MS-365 MCP Server is an MCP server that provides an interface between Model Context Protocol clients and Microsoft 365 services such as email and calendar systems. It is packaged as a containerized service, incorporating OAuth authentication workflows to handle permissions securely alongside OpenTelemetry instrumentation for monitoring and observability. Enterprise teams, system administrators, and developers use this server to allow AI assistants to interact with productivity data while maintaining visibility into server metrics and request traces. By bridging large language models and Microsoft 365, it enables automated querying of messages, management of schedules, and integration with broader enterprise workflows. The implementation runs inside container environments, making it suitable for deployment in structured cloud architectures where auditing, token management, and centralized log tracking are mandatory operational requirements.
Navigate to the official GitHub repository at https://github.com/nickels/office365-mcp-server to review the setup instructions and prerequisite configuration options. 2. Configure your Microsoft 365 OAuth application credentials and OpenTelemetry settings according to the repository documentation. 3. Build and run the containerized MCP server using your container runtime. 4. Register the running container server within your MCP client configuration file (such as Claude Desktop or Cursor) using the repository instructions for stdio or remote connection endpoints. 5. Restart your MCP client to verify the connection.
