License: MIT

✨ Features

• 🔍 Natural Language Email Search - Search your inbox using plain English
• 📧 Executive Style Profiles - Drafts match recipient's communication style
• 🎯 Context-Aware Responses - Uses full email threads for context
• 📤 One-Click Publishing - Create drafts directly in Outlook
• 🚀 One-Time Setup - Configure once, use in any Claude Code conversation

🎭 Executive Profiles

The plugin automatically matches recipients to communication styles:

• Charles Lamanna - Conversational-professional, strategic, engaging
• Nirav Shah - Action-oriented, decisive, technical, timeline-focused
• Robert Bruckner - Direct, data-driven, strategic, analytical
• James Oleinik - Collaborative, balanced, team-focused, thoughtful

Unknown recipients use a professional default style.

🚀 Quick Start

Prerequisites

• Python 3.8+
• Claude Code CLI installed
• Agent 365 account with email access
• Microsoft 365 mailbox

Installation (2 commands!)

1. Clone and install

   git clone https://github.com/jamesol-msft/claude-email-draft-plugin.git
   cd claude-email-draft-plugin
   pip install -r requirements.txt
   python setup.py
   

2. Restart Claude Desktop/CLI

That's it! The setup script automatically:

• ✅ Installs MCP proxy to your home directory
• ✅ Installs skill to ~/.claude/skills/email-draft/
• ✅ Configures Claude Desktop MCP server
• ✅ Provides token setup instructions

Token Setup (Optional - for real email access)

For testing without a real token, the plugin works in mock mode by default. For real email access:

# If you have get_agent365_token.py
python get_agent365_token.py

# Or create a mock token for testing
mkdir -p ~/.agent365
cat > ~/.agent365/auth-token.json << 'EOF'
{
  "access_token": "mock_token_for_testing",
  "token_type": "Bearer",
  "expires_in": 3600,
  "expires_at": 9999999999
}
EOF

Verify Setup

python verify_setup.py

This checks that everything is configured correctly.

🏗️ Architecture

Claude Code
    ↓ (MCP protocol - JSON-RPC 2.0 over stdio)
agent365_mcp_proxy.py
    ↓ (HTTPS)
Agent 365 Mail Server
    ↓ (Microsoft Graph API)
Microsoft 365 (Outlook)

Key Components:

• MCP Proxy (~550 lines Python) - Lightweight bridge between Claude Code and Agent 365
• Skill File (~830 lines Markdown) - Executive profiles and workflow logic
• Configuration - Simple JSON config for Claude Desktop

🔧 MCP Tools

The proxy exposes 3 tools to Claude Code:

Tool	Purpose	Typical Latency
search_messages	Search emails with natural language	30-90s
get_message	Retrieve full email details by ID	1-3s
create_draft	Create draft in Outlook	1-3s

🔒 Security

• Tokens stored locally (~/.agent365/auth-token.json)
• Tokens expire after 1 hour (manual refresh required)
• No credentials in config files
• All communication over HTTPS
• MCP proxy runs locally (no external services)

🐛 Troubleshooting

Token expired (401 error)

# Refresh your Agent 365 token
python get_agent365_token.py

Proxy not starting

• Check Python version: python --version (need 3.8+)
• Check file path in claude_desktop_config.json
• Check Claude Code logs: View → Developer → Toggle Developer Tools

Skill not appearing

• Verify file location: ~/.claude/skills/email-draft/SKILL.md
• Restart Claude Code
• Check for syntax errors in SKILL.md

See TROUBLESHOOTING.md for more solutions.
