batch_create_items · Skema MCP Server MCP: Risk & Policy

WHAT IT DOES

What batch_create_items does on Skema MCP Server

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

WHY IT NEEDS A POLICY

Why batch_create_items needs a policy

This tool creates multiple collection items in the Skema CMS, which is a reversible write operation. While individual items can be created, the batch nature means a single call could create many items, increasing blast radius if an AI agent misuses it (e.g., spam or unintended bulk creation). However, it remains Write rather than Destructive since creation is reversible via delete operations.

From the tool's definition Tool name 'batch_create_items' and description 'Crée plusieurs items en une seule requête' (Creates multiple items in a single request) indicate creation of data.
