Retrieves a list of user roles.\r\n\r\n\r\n<h4>Required permission(s):</h4><span class=
AI agents call list_userroles to retrieve information from Wpm Mcp Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only retrieval of user role data. It queries existing information without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an attacker gains visibility into role definitions but cannot alter permissions, execute code, or cause financial impact.
From the tool's definition Tool name is 'list_userroles' and description states 'Retrieves a list of user roles' — a query operation with no side effects.
Attacks that exploit this kind of access
Retrieves a list of user roles.\r\n\r\n\r\n<h4>Required permission(s):</h4><span class=. It is categorised as a Read tool in the Wpm Mcp Server MCP Server, which means it retrieves data without modifying state.
Register the Wpm Mcp Server MCP server in PolicyLayer and add a rule for list_userroles: 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 Wpm Mcp Server. Nothing to install.
list_userroles 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_userroles 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_userroles. 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_userroles is provided by the Wpm Mcp Server MCP server (wpm-mcp-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
