AI agents call list_rules to retrieve information from Wazuh without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves information about Wazuh detection rules from the SIEM platform. It supports optional filtering by level and group but performs no writes, deletions, or executions. The blast radius is minimal—an agent gaining access could enumerate rules but cannot modify security configurations or trigger alerts.
From the tool's definition Tool name 'list_rules' and description 'List all Wazuh rules' indicate retrieval/query of security rules without modification. No side effects or state changes.
Attacks that exploit this kind of access
List all Wazuh rules with optional level and group filtering. It is categorised as a Read tool in the Wazuh MCP Server, which means it retrieves data without modifying state.
Register the Wazuh MCP server in PolicyLayer and add a rule for list_rules: 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. Nothing to install.
list_rules 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 list_rules 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 list_rules. 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.
list_rules is provided by the Wazuh MCP server (solomonneas/wazuh-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
