Return the agent's OS info.
AI agents call get_agent_os 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.
This tool queries and returns operating system information about a Wazuh agent. It performs a simple data retrieval operation without modifying, deleting, or executing anything. The blast radius of misuse is minimal—an attacker learning OS details could support reconnaissance but causes no direct harm. This is clearly a Read category tool.
From the tool's definition Tool name 'get_agent_os' and description 'Return the agent's OS info' indicate a retrieval operation with no side effects.

Register the Wazuh MCP Server MCP server in PolicyLayer and add a rule for get_agent_os: 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_agent_os 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_agent_os 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_agent_os. 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.
