get_node_stats
AI agents call get_node_stats 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 naming convention—'get_' prefix alongside similar read-only getter tools in the Wazuh context—indicates this retrieves monitoring/statistics data without modification or side effects. The empty description reduces confidence slightly, but the semantic context of sibling tools and the server's stated purpose of 'security analysis' and 'system monitoring' supports classification as a read operation.
From the tool's definition Tool name 'get_node_stats' indicates retrieval of node statistics; consistent with sibling tools like 'get_agent_component_stats', 'get_agent_daemon_stats', 'get_agent_hardware', and 'get_agent_hotfixes' which are all read-only getters.

get_node_stats. It is categorised as a Read tool in the Wazuh MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Wazuh MCP Server MCP server in PolicyLayer and add a rule for get_node_stats: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Wazuh MCP Server. Nothing to install.
get_node_stats is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_node_stats rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_node_stats. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_node_stats is provided by the Wazuh MCP Server MCP server (rayasatriatama/wazuh-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
