name: teams description: Read and send Microsoft Teams channel and chat messages via teams_* Graph tools.

Microsoft Teams

Purpose

Operate Teams channels and chats through native Microsoft Graph integration tools.

When to Use

• List joined teams, channels, or chats before messaging.
• Read recent channel or chat message history.
• Post a message to a channel or chat (with approval).

When NOT to Use

• Outlook mail or calendar → use outlook.
• OneDrive or SharePoint files → use onedrive / sharepoint.

Workflow

1. teams_verify_connection — confirm Graph access.
2. teams_list_joined_teams → teams_list_channels — resolve team and channel ids.
3. teams_list_channel_messages — read channel history; teams_send_channel_message to post.
4. For DMs: teams_list_chats → teams_list_chat_messages → teams_send_chat_message.
