Creates a new post in a Discord forum channel with optional tags
AI agents use discord_create_forum_post to create or update resources in MCP-Discord — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP-Discord environment.
This tool creates new forum posts, which is a reversible write operation. While it modifies Discord's state by adding content, the action is not destructive (posts can be deleted), not financial, and does not execute arbitrary code or external operations.
From the tool's definition The tool name and description explicitly state it 'Creates a new post in a Discord forum channel'. The verb 'Creates' and the action of adding content to a forum channel indicates this is a write operation that adds new data to Discord.

"tools": {
"discord_create_forum_post": {

{
"counter": "discord_create_forum_post_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
