“Use Replier to show my Instagram automations and their results over the last 30 days.”

“Use Replier to set up a keyword reply for my latest post. Show me the settings before saving.”

ChatGPT may limit custom MCP apps or write actions by plan and workspace policy. Replier tools also respect your workspace permissions.
