get_facebook_posts
AI agents call get_facebook_posts to retrieve information from Mcp Metricool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves Facebook post data from the Metricool API with no side effects. It follows the naming pattern of other read-only retrieval tools on the same server (get_best_time_to_post, get_instagram_posts, get_bluesky_posts, etc.).
From the tool's definition Tool name 'get_facebook_posts' and sibling tools (all prefixed with 'get_') indicate data retrieval operations.
