Agent Teams

A TypeScript CLI tool that enables AI agents and humans to interact with Microsoft Teams through a simple command interface. Features seamless token extraction from the Teams desktop app and multi-team support.

TOKEN EXPIRY WARNING

CRITICAL: Microsoft Teams tokens expire in 60-90 minutes! Unlike Discord/Slack, Teams tokens have a short lifespan. You MUST:

1. Check token validity before operations
2. Re-extract credentials when tokens expire
3. Handle 401 Unauthorized errors gracefully

# Always check auth status first
agent-teams auth status

# If expired, re-extract
agent-teams auth extract

Quick Start

# Extract credentials from Teams desktop app (zero-config)
agent-teams auth extract

# Get team snapshot
agent-teams snapshot

# Send a message
agent-teams message send <channel-id> "Hello from AI agent!"

# List channels
agent-teams channel list

Authentication

Seamless Token Extraction

agent-teams automatically extracts your Teams credentials from the desktop app:

# Just run this - no manual token copying needed
agent-teams auth extract

# Use --debug for troubleshooting
agent-teams auth extract --debug

This command:

• Auto-detects your platform (macOS/Linux/Windows)
• Extracts skypetoken_asm from Teams desktop app’s Cookies SQLite database
• Validates token against Teams API before saving
• Discovers ALL joined teams
• Stores credentials securely in ~/.config/agent-messenger/

Multi-Team Support

# List all available teams
agent-teams team list

# Switch to a different team
agent-teams team switch <team-id>

# Show current team
agent-teams team current

# Check auth status (includes token expiry info)
agent-teams auth status

agent-teams snapshot --limit 10

Returns JSON with:

• Team metadata (id, name)
• Channels (id, name, type, description)
• Recent messages (id, content, author, timestamp)
• Members (id, displayName, email)

Output Format

JSON (Default)

All commands output JSON by default for AI consumption:

{
  "id": "19:abc123@thread.tacv2",
  "content": "Hello world",
  "author": "John Doe",
  "timestamp": "2024-01-15T10:30:00.000Z"
}

Pretty (Human-Readable)

Use --pretty flag for formatted output:

agent-teams channel list --pretty

Key Differences from Discord/Slack

Important: Teams uses UUID-style channel IDs (like 19:abc123@thread.tacv2). You cannot use channel names directly – use channel list to find IDs first.

Common Patterns

See references/common-patterns.md for typical AI agent workflows.

Templates

See templates/ directory for runnable examples:

• post-message.sh – Send messages with error handling
• monitor-channel.sh – Monitor channel for new messages (with token refresh)
• team-summary.sh – Generate team summary

Error Handling

All commands return consistent error format:

{
  "error": "Not authenticated. Run \"auth extract\" first."
}

Common errors:

• Not authenticated: No valid token – run auth extract
• Token expired: Token has expired (60-90 min limit) – run auth extract again
• No current team set: Run team switch <id> first
• Message not found: Invalid message ID
• Channel not found: Invalid channel ID
• 401 Unauthorized: Token expired – re-authenticate immediately

Configuration

Credentials stored in: ~/.config/agent-messenger/teams-credentials.json

Format:

{
  "token": "skypetoken_asm_value_here",
  "token_extracted_at": "2024-01-15T10:00:00.000Z",
  "current_team": "team-uuid-here",
  "teams": {
    "team-uuid-here": {
      "team_id": "team-uuid-here",
      "team_name": "My Team"
    }
  }
}

Security: File permissions set to 0600 (owner read/write only)

Limitations

• No real-time events / WebSocket connection
• No voice/video channel support
• No team management (create/delete channels, roles)
• No meeting support
• No webhook support
• Plain text messages only (no adaptive cards in v1)
• User tokens only (no app tokens)
• Token expires in 60-90 minutes – must re-authenticate frequently
