create_view · Sanka MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_view does on Sanka MCP Server

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

WHY IT NEEDS A POLICY

Why create_view needs a policy

This tool creates a new view configuration, which is a reversible modification to the system. It does not execute arbitrary code, delete data, move money, or trigger external operations with unpredictable effects. The severity is medium because creating views could potentially be abused to expose or organize sensitive data in ways the creator did not intend, though the operation itself is reversible through deletion.

From the tool's definition Tool name 'create_view' and description 'Create a saved Sanka view for any supported object' indicate creation of a new data structure. The use of 'create' in the name and 'Create a saved' in the description shows this is a write operation that adds new data.
