🎓 Email Management Expert Skill

NEW: This repository now includes a comprehensive Claude Code Skill that teaches Claude how to be an expert email management assistant!

What's a Skill?

A Skill is a Claude Code feature that packages expertise and workflows, teaching Claude not just what it can do (MCP tools), but how to do it effectively. It's like giving Claude a productivity consultant for email management.

MCP + Skill = Intelligent Email Management

• Apple Mail MCP (this server) = The tools (18 email functions)
• Email Management Skill (skill-email-management/) = The expertise (workflows, strategies, best practices)

Together, they create an intelligent assistant that knows both the capabilities and the best ways to use them.

What You Get with the Skill

📋 Complete Workflows:

• Inbox Zero - Achieve and maintain empty inbox
• Daily Email Triage - Process emails quickly (10-15 min)
• Folder Organization - Structure strategies and filing systems
• Advanced Search - Find any email instantly
• Bulk Operations - Clean up and organize efficiently

🧠 Expert Knowledge:

• Industry-standard productivity methods (GTD, Inbox Zero)
• Tool orchestration patterns (when to use which tool)
• Safety-first approaches (backups, limits, confirmations)
• Context-aware suggestions based on inbox state

📚 Ready-to-Use Resources:

• 6 detailed documents (3,500+ lines)
• Copy-paste workflow templates
• Comprehensive search pattern reference
• Common scenarios and solutions

Installing the Skill

The skill works alongside the MCP. Install it to your Claude Code user scope:

# Clone this repo (if you haven't already)
git clone https://github.com/patrickfreyer/apple-mail-mcp.git
cd apple-mail-mcp

# Install skill to user scope (available in all projects)
cp -r skill-email-management ~/.claude/skills/email-management

That's it! The skill activates automatically when you mention email management topics.

Using the Skill

Once installed, just ask Claude Code about email management:

Examples:

• "Help me achieve inbox zero"
• "Triage my inbox"
• "How should I organize my project emails?"
• "Find all emails from John about the Alpha project"
• "Clean up old emails from last year"

Claude will now:

1. ✅ Recognize email management requests
2. ✅ Load expert workflows and best practices
3. ✅ Use MCP tools intelligently
4. ✅ Provide actionable step-by-step guidance

Installation

Prerequisites

• macOS with Apple Mail configured
• Python 3.7 or higher
• At least one Mail account configured in Apple Mail
• Claude Desktop (for MCP Bundle installation) or any MCP-compatible client

Option 1: MCP Bundle (.mcpb) - Recommended

The easiest way to install is using the pre-built MCP Bundle:

1. Download the latest .mcpb file from the Releases page

2. Install in Claude Desktop:

   • Open Claude Desktop settings
   • Navigate to Developer > MCP Servers
   • Click Install from file
   • Select the downloaded .mcpb file
   • Restart Claude Desktop

3. Grant permissions when prompted:

   • Mail.app Control
   • Mail Data Access

Option 2: Manual Installation

1. Clone the repository:

git clone https://github.com/patrickfreyer/apple-mail-mcp.git
cd apple-mail-mcp

2. Create and activate a virtual environment:

python3 -m venv venv
source venv/bin/activate

3. Install dependencies:

pip install -r requirements.txt

4. Configure Claude Desktop by adding to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "apple-mail": {
      "command": "/path/to/apple-mail-mcp/venv/bin/python3",
      "args": [
        "/path/to/apple-mail-mcp/apple_mail_mcp.py"
      ]
    }
  }
}

5. Restart Claude Desktop

Building Your Own .mcpb Bundle

To build a distributable MCP Bundle:

cd apple-mail-mcpb
./build-mcpb.sh

The script will create apple-mail-mcp-v{version}.mcpb in the parent directory.

Usage Examples

Once installed, you can interact with Apple Mail using natural language in Claude:

Show me an overview of my inbox
How many unread emails do I have?

Search for emails about "invoice" across all folders in my work account
Show me the conversation thread about "meeting"

Organizing Emails

Move emails with "invoice" in the subject to my Archive folder
Mark all emails from [email protected] as read
Flag important emails about "deadline"
Delete emails from [email protected]

Composing & Responding

Configuration

Email Preferences (Optional)

You can configure personal email preferences that will be provided to the AI assistant when using email tools. This helps Claude understand your preferred email accounts, defaults, and workflow.

MCP Bundle Installation (.mcpb):

When installing via the .mcpb bundle, you can set preferences through Claude Desktop:

1. Open Claude Desktop settings
2. Navigate to Developer > MCP Servers
3. Click on the Apple Mail MCP server
4. Configure Email Preferences field

Example preferences:

Default to BCG account, show max 50 emails, prefer Archive and Projects folders

Manual Installation:

Add the env section to your claude_desktop_config.json:

{
  "mcpServers": {
    "apple-mail": {
      "command": "/path/to/venv/bin/python3",
      "args": ["/path/to/apple_mail_mcp.py"],
      "env": {
        "USER_EMAIL_PREFERENCES": "Default to BCG account, show max 50 emails, prefer Archive and Projects folders"
      }
    }
  }
}

What to include in preferences:

• Default email account name (e.g., "BCG", "Gmail", "Personal")
• Preferred maximum email results
• Frequently used mailboxes/folders
• Any workflow preferences

These preferences are automatically injected into every tool's description, helping Claude make better decisions aligned with your workflow.

Safety Limits

Several operations include safety limits to prevent accidental bulk actions:

• update_email_status: Default max 10 updates
• manage_trash: Default max 5 deletions
• move_email: Default max 1 move

These limits can be adjusted via function parameters when needed.

Permissions

On first use, macOS will prompt for permissions:

1. Mail.app Control: Required to automate Mail operations
2. Mail Data Access: Required to read email content

Grant both permissions in System Settings > Privacy & Security > Automation for full functionality.

Technical Details

• Framework: FastMCP - Python MCP server framework
• Automation: AppleScript for Mail.app interaction
• Platform: macOS only (requires Apple Mail)
• Python: 3.7+

Troubleshooting

Mail.app Not Responding

• Ensure Mail.app is running
• Check that permissions are granted in System Settings
• Restart Mail.app and Claude Desktop

Slow Performance

• Fetching email content is slower than metadata
• Use include_content: false when content preview isn't needed
• Reduce max_results for large searches

Mailbox Not Found

• Use exact folder names as they appear in Mail.app
• For nested folders, use "/" separator: "Projects/Amplify Impact"
• Some accounts (Exchange) may use different mailbox names

Permission Errors

# Grant permissions via System Settings
System Settings > Privacy & Security > Automation > [Your Terminal/Claude]
