Get the list of all available sentiment labels.
AI agents call get_sentiment_labels to retrieve information from KeyNeg 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 configuration or metadata (available sentiment labels) without creating, modifying, deleting, or executing any operations. It has minimal blast radius if misused by an AI agent—it simply returns static enumeration data. Classification as Read is appropriate.
From the tool's definition Tool name 'get_sentiment_labels' and description 'Get the list of all available sentiment labels' indicate a retrieval operation with no side effects. The verb 'Get' and the read-only nature of querying available labels confirm this is a data retrieval action.
