AI agents call perform_security_assessment 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 security posture assessment through heuristic checks without modifying, executing, or deleting any resources. It retrieves and analyzes security metadata to identify potential vulnerabilities, which is a read-only operation with no side effects.
From the tool's definition Tool description explicitly states 'Read-only heuristics' and mentions 'Basic security posture checks (public IPs, wide-open rules)' which are passive scanning/inspection operations.
Attacks that exploit this kind of access
Basic security posture checks (public IPs, wide-open rules). Read-only heuristics. 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 perform_security_assessment: 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.
perform_security_assessment 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 perform_security_assessment 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 perform_security_assessment. 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.
perform_security_assessment 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.
