update_item · ConsignCloud MCP Server MCP: Risk & Policy

WHAT IT DOES

What update_item does on ConsignCloud MCP Server

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

WHY IT NEEDS A POLICY

Why update_item needs a policy

This tool modifies inventory item records but does not permanently delete or destroy them (which would be Destructive), nor does it execute arbitrary code or trigger external operations (which would be Execute). It creates or modifies data reversibly, fitting the Write category. Severity is medium because inventory data is important to business operations, but the impact is localized to a single item and reversible.

From the tool's definition Tool name 'update_item' and description 'Update an existing inventory item' directly indicate modification of existing data. The verb 'update' is a classic write operation that changes data reversibly.
