# Teams MCP - Technical Manual

## Overview

This section contains detailed technical documentation for developers and architects working with the Teams MCP Server.

**Note:** The Teams MCP Server is both an MCP server and a connector — it exposes **12 MCP tools** (8 chat/messaging + 4 transcript/KB) that AI clients invoke on demand, and once a user connects their account, it automatically ingests meeting transcripts into the Unique knowledge base in the background. This contrasts with pure connector-style servers which ingest data silently without exposing tools.

**Key distinction:** meeting **transcripts and recordings are ingested into Unique** (copied into the knowledge base) and queried from that stored copy; Teams **chat and channel messages are accessible in Unique through the MCP tools but are never ingested** — they are fetched live from the Microsoft Graph API and exist only in Microsoft. "Not ingested" is about storage, not accessibility. See [README — Where the Data Lives](https://docs.unique.ai/it-operators/integrations-connectors/teams-mcp).
