Search for hotels available for Hilton Honors points redemption. Shows points required per night and cash value. Requires being logged in with sufficient points.
AI agents call redeem_points to retrieve information from Mcp Hilton without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Although the tool operates within a financial ecosystem (Hilton Honors points), it only reads/queries available redemption options without executing a points transfer, deducting points, or committing financial obligations. The actual redemption would require a separate transaction tool. This is a search and display function, categorized as Read.
From the tool's definition Tool description states it 'Search[es] for hotels available' and 'Shows points required per night and cash value.' These are query and display operations with no modification of data.
