search_aliases
AI agents call search_aliases to retrieve information from pfSense Enhanced MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'search_' prefix strongly suggests data retrieval without modification. Within a pfSense firewall context, searching aliases (likely IP/network aliases used in rules) would be a read operation to retrieve configuration information. The lack of description lowers confidence slightly, but the tool name and sibling tools provide sufficient evidence for low-severity read classification.
From the tool's definition Tool name 'search_aliases' combined with context of other tools on the server (analyze_blocked_traffic, find_blocked_rules, find_interfaces_by_status, find_object_by_field) indicates a query/search operation.
Attacks that exploit this kind of access
search_aliases. It is categorised as a Read tool in the pfSense Enhanced MCP Server MCP Server, which means it retrieves data without modifying state.
Register the pfSense Enhanced MCP Server MCP server in PolicyLayer and add a rule for search_aliases: 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 pfSense Enhanced MCP Server. Nothing to install.
search_aliases 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 search_aliases 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 search_aliases. 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.
search_aliases is provided by the pfSense Enhanced MCP Server MCP server (mmaxwellcb/pfsesen_mcp_2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
