Get search suggestions/autocomplete for a search term using session-based authentication.
AI agents call mcp__willys_search_suggestions 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 autocomplete suggestions for search queries. It performs a read-only operation that queries a search index or suggestion database and returns results to the user without creating, modifying, deleting, or executing any actions. The session-based authentication is a security mechanism but does not change the read-only nature of the operation.
From the tool's definition Tool name indicates 'search_suggestions' and description states 'Get search suggestions/autocomplete' - retrieval operations with no side effects. No modification, deletion, or execution of external operations.
