Reset the query result cache for a specific CDV dataset. Requires ds_manage permission.
AI agents call reset_dataset_cache to permanently remove resources in Cloudera Data Visualization MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Resetting a cache irreversibly discards cached query results. While the underlying data is not deleted, the cache itself is permanently cleared and cannot be recovered — this is an irreversible action fitting the Destructive category. Misuse could cause performance degradation by forcing expensive cache rebuilds, but the blast radius is moderate since only cached data (not source data) is affected.

Attacks that exploit this kind of access
Reset the query result cache for a specific CDV dataset. Requires ds_manage permission. It is categorised as a Destructive tool in the Cloudera Data Visualization MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Cloudera Data Visualization MCP Server MCP server in PolicyLayer and add a rule for reset_dataset_cache: 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.
reset_dataset_cache is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the reset_dataset_cache 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 reset_dataset_cache. 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.
reset_dataset_cache 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.
