Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This connection provides 12 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
The manual effort of tracking product movement is exhausting.
Right now, checking if you can fulfill an order feels like juggling multiple tabs. You start in the inventory system to see stock levels; then you jump to the CRM just to confirm customer details; next, you open accounting software to verify payment status. Every single handoff requires copy-pasting data and waiting for a human operator.
With this MCP, your agent handles that whole chain of work. You simply ask, 'Can we ship order XYZ?' The system instantly checks the stock using `get_inventory_item`, verifies the customer details via `list_customers`, and confirms payment status by calling `list_invoices`. It gives you a single, definitive yes or no answer.
The Inventory Management Tools Give You Real-Time Visibility
You never have to manually list inventory items anymore. Instead of navigating menus and filters to find product codes, you simply ask your agent to use `list_inventory_items` or run a targeted search using `search_inventory`. These tools pull the metadata directly into your conversation.
It’s not just about seeing the data; it's about trusting it. The underlying Vinkius platform tracks every single API call, providing an uneditable audit trail for every piece of inventory information that flows through the agent.
What your AI can actually do with this
Managing production is messy. You shouldn't need six separate logins just to know if an order can ship or if the books balance. This MCP connects your entire manufacturing workflow—from raw materials to final invoice—into one place.
Need to know how many units are left of a specific product, where they sit in the warehouse, and which batch they belong to? You get that visibility instantly. Need to see if a payment clears or what formula was used to make it? It’s all there. The real value is seeing the entire operational picture: checking stock levels, locating required components, confirming vendor details, and tracking billing records—all through natural conversation.
Because this MCP handles financial and physical goods data together, every single tool call generates a cryptographically signed audit trail in Vinkius. This means you always know exactly who asked for what information and how the numbers flowed, making compliance checks simple. You can use your AI client to manage production recipes, find specific item metadata, or even search through old purchase records—all without leaving your chat window.

Here's how it actually works
The bottom line is you manage complex manufacturing processes by talking to the system instead of clicking through multiple dashboards.
Connect your Wherefour API Key and Secret to Vinkius. Then, select if you're working with test (Sandbox) or live data (Production).
Your AI agent uses the available tools—like get_order or search_inventory—to pull specific records from your ERP.
You get a summarized answer in plain language that combines inventory status, order details, and financial facts into one conversational response.
Who is this actually for?
Operations Managers who are tired of jumping between inventory apps, CRM tools, and accounting software just to answer one question. Quality Control Teams needing absolute proof of material history or Inventory Controllers responsible for keeping the supply chain running smoothly.
Checking multiple production orders (list_orders) against current stock levels and verifying vendor details.
Running a lot traceability check on a specific batch of raw material to ensure it passed all quality inspections before use.
Searching for item details by code (search_inventory) and confirming the storage location list (list_locations).
What Changes When You Connect
Track compliance history: Use list_stock_lots to immediately check the full batch record for any material, satisfying quality control needs instantly.
Cross-check billing data: Run list_invoices alongside get_order details to confirm if a shipment has cleared its payment status.
Know your components: Check available recipes using list_formulas, then cross-reference those ingredients against current stock via search_inventory.
Manage suppliers and buyers: Keep vendor records updated by listing all contacts with list_vendors or checking past spending using list_purchases.
Avoid app switching: Get a combined status report on multiple pending tasks simply by calling list_orders, pulling together both sales and production data.
Build automations: Combine multiple MCPs—for example, linking this Wherefour MCP with a messaging MCP—to automatically notify staff when an order requires manual attention.
See it in action
Need to ship product X, but the customer payment status is unknown.
Instead of logging into accounting and then calling fulfillment, ask your agent: 'Check get_order for PO-123. Is it ready? Also, check list_invoices to confirm if the latest invoice was paid.' The agent gives a single definitive status.
A product failure requires tracing back raw materials.
Ask your agent: 'What is the full lot traceability for batch L-2024? Show me where it came from and what formula was used.' The agent uses list_stock_lots and list_formulas to build a complete audit trail.
A new product needs to be stocked, but the recipe is unclear.
Use the AI to check all available recipes by calling list_formulas, then ask it to compare that list against current stock items using search_inventory so you know what ingredients are immediately usable.
Need a quarterly financial review of spending.
Instead of pulling reports from three different tabs, instruct your agent to pull all purchase records via list_purchases, then cross-reference it with the list of vendors using list_vendors for a holistic spend overview.
The honest tradeoffs
Checking inventory status in chunks
I need to know if Product A is stocked. I'll open the inventory tab, then check the orders tab, and finally look at the purchasing records.
Ask your agent directly: 'Show me the current stock for Product A and list all outstanding sales orders that require it.' This uses search_inventory and list_orders together to give one answer.
Forgetting which tool does what
I need vendor details, so I'll use the search bar. But wait, that was for products.
Use list_vendors directly to get a comprehensive list of all suppliers, or if you just need one specific record, check your contact database using list_customers.
Skipping the batch details
I see 50 units in stock, but I don't know which batch they are from, so the QC team can't sign off.
Don’t just look at item counts. Always run list_stock_lots first to get the specific batch IDs and traceability data before making decisions.
When It Fits, When It Doesn't
Use this MCP if your daily work requires linking physical goods (inventory/lots) with financial transactions (invoices/purchases) or production planning (formulas/orders). You need a single source of truth that spans the entire operational lifecycle. Don't use it, however, if you only need to manage one isolated function—for instance, if your goal is only generating a simple list of customer names, then list_customers alone might suffice without needing the full ERP context. If you are building an automation that needs to check stock levels and simultaneously trigger a billing update, this MCP is necessary because it connects those two domains.
Questions you might have
How do I check if a specific batch of product was handled correctly? (list_stock_lots) +
Use list_stock_lots to see all recorded batches. This tool lets you track the full history, confirming when it arrived and what quality checks were performed on that exact material.
What if I need to check both sales orders and production needs? (list_orders) +
list_orders gives you a unified view of both. You can see which items are reserved for customers (sales) and which materials are needed internally for the next run (production).
Can I find out what raw materials were used to create an item? (list_formulas) +
Yes, call list_formulas. This tool shows all the official recipes. You can then compare those formulas against your current stock levels using other tools.
Does this MCP handle vendor payments or just sales invoices? (list_purchases) +
It handles both sides. list_invoices tracks money owed to you, while list_purchases tracks the records of what you paid out to vendors.
How do I find my Wherefour API Key and Secret? +
Log in to your Wherefour account, navigate to Settings > API, and generate a new set of credentials for your integration.
Can the agent check lot availability for a specific item? +
Yes! Use the list_stock_lots tool to retrieve all available batches and their current quantities for any item in your catalog.
