EWS Meeting MCP

The MCP server for safely scheduling Outlook meetings on on-prem Exchange EWS.

EWS Meeting MCP is built for organizations that still run Microsoft Exchange on-premises and cannot expose calendar workflows through cloud-first Microsoft Graph integrations. It keeps credentials local, supports strict enterprise security environments, and requires preview-confirmed writes before creating, updating, or cancelling meetings.

Highlights

• Resolve attendees and Exchange room mailboxes.
• Suggest available meeting slots before booking.
• Preview meeting changes before any write operation.
• Create, update, and cancel Outlook meetings through Exchange EWS.
• Keep Exchange credentials local with environment variables or macOS Keychain.
• Maintain audit-friendly lifecycle records for scheduling actions.
