AI agents call search_sitters to retrieve information from Rover MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the Rover marketplace to retrieve sitter information. It performs no writes, modifications, executions, deletions, or financial transactions. It is a straightforward read operation comparable to a search or list function. The low severity reflects minimal blast radius if misused — an agent could perform excessive searches but cannot cause harm to data or finances.
From the tool's definition Tool description states it 'Search for pet sitters' and 'Returns a list of available sitters with ratings and pricing' — pure information retrieval with no side effects or modifications.
