Get a list of monsters with optional filtering, sorting, and pagination
AI agents call getMonsters to retrieve information from RAGmonsters Custom PostgreSQL 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 or queries data from the RAGmonsters dataset with no side effects. The parameters (filtering, sorting, pagination) are typical read-only query operations. No write, delete, execute, or financial capabilities are present. Severity is low because the worst-case misuse is retrieving data the AI shouldn't access, which is a confidentiality concern but has no destructive impact on the system or data.
From the tool's definition Tool name 'getMonsters' and description 'Get a list of monsters with optional filtering, sorting, and pagination' indicate data retrieval with filtering/sorting parameters. No modification, deletion, execution, or financial operations are described.
