get_rule_groups
AI agents call get_rule_groups to retrieve information from Wazuh MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix strongly suggests data retrieval without side effects. In the context of a Wazuh security platform MCP server, 'get_rule_groups' most likely retrieves security rule groupings or configurations for analysis purposes.
From the tool's definition Tool name 'get_rule_groups' indicates a retrieval operation (get prefix). The description is empty, but sibling tools on this Wazuh MCP Server are predominantly Read-category tools (get_agent_*, count_documents, build_dsql_query for analysis).
