AI agents call dns_zone_query to retrieve information from Infra Ops without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves DNS zone data (SOA and NS records) which are informational lookups with no side effects, no code execution, no data modification, and no destructive operations. It is clearly a Read operation with low severity since DNS zone queries are publicly accessible information and pose minimal risk if misused by an AI agent.
From the tool's definition Tool performs 'Query zone information including SOA and NS records' — a read-only operation that retrieves DNS metadata without modifying or executing any changes.
Attacks that exploit this kind of access
Query zone information including SOA and NS records for a domain. It is categorised as a Read tool in the Infra Ops MCP Server, which means it retrieves data without modifying state.
Register the Infra Ops MCP server in PolicyLayer and add a rule for dns_zone_query: 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 Infra Ops. Nothing to install.
dns_zone_query 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 dns_zone_query 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 dns_zone_query. 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.
dns_zone_query is provided by the Infra Ops MCP server (skyvanguard/infra-ops-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
