Teams Notifications

MCP Server

URL: https://mcp.microsoft365.com/mcp. Auth: OAuth 2.0 (Azure AD, scopes: Chat.ReadWrite, ChannelMessage.Send).

MCP Tools

Covers chats, messages, channels, members, and settings.

Example MCP calls

Post a progress update:

// tool: teams_messages_create
{ "channel_id": "channel-xyz", "body": "🔄 TAS-42 — In progress — implementing unit tests\nFiles: 3 (PriceFilter.tsx, test, index)" }

Read replies in thread:

// tool: teams_messages_list_replies
{ "channel_id": "channel-xyz", "thread_id": "thread-abc", "limit": 50 }

Human-in-the-Loop Approval

1. Post approval request — verify the response confirms message_id:

// tool: teams_messages_create
{ "channel_id": "channel-xyz", "body": "⏳ Approval Required\nTask: TAS-42 — Run migration on production\nReply: Approve or Reject", "threading": { "start_thread": true } }
// → { "message_id": "msg-123", "thread_id": "thread-abc" }

If post fails: retry once; if still failing, fall back to asking in chat only.

2. Poll for response (5s interval, 5 min timeout):

const replies = await teams_messages_list_replies({ channel_id: channelId, thread_id: threadId, limit: 50 });
for (const r of replies || []) {
  if (/\b(approve|yes)\b/i.test(r.body)) return 'approved';
  if (/\b(reject|no)\b/i.test(r.body)) return 'rejected';
}
// Retry after 5s; timeout after 5 min → post escalation message

3. Acknowledge — Post confirmation of the action taken and close the thread.

Channel & Chat Conventions

Threading Rules

• Always reply in threads; one thread per task; include tracker issue ID in every message.

Message Formatting

Adaptive Cards and advanced payloads

For large Adaptive Card JSON, rate limits, and security considerations see REFERENCE.md. Use Adaptive Cards when structured inputs or buttons are required; otherwise post a simple threaded message.
