verified clean under npm audit.
