WHAT IT DOES

What merge_datasets does on MCP Tabular Data Analysis Server

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

WHY IT NEEDS A POLICY

Why merge_datasets needs a policy

The tool name 'merge_datasets' suggests creating new data structures by combining existing datasets, which is a modification operation. Without a detailed description, we cannot determine if the merge is reversible or destructive. In the context of a data analysis server with sibling tools like 'export_data' and 'create_pivot_table', this likely creates derived data structures.

From the tool's definition Tool name 'merge_datasets' indicates a data operation that combines or modifies datasets. No description provided to clarify scope or reversibility.
