dns_record_types
AI agents call dns_record_types to retrieve information from DoH MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
DNS record type enumeration is a read-only operation that retrieves reference data about DNS record formats without querying live DNS data or modifying anything. No side effects are expected. Confidence is reduced to 0.7 rather than higher because the tool description is empty, leaving some ambiguity, though context from the server purpose and sibling tools strongly indicates a read operation.
From the tool's definition Tool name 'dns_record_types' on a DoH MCP server strongly suggests it retrieves or enumerates DNS record types (A, AAAA, MX, TXT, etc.).
Attacks that exploit this kind of access
dns_record_types. It is categorised as a Read tool in the DoH MCP Server MCP Server, which means it retrieves data without modifying state.
Register the DoH MCP Server MCP server in PolicyLayer and add a rule for dns_record_types: 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 DoH MCP Server. Nothing to install.
dns_record_types 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_record_types 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_record_types. 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_record_types is provided by the DoH MCP Server MCP server (randark-jmt/doh-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
