What lookup_dns does on GoCreative Agent API
AI agents call lookup_dns to retrieve information from GoCreative Agent API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

domain | string | Yes |
Parameters from the server's own tool schema.
Why lookup_dns is rated Low
DNS lookups are passive reconnaissance that retrieve existing DNS records without side effects or data modification. While DNS information can support reconnaissance for malicious purposes, the tool itself performs no writes, deletes, code execution, or financial transactions. It is purely informational retrieval.
From the tool's definition Tool performs DNS record resolution (A, AAAA, MX, TXT, NS records) with no mutation capability. Description explicitly states use cases are 'security audits, email-deliverability checks, or infra discovery'—all read-only information gathering activities.
Attacks that exploit this kind of access
The rule that runs lookup_dns safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GoCreative Agent API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For lookup_dns, this is the rule to start with:
lookup_dns is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GoCreative Agent API, apply this rule, and every lookup_dns call is checked against it from then on.
Questions about lookup_dns
Resolve DNS records (A, AAAA, MX, TXT, NS) for a domain. Use for security audits, email-deliverability checks, or infra discovery. Example call: {"domain": "github.com"} Cost: $0.005–$0.05 USDC on Base per call. It is categorised as a Read tool in the GoCreative Agent API MCP Server, which means it retrieves data without modifying state.
lookup_dns accepts 1 parameter: domain. Required: domain. The full parameter table on this page comes from the server's own tool schema.
Register the GoCreative Agent API MCP server in PolicyLayer and add a rule for lookup_dns: 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 GoCreative Agent API. Nothing to install.
lookup_dns 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 lookup_dns 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 lookup_dns. 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.
lookup_dns is provided by the GoCreative Agent API MCP server (https://api.gocreativeai.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
