What are the risks of using the Microsoft Teams MCP without an AI gateway?
- Uncontrolled reads — AI agents can pull data out of Microsoft Teams with no visibility into what was accessed.
- Ungoverned writes — agents can create or modify records in Microsoft Teams with no approval step.
- Destructive actions — agents can delete or overwrite Microsoft Teams data with no approval gate or audit trail.

Frequently asked questions
What is MCP?
MCP (Model Context Protocol) is the open standard that lets AI models and agents connect to external tools and data sources through a common interface, instead of a custom integration for every tool. Microsoft Teams is an MCP server that exposes a defined set of tools an AI agent can call. Barndoor sits at that connection point, applying access policies and audit logging to every tool call regardless of which AI client is making it.
Is Barndoor secure?
Yes. Barndoor is SOC 2 Type II compliant. Barndoor enforces fine-grained access control, requires approval before destructive actions, protects sensitive data with data loss prevention, and logs every action for audit.
How are Microsoft Teams schema changes handled?
Barndoor tracks tool and schema changes on Microsoft Teams. New or changed tools inherit deny-by-default access until an admin reviews and approves them, keeping runtime enforcement current without manual reconfiguration. Every schema change is captured in the audit trail alongside who approved it.
Do users have to enter tokens manually?
No. Barndoor brokers the OAuth connection to Microsoft Teams centrally, so users and agents never handle or store a standing token themselves. Access is granted and revoked through policy instead of shared credentials.
Can I deploy custom-built MCP servers?
Yes. Barndoor supports customer-built MCPs, so internal tools and systems your team builds get the same policy enforcement and audit trail as Barndoor MCPs and official MCPs.
How can I get started with Microsoft Teams and Barndoor?
Connect Microsoft Teams once, define your access policies, and go live across every AI client your team uses. Setup takes three steps: connect the server, define policies by role or agent, and roll out to Claude, Cursor, ChatGPT, and any other MCP-compatible client.
