The article distinguishes between 'tools' and 'resources' within the context of AI model interactions, particularly for systems like MCP. Tools are defined as actions that change state or trigger operations, such as creating or canceling an order. Resources, conversely, are read-only data sources that provide context, like user profiles or product catalogs. Misclassifying these can lead to inefficient, error-prone, and difficult-to-reason-about systems, emphasizing the importance of a clear separation for predictable behavior and improved model decision-making.
