Wolfies Imessage Gateway

iMessage Gateway CLI

The fastest iMessage integration for Claude Code. Direct CLI architecture delivers 19x faster performance than MCP-based alternatives.

Features

• Send Messages: Send iMessages using natural language
• Read Messages: Retrieve message history with contacts or phone numbers
• Smart Contact Lookup: Fuzzy matching for contact names
• Semantic Search (RAG): AI-powered search across iMessages, SuperWhisper, Notes
• Follow-up Detection: Find conversations needing response
• Group Chats: List and read group conversations
• Analytics: Conversation patterns and statistics

Performance

| Operation | Gateway CLI | MCP-based | Speedup | |-----------|-------------|-----------|---------| | List contacts | 40ms | ~763ms | 19x | | Find messages | 43ms | ~763ms | 18x | | Unread messages | 44ms | ~763ms | 17x | | Groups | 61ms | ~763ms | 12x | | Semantic search | 150ms | ~900ms | 6x |

Requirements

• macOS (required - iMessage is macOS only)
• Python 3.9+
• Full Disk Access permission (for reading message history)

Quick Start

1. Clone and Install

git clone https://github.com/yourusername/imessage-gateway.git
cd imessage-gateway
pip install -r requirements.txt

2. Set Up Contacts

# Sync from macOS Contacts (recommended)
python3 scripts/sync_contacts.py

# Or manual setup
cp config/contacts.example.json config/contacts.json
# Edit config/contacts.json with your contacts

3. Grant Permissions

1. Full Disk Access (for reading messages):

• System Settings → Privacy & Security → Full Disk Access
• Add Terminal.app or your Python interpreter

1. Automation (for sending messages):

• Will be requested automatically on first send

4. Test It Out

# List your contacts
python3 gateway/imessage_client.py contacts --json

# Check unread messages
python3 gateway/imessage_client.py unread --json

# Get recent messages
python3 gateway/imessage_client.py recent --limit 20 --json

# Send a message
python3 gateway/imessage_client.py send "John" "Hey, are you free for coffee?"

Why Gateway CLI?

The Gateway CLI architecture bypasses MCP framework overhead entirely:

• Direct execution: Python script runs immediately, no JSON-RPC initialization
• No session startup: MCP servers have ~700-800ms cold start per session
• Smaller footprint: No MCP SDK dependency, simpler codebase
• Same reliability: Uses identical MessagesInterface code for all operations

Claude Code Integration

Using the Skill

The imessage-gateway skill provides natural language access:

/imessage-gateway unread
/imessage-gateway send John "Running late!"
/imessage-gateway search "meeting next week"

Bash Pre-approval

Ensure your settings include:

Bash(python3:*::*)

Configuration

Contact Format

Contacts are stored in config/contacts.json:

{
  "contacts": [
    {
      "name": "John Doe",
      "phone": "14155551234",
      "relationship_type": "friend",
      "notes": "Optional notes"
    }
  ]
}

Phone numbers can be in any format - they're normalized automatically.

Troubleshooting

"Contact not found"

• Run python3 scripts/sync_contacts.py to sync contacts
• Check config/contacts.json exists and has contacts
• Try partial names (e.g., "John" instead of "John Doe")

"Permission denied" reading messages

• Grant Full Disk Access to Terminal/Python
• Restart Terminal after granting permission
• Verify: ls ~/Library/Messages/chat.db

Messages show "[message content not available]"

• Some older messages use a different format
• Attachment-only messages don't have text content
• This is normal for some message types

Development

# Run tests
pytest tests/ -v

# Run performance benchmarks
python3 -m Texting.benchmarks.run_benchmarks

# Sync contacts
python3 scripts/sync_contacts.py

Privacy & Security

• All data stays local on your Mac
• No cloud services for core functionality
• Contacts file is gitignored by default
• Message history accessed read-only
• Optional OpenAI API for semantic search embeddings
