Retrieves details about a forum post including its messages
AI agents call discord_get_forum_post to retrieve information from MCP-Discord without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns data about an existing forum post. It performs no write, delete, execute, or financial operations. The verb 'retrieves' and the read-only nature of fetching post details clearly place it in the Read category with low severity, as misuse would only expose information without causing damage or unintended actions.
From the tool's definition Tool name is 'discord_get_forum_post' and description states it 'Retrieves details about a forum post including its messages' — retrieval with no modification or side effects.
