Get information about creative update limitations in Meta
AI agents call update_creative to retrieve information from Meta Marketing API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the name 'update_creative' suggesting a write operation, the description explicitly states it retrieves information about update limitations, not that it performs updates. This is a read operation. Confidence is reduced because the name conflicts with the description, suggesting the description may be incomplete or misleading.
