AI agents call porkbun_dns to retrieve information from Access without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves DNS record data for a domain without creating, modifying, or deleting any records. It is a read-only operation that queries existing DNS configuration. The severity is low because reading DNS records does not directly expose sensitive data (DNS records are typically public) and has no side effects.
From the tool's definition Tool description explicitly states 'List all DNS records' and indicates use cases of 'audit DNS configuration or find existing records', which are query/retrieval operations with no modifications.
Attacks that exploit this kind of access
List all DNS records (A, AAAA, CNAME, MX, TXT, NS) for a domain managed in Porkbun. Use this to audit DNS configuration or find existing records before creating new ones. It is categorised as a Read tool in the Access MCP Server, which means it retrieves data without modifying state.
Register the Access MCP server in PolicyLayer and add a rule for porkbun_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 Access. Nothing to install.
porkbun_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 porkbun_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 porkbun_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.
porkbun_dns is provided by the Access MCP server (scottpedia0/access). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
