What We Learned Building an MCP Server for Real-Time Inventory

Model Context Protocol (MCP) is quickly becoming our default way to connect language models to real business systems — and our recent inventory assistant project is a good example why.

Instead of writing brittle, one-off integration code every time a model needed fresh inventory data, we built a dedicated MCP server that exposes structured, permissioned access to the client’s ERP. Claude can now query live stock levels, flag discrepancies, and answer natural-language questions from warehouse staff — all without ever touching raw database credentials.

The result is an integration that’s easier to maintain, safer by design, and ready to plug into whichever model the client wants to use next.
