Teams Hack

One token. Two skills. 90 days of access.

This skill shares the same MSAL refresh token as outlook-hack. Extract once from Teams localStorage, get both email and chat access.

What It Does

  • 💬 Read and send chat messages (1:1 and group)
  • 📢 Read and post to team channels
  • 🔍 Search messages across all of Teams
  • 👥 Browse org directory, check presence status
  • 📅 View calendar with Teams meeting join links
  • 🏢 List joined teams and channels

Quick Start

1. Token Extraction (one-time, ~30 seconds)

Open Microsoft Teams (teams.cloud.microsoft) in Chrome. Attach the tab via OpenClaw browser relay. The agent runs this in the page:

(() => {
  const keys = Object.keys(localStorage).filter(k =>
    k.includes('refreshtoken') || k.includes('RefreshToken')
  );
  const results = keys.map(k => {
    const parsed = JSON.parse(localStorage.getItem(k));
    return { key: k, secret: parsed.secret, client_id: parsed.client_id };
  });
  // Also get tenant ID
  const accountKeys = Object.keys(localStorage).filter(k => {
    try { return JSON.parse(localStorage.getItem(k)).tenantId; } catch { return false; }
  });
  let tenantId = null;
  for (const k of accountKeys) {
    try { tenantId = JSON.parse(localStorage.getItem(k)).tenantId; break; } catch {}
  }
  return { tokens: results, tenantId };
})();

Then store the token:

teams token store --refresh-token <secret> --tenant-id <tenantId>

2. Verify

teams token test

3. Use

teams chats                          # Recent conversations
teams chat <id> --top 10             # Read messages
teams chat-send <id> --message "hi"  # Send message
teams teams                          # List teams
teams channels <teamId>              # List channels
teams search "project update"        # Search everything
teams users --search "Oscar"         # Find people
teams presence                       # Your status
teams calendar --days 3              # Upcoming meetings

How It Works

Same mechanism as the Outlook hack:

  1. Teams stores an MSAL refresh token in localStorage
  2. This token is exchanged for a Graph API access token using Teams' first-party client ID
  3. The client ID (5e3ce6c0-2b1f-4285-8d4b-75ee78787346) has pre-authorized Graph scopes
  4. Token auto-rotates on each use — perpetual access as long as it's used within 90 days

Shared Token Architecture

Both skills read from the same file:

~/.openclaw/credentials/outlook-msal.json

Extract the token once → both outlook and teams CLIs work. If either skill refreshes the token, the other benefits.

CLI Reference

| Command | Description | |---------|-------------| | teams chats | List recent chats with last message preview | | teams chat <id> | Read messages (newest first) | | teams chat-send <id> --message <text> | Send to a chat | | teams teams | List all joined teams | | teams channels <teamId> | List channels in a team | | teams channel <teamId> <channelId> | Read channel messages | | teams channel-send <teamId> <channelId> --message <text> | Post to channel | | teams search "<query>" | Full-text search across messages | | teams users --search <name> | Search org directory | | teams presence | Your availability status | | teams calendar --days 7 | Calendar with meeting links | | teams me | Your profile |

Sibling Skill: Outlook Hack

This skill shares the same MSAL refresh token with outlook-hack. One extraction covers both. Extract the token once → get full chat access (this skill) AND email access (Outlook Hack).

Both skills read and write to the same credentials file:

~/.openclaw/credentials/outlook-msal.json

If either skill refreshes the token, the other benefits automatically.

| Skill | What it does | Send-blocked? | |-------|-------------|---------------| | outlook-hack | Email: read, search, draft, folders, attachments, calendar, contacts | ✅ Cannot send | | teams-hack (this) | Chat: read, send, channels, search, presence, org directory | No (chat sending enabled) |

Architecture

  • Zero external deps — pure Node.js (v22+)
  • Shared credentials — same token file as Outlook
  • Graph API v1.0 — standard Microsoft endpoints
  • Beta fallback — some features use /beta when v1.0 lacks support

The Full Stack

Pair with outlook-hack for email, whatsapp-ultimate for messaging, and jarvis-voice for voice.
