List all roles defined in CDV.
AI agents call list_roles to retrieve information from Cloudera Data Visualization 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 operation that queries and returns role data from Cloudera Data Visualization. There are no side effects, no data modification, no code execution, and no destructive or financial implications. It is purely informational retrieval, which is characteristic of the Read category.
From the tool's definition Tool name 'list_roles' and description 'List all roles defined in CDV' indicate a query operation that retrieves and enumerates existing roles without modification or deletion.
Attacks that exploit this kind of access
List all roles defined in CDV. It is categorised as a Read tool in the Cloudera Data Visualization MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cloudera Data Visualization MCP Server MCP server in PolicyLayer and add a rule for list_roles: 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 Cloudera Data Visualization MCP Server. Nothing to install.
list_roles 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_roles 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_roles. 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_roles is provided by the Cloudera Data Visualization MCP Server MCP server (kevintalbert/cdv-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
