Frequently asked questions

The Model Context Protocol is an open standard for connecting AI applications to external systems. It provides a universal, standardized way for AI agents like Claude or ChatGPT to access data sources, tools, and workflows—similar to how USB-C provides a standardized connection for electronic devices.

Any AI agent that supports the Model Context Protocol can connect to the OneStock MCP server. Anthropic’s Claude and OpenAI’s ChatGPT are among the leading LLM platforms that natively support MCP integrations, enabling seamless access to OneStock retail data.

The OneStock MCP server connects directly to OneStock’s delivery promise engine, which calculates ETAs based on real-time stock positions, logistics constraints, carrier routes, preparation times, and capacity management. This ensures delivery promises shown through AI agents are accurate and reliable.

The OneStock MCP server currently focuses on providing data visibility and enabling actions like reservations, order modifications, and returns. Full transaction processing (checkout and payment) typically occurs through your existing e-commerce platform, with the AI agent guiding the customer through the process.
