Get full details for a specific flight offer including fare conditions, baggage allowance, and amenities.
AI agents call get_offer_details to retrieve information from Duffel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing flight offer data without creating, modifying, deleting, executing code, or moving money. It is purely informational and read-only, fitting the Read category. The low severity reflects minimal blast radius if misused: an AI agent could only retrieve more flight details than intended, not book flights or commit to purchases.
From the tool's definition get_offer_details retrieves flight offer information including 'fare conditions, baggage allowance, and amenities' — this is a data retrieval operation with no side effects.
