List KMS vaults.
AI agents call list_vaults 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 retrieves information about existing OCI KMS vaults. It performs no creation, modification, deletion, or code execution. While KMS vaults manage encryption keys (sensitive), merely listing them is a read operation with minimal blast radius—it returns metadata about vault objects without accessing their contents or enabling key operations. Categorized as Read with low severity.
From the tool's definition Tool name 'list_vaults' and description 'List KMS vaults' indicate a query/retrieval operation with no side effects. The verb 'list' is a classic read-only operation that enumerates resources without modification.
Attacks that exploit this kind of access
List KMS vaults. 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_vaults: 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_vaults 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_vaults 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_vaults. 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_vaults 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.
