query_srv_record
AI agents call query_srv_record to retrieve information from DNS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves DNS SRV records, which is a read-only DNS query operation. SRV (Service) records are standard DNS lookups used to discover services on a network. The operation has no side effects, does not modify data, and cannot cause harm beyond potential information disclosure of publicly available DNS data.
From the tool's definition Tool name 'query_srv_record' indicates DNS record querying. Server description states it 'enables querying all types of DNS records, including A, AAAA, MX, TXT, NS, CNAME, SOA, PTR, SRV, CAA, and DNSSEC checks.' SRV records are DNS lookup queries with no side…

query_srv_record. It is categorised as a Read tool in the DNS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the DNS MCP Server MCP server in PolicyLayer and add a rule for query_srv_record: 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 DNS MCP Server. Nothing to install.
query_srv_record 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 query_srv_record 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 query_srv_record. 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.
query_srv_record is provided by the DNS MCP Server MCP server (stanibaj/dns-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
query_srv_record is one line of DNS MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
