Problem

When using the message tool's thread-create action on a Discord forum channel that requires tags, the post creation fails because there's no way to specify tags.

Error

A tag is required to create a forum post in this channel

Expected

Add appliedTags or tags parameter to thread-create action to support Discord forum post creation with required tags.

Context

• Discord API supports applied_tags field when creating forum threads
• channel-list already returns available_tags so tag IDs are accessible
• This blocks AI agents from creating forum posts programmatically
