Update an existing CDV role by its numeric ID.
AI agents use update_role to create or update resources in Cloudera Data Visualization MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cloudera Data Visualization MCP Server environment.
This tool modifies role configuration, which affects authorization policies and user access controls across the Cloudera Data Visualization platform. While reversible (thus not Destructive), unauthorized role updates could grant excessive permissions or lock out legitimate users, making the blast radius significant.
From the tool's definition Tool name is 'update_role' and description states 'Update an existing CDV role'. The verb 'update' indicates modification of existing data. Roles typically control access and permissions in enterprise systems.
Attacks that exploit this kind of access
Update an existing CDV role by its numeric ID. It is categorised as a Write tool in the Cloudera Data Visualization MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Cloudera Data Visualization MCP Server MCP server in PolicyLayer and add a rule for update_role: 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.
update_role is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_role 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 update_role. 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.
update_role 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.
update_role 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.
