list_users
AI agents call list_users to retrieve information from Okta MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
List operations retrieve data without modifying, deleting, or executing side effects. While the tool has an empty description (reducing confidence slightly), the name 'list_users' clearly indicates enumeration of user data. Listing users in an identity management context has minimal severity—it reads existing data without triggering provisioning, policy changes, or financial operations.
From the tool's definition Tool name 'list_users' indicates a query/retrieval operation. No description provided, but the function name 'list' is a standard Read operation pattern (retrieve/enumerate data).
Attacks that exploit this kind of access
list_users. It is categorised as a Read tool in the Okta MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Okta MCP Server MCP server in PolicyLayer and add a rule for list_users: 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 Okta MCP Server. Nothing to install.
list_users 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_users 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_users. 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_users is provided by the Okta MCP Server MCP server (pranav-okta/okta-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
