Exposes Microsoft 365 services (Teams, SharePoint, OneDrive, Outlook, etc.) as MCP tools that Claude and other LLM clients can invoke through standardized tool-calling interfaces. Implements the Model Context Protocol specification to translate M365 REST API calls into LLM-compatible function schemas with automatic authentication handling via Microsoft Graph API credentials.

Manages OAuth 2.0 token lifecycle and Microsoft Graph API permission scopes at the tenant level, automatically handling token refresh, scope validation, and delegated vs. application permissions. Implements Azure AD authentication patterns to ensure that LLM-invoked M365 operations respect the authenticated user's permissions and organizational policies without exposing credentials to the LLM client.

Enables Claude and other LLMs to query Teams conversations using natural language or structured filters, returning message threads with metadata (sender, timestamp, channel context). Translates LLM search intents into Microsoft Graph API queries against the Teams service, handling pagination and result ranking to surface relevant conversations within token budgets.

Allows Claude and other LLMs to search SharePoint sites and document libraries using natural language, returning file metadata, content previews, and download URLs. Implements Microsoft Graph Sites API queries with support for filtering by site, library, document type, and metadata properties, enabling AI agents to locate and surface relevant documents without manual navigation.

Enables Claude and other LLMs to draft, format, and send emails on behalf of authenticated users through MCP tool calls. Implements email composition with support for recipients, subject, body formatting, attachments, and scheduling, translating LLM-generated email content into Microsoft Graph Mail API calls while respecting user permissions and organizational email policies.

Enables Claude and other LLMs to list, read, and retrieve files from OneDrive using MCP tool calls, supporting file metadata queries, content preview generation, and file download URLs. Implements Microsoft Graph Drive API operations with support for folder navigation, file filtering, and content extraction to provide LLMs with access to user files for analysis and context.

Enables Claude and other LLMs to create, read, and modify calendar events in Outlook using MCP tool calls. Implements calendar operations with support for event details (title, time, attendees, location), recurring patterns, and attendee management, translating LLM-generated scheduling requests into Microsoft Graph Calendar API calls while handling timezone conversion and conflict detection.

Implements the Model Context Protocol (MCP) server specification, exposing M365 capabilities as standardized LLM tools with JSON Schema definitions. Handles MCP request/response serialization, tool discovery, parameter validation, and error handling, enabling any MCP-compatible LLM client (Claude, custom agents) to invoke M365 operations through a unified interface without client-specific integration code.
