add_product · Product Agent MCP Server MCP: Risk & Policy

WHAT IT DOES

What add_product does on Product Agent MCP Server

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

WHY IT NEEDS A POLICY

Why add_product needs a policy

This tool creates and persists new product records in the database. While reversible (the record can be updated or deleted later), it modifies the database state and could be misused to add invalid, duplicate, or malicious product entries that affect the integrity of product data. The medium severity reflects the moderate blast radius—corrupted product data impacts business operations but is correctable.

From the tool's definition Tool name 'add_product' and description 'Добавить продукт и вернуть созданную запись' (Add product and return created record) indicate creation of new data in the product database.
