AI agents call facebook_list_pages to retrieve information from Mimi Seed without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that lists data (Facebook pages) without side effects. While it returns sensitive tokens, the tool itself only retrieves information without altering state, making it a Read category risk.
