list_groups
AI agents call list_groups 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.
The 'list' prefix and absence of write/delete/execute keywords indicate a query operation. Even in an OCI context where listing identity groups could expose organizational structure, this is fundamentally a retrieval operation with no state-changing side effects. The empty description lowers confidence slightly, but the naming convention and server context strongly suggest read-only enumeration.
From the tool's definition Tool name 'list_groups' suggests querying/enumerating groups without modification. No description provided. Sibling tools on server are predominantly Read operations (get_* pattern, cost queries, usage summaries).
Attacks that exploit this kind of access
list_groups. 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_groups: 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_groups 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_groups 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_groups. 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_groups is provided by the OCI MCP Server MCP server (jopsis/mcp-server-oci). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
