AI agents call breeds_in_atlas to retrieve information from Sniff Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward data retrieval operation—listing breeds and their frequencies from a genomics atlas. It has no side effects, does not execute code or commands, does not modify or delete data, and does not involve financial transactions. The blast radius of misuse is minimal; returning an incorrect list of breeds poses negligible security risk. This is a classic Read operation.
From the tool's definition Tool name 'breeds_in_atlas' and description 'List all 188 breeds with breed-stratified frequencies in the atlas' indicate a query operation that retrieves and enumerates existing data without modification, deletion, or execution of external operations.
