Get promotion details by ID
AI agents call vtex_get_promotion to retrieve information from MCP VTEX Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing promotion information from the VTEX platform. It performs a read-only lookup operation by promotion ID, returning data without modifying, creating, deleting, or executing any actions. There is no financial impact, no code execution, and no irreversible changes. The minimal blast radius of an accidental misuse would be exposure of promotion details already stored in the system.
From the tool's definition Tool name 'vtex_get_promotion' and description 'Get promotion details by ID' clearly indicate a retrieval operation with no side effects.
