AI agents call vrchat_search_groups to retrieve information from VRChat MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search/query operation to retrieve VRChat group data based on search parameters. It has no side effects—it does not create, modify, delete, execute code, or move money.
