WHAT IT DOES

What reset_dataconnection_cache does on Cloudera Data Visualization MCP Server

AI agents invoke reset_dataconnection_cache to trigger actions in Cloudera Data Visualization MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why reset_dataconnection_cache needs a policy

Resetting a cache is an operational action that triggers an external side effect (clearing cached query results), but it is not purely destructive (cache can be rebuilt) nor does it create or modify persistent data. It executes a system-level operation on the data connection's cache, making Execute the most appropriate category.
