Parse a natural-language purchasing intent or draft request into a Sanka Buy request preview. This tool does not create the request; use create_buy_request for writes.
AI agents call preview_buy_request to retrieve information from Sanka MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool explicitly states it does not create a request; it only parses natural-language input into a preview. This is a read/query operation with no side effects. Despite being in a financial context (buy requests), no money is moved or committed.
From the tool's definition 'This tool does not create the request' and 'preview' — it only parses and previews a purchasing intent without committing any action.
