Officeclaw

OfficeClaw: Microsoft Graph API Integration

Connect your OpenClaw agent to personal Microsoft accounts (Outlook.com, Hotmail, Live) to manage email, calendar, and tasks through the Microsoft Graph API.

Installation

Install from PyPI:

pip install officeclaw

Or with uv:

uv pip install officeclaw

Verify installation:

officeclaw --version

Setup (One-Time)

Quick start: OfficeClaw ships with a default app registration — just run officeclaw auth login and go. No Azure setup needed.

Advanced: Want full control? Create your own Azure App Registration (free, ~5 minutes) and set OFFICECLAW_CLIENT_ID in your .env. See Microsoft's guide or follow the steps below.

1. Create an Azure App Registration

1. Go to entra.microsoft.com → App registrations → New registration
2. Name: officeclaw (or anything you like)
3. Supported account types: Personal Microsoft accounts only
4. Redirect URI: leave blank (not needed for device code flow)
5. Click Register
6. Copy the Application (client) ID — this is your OFFICECLAW_CLIENT_ID
7. Go to Authentication → Advanced settings → Allow public client flows → Yes → Save
8. Go to API permissions → Add permission → Microsoft Graph → Delegated permissions. Choose based on your needs:

Read-only (safest):

• Mail.Read, Calendars.Read, Tasks.ReadWrite*

Full access (all features including send/delete):

• Mail.Read, Mail.ReadWrite, Mail.Send
• Calendars.Read, Calendars.ReadWrite
• Tasks.ReadWrite

*Tasks.ReadWrite is the minimum available scope for Microsoft To Do — there is no read-only option.

Least privilege: Only grant the permissions you actually need. If you only want to read emails and calendar, skip Mail.ReadWrite, Mail.Send, and Calendars.ReadWrite. OfficeClaw will gracefully error on commands that require missing permissions.

2. Configure Environment

Create a .env file in your skill directory:

OFFICECLAW_CLIENT_ID=your-client-id-here

# Capability gates (disabled by default for safety)
# OFFICECLAW_ENABLE_SEND=true    # Allow sending/replying/forwarding emails
# OFFICECLAW_ENABLE_DELETE=true   # Allow deleting emails, events, and tasks

No client secret needed for device code flow. Write operations (send, delete) are disabled by default — enable only what you need.

3. Authenticate

officeclaw auth login

This displays a URL and code. Open the URL in a browser, enter the code, and sign in with your Microsoft account. Tokens are stored securely in ~/.officeclaw/token_cache.json (permissions 600).

When to Use This Skill

Activate this skill when the user needs to:

Email Operations

• Read emails: "Show me my latest emails", "Find emails from john@example.com"
• Send emails: "Send an email to...", "Reply to the last email from..."
• Manage inbox: "Mark emails as read", "Archive old emails", "Delete emails"

Calendar Operations

• View events: "What's on my calendar today?", "Show meetings this week"
• Create events: "Schedule a meeting with...", "Add dentist appointment on Friday"
• Update events: "Move the 2pm meeting to 3pm", "Cancel tomorrow's standup"

Task Management

• List tasks: "What's on my to-do list?", "Show incomplete tasks"
• Create tasks: "Add 'buy groceries' to my tasks", "Create a task to review report"
• Complete tasks: "Mark 'finish proposal' as done", "Complete all shopping tasks"

Available Commands

officeclaw mail archive <message-id>           # Archive a message
officeclaw mail mark-read <message-id>         # Mark as read
officeclaw --json mail list                    # JSON output for parsing

Calendar Commands

officeclaw calendar list --start 2026-02-01 --end 2026-02-28
officeclaw calendar create \
  --subject "Team Meeting" \
  --start "2026-02-15T10:00:00" \
  --end "2026-02-15T11:00:00" \
  --location "Conference Room"
officeclaw calendar get <event-id>
officeclaw calendar update <event-id> --subject "Updated Meeting"
officeclaw calendar delete <event-id>
officeclaw --json calendar list --start 2026-02-01 --end 2026-02-28

Task Commands

officeclaw tasks list-lists                              # List task lists
officeclaw tasks list --list-id <list-id>                # List tasks
officeclaw tasks list --list-id <list-id> --status active  # Active tasks only
officeclaw tasks create --list-id <list-id> --title "Complete report" --due-date "2026-02-20"
officeclaw tasks complete --list-id <list-id> --task-id <task-id>
officeclaw tasks reopen --list-id <list-id> --task-id <task-id>

Output Format

Use --json flag for structured JSON output:

officeclaw --json mail list

Returns:

{
  "status": "success",
  "data": [
    {
      "id": "AAMkADEzN...",
      "subject": "Meeting Notes",
      "from": {"emailAddress": {"address": "sender@example.com"}},
      "receivedDateTime": "2026-02-12T10:30:00Z",
      "isRead": false
    }
  ]
}

Error Handling

Common errors and solutions:

Guidelines for Agents

When using this skill:

1. Confirm destructive actions: Ask before deleting or sending
2. Summarize results: Don't show raw JSON, provide summaries
3. Handle errors gracefully: Guide user through re-authentication
4. Respect privacy: Don't log email content
5. Use JSON mode: For programmatic parsing, use --json flag
6. Batch operations: Process multiple items efficiently

Security & Privacy

• Write operations disabled by default: Send, reply, forward, and delete are all blocked unless explicitly enabled via OFFICECLAW_ENABLE_SEND and OFFICECLAW_ENABLE_DELETE environment variables. This prevents accidental or unauthorised write actions.
• No client secret required: Uses device code flow (public client) by default
• Least-privilege permissions: You choose which Graph API scopes to grant — read-only is sufficient for most use cases. See the setup guide above.
• Tokens stored securely: ~/.officeclaw/token_cache.json with 600 file permissions
• No data storage: OfficeClaw passes data through, never stores email/calendar content
• No telemetry: No usage data collected
• Your own Azure app: Each user creates their own Azure app registration with their own client ID — no shared credentials

Troubleshooting

If the skill isn't working:

1. Check authentication: Run officeclaw auth status
2. Re-authenticate: Run officeclaw auth login
3. Verify network: Ensure graph.microsoft.com is reachable
4. Check environment: Verify OFFICECLAW_CLIENT_ID is set in .env
