Usage

Smart Message Delivery

Mac Messages MCP automatically handles message delivery across different platforms:

• iMessage Users (iPhone, iPad, Mac): Messages sent via iMessage
• Android Users: Messages automatically fall back to SMS/RCS
• Mixed Groups: Optimal delivery method chosen per recipient

# Send to iPhone user - uses iMessage
send_message("+1234567890", "Hey! This goes via iMessage")

# Send to Android user - automatically uses SMS
send_message("+1987654321", "Hey! This goes via SMS") 

# Check delivery method before sending
check_imessage_availability("+1234567890")  # Returns availability status

As a Module

from mac_messages_mcp import get_recent_messages, send_message

# Get recent messages
messages = get_recent_messages(hours=48)
print(messages)

# Send a message (automatically chooses iMessage or SMS)
result = send_message(recipient="+1234567890", message="Hello from Mac Messages MCP!")
print(result)  # Shows whether sent via iMessage or SMS

As a Command-Line Tool

# Run the MCP server directly
mac-messages-mcp
