MCP Outlook Tools

MCP Outlook Tools is an MCP server that enables AI assistants like Claude Desktop to connect with a locally installed Microsoft Outlook client on Windows. It is designed for knowledge workers and professionals who want to automate calendar scheduling and email workflows directly from conversational AI interfaces. By using the Windows COM interface via pywin32, the server allows language models to read appointments across specified date ranges, insert new calendar events with custom busy statuses and categories, and draft or send emails to single or multiple recipients. The server also provides capabilities to search Outlook email archives by keyword and date, accommodating Japanese text encoding. Because it operates through local Outlook COM automation, MCP Outlook Tools relies on the existing local Outlook profile and authentication without storing credentials in code. Users retain safety control through confirmation prompts before emails are sent, making it practical for day-to-day office coordination.
