Lists DNS records for a given hosted zone.
AI agents call list_record_sets to retrieve information from AWS 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 record information from AWS Route 53 without creating, modifying, or deleting any records. It is a straightforward data query operation with no side effects. The server is explicitly described as 'read-only,' confirming this tool cannot perform write, execute, or destructive operations.
From the tool's definition Tool name is 'list_record_sets' and description states it 'Lists DNS records for a given hosted zone.' The verb 'Lists' and the read-only nature of querying DNS records without modification indicate retrieval/query capability.
Attacks that exploit this kind of access
Lists DNS records for a given hosted zone. It is categorised as a Read tool in the AWS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS MCP Server MCP server in PolicyLayer and add a rule for list_record_sets: 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 AWS MCP Server. Nothing to install.
list_record_sets 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 list_record_sets 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 list_record_sets. 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.
list_record_sets is provided by the AWS MCP Server MCP server (sergiosediq/aws-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
