AI agents call get_instance_details 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 is a read operation that queries and returns data about a compute instance without side effects. However, severity is elevated to 'medium' rather than 'low' because the returned information (public IPs, VNIC details) is sensitive infrastructure data that could aid reconnaissance or lateral movement attacks if disclosed to an attacker.
From the tool's definition Tool name and description indicate retrieval of instance details and network information ('Get detailed info for a Compute instance, including VNICs and public IPs'). No modification, deletion, or execution of code is performed—purely informational access.
Attacks that exploit this kind of access
Get detailed info for a Compute instance, including VNICs and public IPs. 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 get_instance_details: 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.
get_instance_details 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 get_instance_details 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 get_instance_details. 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.
get_instance_details is provided by the Oci MCP server (oreo-tech/oci-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_instance_details is one line of Oci's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
