List all OCI regions.
AI agents call list_regions to retrieve information from OCI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns OCI region metadata. It retrieves read-only information about available regions without creating, modifying, deleting, or executing any operations. The low severity reflects minimal blast radius—listing regions does not affect infrastructure, data, or financial obligations. High confidence stems from explicit 'List' action and lack of any operational capability.
From the tool's definition Tool name 'list_regions' and description 'List all OCI regions' indicate a data retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all OCI regions. It is categorised as a Read tool in the OCI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OCI MCP Server MCP server in PolicyLayer and add a rule for list_regions: 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 MCP Server. Nothing to install.
list_regions 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_regions 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_regions. 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_regions is provided by the OCI MCP Server MCP server (sarthak-pansare/oci-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
