update_dataset · Dataiku DSS MCP Server MCP: Risk & Policy

WHAT IT DOES

What update_dataset does on Dataiku DSS MCP Server

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

WHY IT NEEDS A POLICY

Why update_dataset needs a policy

This tool modifies dataset configurations rather than creating new ones or deleting data. Updates are typically reversible through subsequent modifications, fitting the Write category. Severity is medium because incorrect dataset setting changes could affect data processing pipelines and dependent workflows in a data platform, but the impact is generally recoverable.

From the tool's definition Tool name 'update_dataset' combined with description 'Update dataset settings' indicates modification of existing data configurations. The verb 'update' and reference to 'dataset settings' confirm reversible data alteration.
