Teams MCP - Technical Manual

1 min read

Overview

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

Note: The Teams MCP Server exposes 8 MCP tools that AI clients invoke on demand to read, search, and send Teams chat and channel messages. Every call is served live from the Microsoft Graph API — nothing is copied into the Unique knowledge base.

Deployments that additionally enable transcript capture (UNIQUE_INTEGRATION=enabled) register four more tools and run an asynchronous ingestion pipeline. That capability is documented in the Recordings & Transcripts - Technical Manual.
