Search indexed documents by keyword or phrase using TF-IDF ranking.
AI agents call search_documents to retrieve information from MCP Demo - Document Search Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing indexed documents and returns results based on keyword matching. It has no ability to create, modify, delete, or execute code. The operation is non-destructive and read-only, with minimal security risk—worst case being information disclosure of documents the user already has access to.
From the tool's definition Tool description states it 'Search[es] indexed documents by keyword or phrase' with 'TF-IDF ranking'. The verb 'search' and the read-only nature of querying indexed documents with no modification capability indicate this is a retrieval operation.
