WHAT IT DOES

What update_named_semantic_metadata_for_tensor does on Tensorus MCP

AI agents use update_named_semantic_metadata_for_tensor to create or update resources in Tensorus MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tensorus MCP environment.

WHY IT NEEDS A POLICY
