AI agents call list_internet_gateways to retrieve information from Oci without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of network infrastructure metadata. It lists existing internet gateways attached to a Virtual Cloud Network (VCN), which is a data retrieval operation with no side effects, no code execution, and no data modification. The blast radius of misuse is limited to information disclosure of network topology.
From the tool's definition Tool name 'list_internet_gateways' and description 'List internet gateways attached to a VCN' indicate a query operation that retrieves and enumerates network resource metadata without modification or execution of commands.
Attacks that exploit this kind of access
List internet gateways attached to a VCN. It is categorised as a Read tool in the Oci MCP Server, which means it retrieves data without modifying state.
Register the Oci MCP server in PolicyLayer and add a rule for list_internet_gateways: 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 Oci. Nothing to install.
list_internet_gateways 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_internet_gateways 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_internet_gateways. 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_internet_gateways is provided by the Oci MCP server (sauryadas/oci-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
