# iMessage Max

An MCP (Model Context Protocol) server for iMessage that lets AI assistants read and search your messages with proper contact resolution.

<!-- mcp-name: io.github.cyberpapiii/imessage-max -->

## Features

- **Media Enrichment** - Images converted to viewable format, video thumbnails extracted, links unfurled with titles
- **Contact Resolution** - See names instead of phone numbers (resolves via macOS Contacts)
- **Participant Lookup** - Find chats by typing names like `find_chat(participants=["Nick", "Andrew"])`
- **Session Grouping** - Messages grouped into conversation sessions with gap detection
- **Token Efficient** - Designed for AI consumption with compact responses and pagination
- **Read-Only Safe** - Only reads from chat.db, never modifies your messages

## Why This Exists

Most iMessage tools expose raw database structures, requiring 3-5 tool calls per user intent. This MCP provides intent-aligned tools that work the way you'd naturally ask questions:

```
"What did Nick and I talk about yesterday?"
→ find_chat(participants=["Nick"]) + get_messages(since="yesterday")

"Show me recent group chats"
→ list_chats(is_group=True)

"Find where we discussed the trip"
→ search(query="trip")
```

## Installation

### Desktop Extension (Recommended)

One-click install with icon support in Claude Desktop:

**Prerequisites:**
1. [UV](https://docs.astral.sh/uv/) must be installed:
   ```bash
   curl -LsSf https://astral.sh/uv/install.sh | sh
   ```
2. Grant **Full Disk Access** to `uvx` (required to read iMessage database):
   - Open **System Settings** → **Privacy & Security** → **Full Disk Access**
   - Click **+** and add `~/.local/bin/uvx` (press Cmd+Shift+G to enter path)

**Install:**
1. Download [`imessage-max.mcpb`](https://github.com/cyberpapiii/imessage-max/releases/latest/download/imessage-max.mcpb)
2. Double-click to install, or drag into Claude Desktop
3. Grant Contacts access when prompted (for name resolution)

**Troubleshooting:** Run the `diagnose` tool to check permissions status.

### From PyPI

```bash
pip install imessage-max
```

### Using UV

```bash
# Install UV if you haven't
curl -LsSf https://astral.sh/uv/install.sh | sh

# Install imessage-max
uv pip install imessage-max
```

### From Source

```bash
pip install git+https://github.com/cyberpapiii/imessage-max.git
```

## Setup

### 1. Grant Permissions

The MCP needs two macOS permissions to work properly:

#### Full Disk Access (Required)
Allows reading `~/Library/Messages/chat.db`

1. Open **System Settings** → **Privacy & Security** → **Full Disk Access**
2. Click **+** and add your terminal app (Terminal.app, iTerm, Warp, etc.)
3. If using Claude Desktop, add the process that runs Python:
   - For UV: Add `/Users/YOU/.local/share/uv/python/` (or find it with `which python`)

#### Contacts Access (Required for name resolution)
Allows resolving phone numbers to contact names

1. Open **System Settings** → **Privacy & Security** → **Contacts**
2. Add the same apps/processes as above
3. **Important:** If using UV, you need to add UV itself (`~/.cargo/bin/uv` or similar)

### 2. Configure Claude Desktop

Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "imessage": {
      "command": "uvx",
      "args": ["imessage-max"]
    }
  }
}
```

Or if installed via pip:

```json
{
  "mcpServers": {
    "imessage": {
      "command": "imessage-max"
    }
  }
}
```

### 3. Restart Claude Desktop

The MCP will request Contacts access on first run if not already granted.

## Tools

### find_chat
Find chats by participants, name, or recent content.

```python
# Find a DM by contact name
find_chat(participants=["Nick"])

# Find a group chat with multiple people
find_chat(participants=["Nick", "Andrew"])

# Find a named group chat
find_chat(name="Family")

# Find chat where you discussed something recently
find_chat(contains_recent="dinner plans")
```

### get_messages
Retrieve messages with flexible filtering. **Returns metadata for media, links are enriched.**

```python
# Get recent messages from a chat
get_messages(chat_id="chat123", limit=50)

# Get messages from the last 24 hours
get_messages(chat_id="chat123", since="24h")

# Get only messages from a specific person
get_messages(chat_id="chat123", from_person="Nick")

# Get messages containing specific text
get_messages(chat_id="chat123", contains="flight")
```

Messages with attachments return metadata (not image content) for performance:

```json
{
  "messages": [{
    "id": "msg_123",
    "text": "Check out this photo!",
    "from": "nick",
    "media": [{
      "type": "image",
      "id": "att123",
      "filename": "IMG_1234.heic",
      "size_bytes": 2457600,
      "dimensions": {"width": 4032, "height": 3024}
    }],
    "links": [{
      "url": "https://instagram.com/p/abc",
      "domain": "instagram.com",
      "title": "Post by @user",
      "description": "Check out this amazing..."
    }]
  }]
}
```

| Media Type | Response |
|------------|----------|
| Images (HEIC/JPEG/PNG) | Metadata only: id, filename, size, dimensions |
| Videos (MOV/MP4) | Metadata: id, filename, duration |
| Audio (voice notes) | Metadata: id, filename, duration |
| Links | Open Graph metadata (title, description, domain), capped at 10 per request |

**To view an image:** Use `get_attachment(attachment_id="att123")` - see below.

### get_attachment
Retrieve full image content by attachment ID. Use after `get_messages` to view specific images.

```python
# Get image optimized for AI analysis (default)
get_attachment(attachment_id="att123")

# Get quick thumbnail preview
get_attachment(attachment_id="att123", variant="thumb")

# Get original full resolution
get_attachment(attachment_id="att123", variant="full")
```

| Variant | Resolution | Use Case | Token Cost |
|---------|------------|----------|------------|
| `vision` (default) | 1568px | AI analysis, reading text in images | ~1,600 tokens |
| `thumb` | 400px | Quick preview, browsing multiple images | ~200 tokens |
| `full` | Original | When you need maximum detail | Varies |

**Example workflow:**
```
1. get_messages(chat_id="chat123") → See media metadata: {"id": "att123", "filename": "photo.heic"}
2. get_attachment(attachment_id="att123") → View the actual image content
```

This metadata-first approach prevents slowdowns when fetching messages with many images.

### list_chats
Browse recent chats with previews.

```python
# List recent chats
list_chats(limit=20)

# List only group chats
list_chats(is_group=True)

# List chats active in the last week
list_chats(since="7d")
```

### search
Full-text search across all messages.

```python
# Search all messages
search(query="dinner")

# Search messages from a specific person
search(query="dinner", from_person="Nick")

# Search with time bounds
search(query="meeting", since="2024-01-01", before="2024-02-01")

# Search only in group chats
search(query="party", is_group=True)
```

### get_context
Get messages surrounding a specific message.

```python
# Get context around a message
get_context(message_id="msg123", before=5, after=10)

# Find message containing text and get context
get_context(chat_id="chat123", contains="that link", before=3, after=5)
```

### get_active_conversations
Find chats with recent back-and-forth activity.

```python
# Find active conversations in the last 24 hours
get_active_conversations(hours=24)

# Find active group conversations
get_active_conversations(is_group=True, min_exchanges=3)
```

### list_attachments
List attachments with metadata.

```python
# List recent attachments
list_attachments(limit=20)

# List images from a specific chat
list_attachments(chat_id="chat123", type="image")

# List attachments from a specific person
list_attachments(from_person="Nick", type="any")
```

### get_unread
Get unread messages or summary. By default, returns unread messages from the last 7 days to match Messages.app behavior.

```python
# Get unread messages (default: last 7 days)
get_unread()

# Get unread from last 24 hours
get_unread(since="24h")

# Get unread from last 14 days
get_unread(since="14d")

# Get ALL historical unread messages (may include stale data)
get_unread(since="all")

# Get unread summary by chat
get_unread(format="summary")

# Get unread from specific chat
get_unread(chat_id="chat123")
```

### send
Send a message (requires Automation permission for Messages.app).

```python
# Send to a contact
send(to="Nick", text="Hey, are we still on for dinner?")

# Send to a group chat
send(chat_id="chat123", text="Running 5 minutes late")
```

### diagnose
Troubleshoot configuration and permission issues.

```python
# Check setup
diagnose()
# Returns: pyobjc_available, contacts_authorized, contacts_loaded count
```

## Troubleshooting

### Contacts showing as phone numbers

Run the `diagnose` tool to check status:

```json
{
  "pyobjc_available": true,
  "contacts_authorized": false,
  "authorization_status": "not_determined"
}
```

**Fix:** Add your Python interpreter or UV to System Settings → Privacy & Security → Contacts.

### "Database not found" error

The MCP can't access `~/Library/Messages/chat.db`.

**Fix:** Add your terminal/Python to System Settings → Privacy & Security → Full Disk Access.

### Empty message previews

Some messages store text in `attributedBody` instead of `text` column. This is handled automatically as of v0.1.0.

### MCP not loading in Claude Desktop

1. Check your config file syntax is valid JSON
2. Ensure the command path is correct
3. Restart Claude Desktop completely (Cmd+Q, not just close window)
