Documentation

What is MCP Server?

The Model Context Protocol (MCP) is a standardized way to connect language models (like ChatGPT) with external tools, APIs, and systems. It allows an AI model to make structured tool calls — similar to calling functions — during a conversation.

The MCP Server acts as a bridge between the language model and your application logic. It exposes a list of tools (like “search for a product” or “create an order”) and executes them in response to requests from the AI.

This plugin integrates Sylius with an MCP Server, enabling AI agents to interact with your store (e.g., search products, check prices, start checkout).

We use the official symfony/mcp-bundle to provide the MCP server runtime.
