Get current cart contents and pricing information using session-based authentication.
AI agents call mcp__willys_get_cart to retrieve information from Willys MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves shopping cart state and pricing without modifying, deleting, or executing any operations. It uses session-based authentication to query existing data. The blast radius is minimal—an AI agent could only learn about a user's cart contents, which is low-sensitivity information in the context of a grocery shopping application.
From the tool's definition Tool name and description indicate retrieval of data: 'Get current cart contents and pricing information'. The verb 'Get' and the passive data retrieval operation (no modifications, no side effects) align with Read category operations like 'fetch' or 'query'.
