Microsoft Outlook MCP Server for Claude & Antigravity (AGY)

A high-performance Model Context Protocol (MCP) server providing direct, secure access to your Microsoft 365 Outlook emails, calendar, and contacts from:

• Claude Code CLI
• Claude Desktop
• Antigravity CLI (AGY)

🔒 Privacy & Security Architecture

• Human-in-the-Loop by Design: All outbound message drafting defaults to your Outlook Drafts folder for manual review. Direct unreviewed sends (outlook_send_mail) require an explicit confirm_send=True flag to prevent accidental dispatches.
• Indirect Prompt Injection Defense: Incoming email bodies are encapsulated in <untrusted_email_body_content> XML tags to ensure AI models parse external content strictly as passive data.
• Zero Cloud Tokens / No Passwords: Connects 100% locally to your running Windows Outlook Desktop application via Windows MAPI (win32com).
• Strict .gitignore: All local configs, caches, and environments are ignored.
