List all row-level security segments defined in CDV.
AI agents call list_segments 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.
The tool queries and returns existing row-level security segment definitions without creating, modifying, deleting, or executing operations. This is a straightforward read operation that has no side effects on the system or data.
From the tool's definition Tool name is 'list_segments' and description states 'List all row-level security segments defined in CDV' - this is a retrieval operation with no modifications.
Attacks that exploit this kind of access
List all row-level security segments 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_segments: 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_segments 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_segments 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_segments. 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_segments 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.
list_segments is one line of Cloudera Data Visualization MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
