Get a list of all available biomes in the database
AI agents call getBiomes 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 metadata (a list of biomes) from the database without modifying, deleting, or executing arbitrary code. It is a straightforward read operation analogous to SELECT queries. The lack of parameters and purely informational purpose confirms it poses minimal risk even if called by an AI agent.
