Most frequently triggered WAF rules with severity and description. Use to identify dominant attack patterns.
AI agents call waf_top_rules to retrieve information from WAF 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 reports statistics about WAF rule triggers. It retrieves historical or current data to help understand attack patterns, analogous to viewing logs or metrics. No data is created, modified, deleted, or executed; the assistant gains visibility only.
From the tool's definition Tool description states it returns 'Most frequently triggered WAF rules with severity and description' — a retrieval and analysis function with no modification, deletion, or execution of external commands. The verb 'identify' indicates passive observation.
Attacks that exploit this kind of access
Most frequently triggered WAF rules with severity and description. Use to identify dominant attack patterns. It is categorised as a Read tool in the WAF MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WAF MCP Server MCP server in PolicyLayer and add a rule for waf_top_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 WAF MCP Server. Nothing to install.
waf_top_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 waf_top_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 waf_top_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.
waf_top_rules is provided by the WAF MCP Server MCP server (kratosuae/waf_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
