get_sentiment
AI agents call get_sentiment to retrieve information from FastMCP Document Analyzer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or queries sentiment data from documents without modifying, deleting, or executing external operations. Despite the empty description, the name combined with the server's stated sentiment analysis capability and the pattern of read-only sibling tools (get_document, list_documents, search_documents) strongly indicates this is a Read category tool with low severity.
From the tool's definition Tool name 'get_sentiment' with sibling tools like 'analyze_document', 'extract_keywords', 'calculate_readability', and 'get_document' indicate this is a data retrieval/analysis tool.
