What create_view does on Fusebase MCP Server

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

WHY IT NEEDS A POLICY

Why create_view needs a policy

It is reversible (views can be deleted) and does not irreversibly destroy data or execute arbitrary code. Severity is medium because misconfiguration could affect dashboard functionality and visibility across a workspace, impacting multiple users' ability to access or interpret data correctly.

From the tool's definition Tool description states it "Create[s] a new view within a dashboard (table)" — a reversible creation action that modifies the dashboard structure by adding a new view object with configurable properties (filters, sorts, grouping, column visibility, display…
