What are the risks of using the OneNote MCP without an AI gateway?

• Uncontrolled reads — AI agents can pull data out of OneNote with no visibility into what was accessed.
• Ungoverned writes — agents can create or modify records in OneNote with no approval step.
• Destructive actions — agents can delete or overwrite OneNote data with no approval gate or audit trail.

Why connect OneNote with the Barndoor AI gateway?

Barndoor MCP Governance is the gateway between your AI agents and the tools they use.

• Centralized MCP management — One place to manage and control every MCP server across the organization so your team has an approved catalog of MCP servers that employees and AI agents connect through.
• Universal connection — One universal URL works across every AI provider your team uses.
• Fine-grained access controls — Set access policies for how AI is connecting with OneNote based on human identities, agent profiles, tool-access, context, and data fields.
• Protect sensitive data — Keeps sensitive data from reaching a model or AI agent with PII detection, masking, tokenization, redaction, and more.
• Observability — Real-time reporting and dashboards that give you visibility into what AI is doing with OneNote, how policies are being enforced, and who (human or agent) is doing what.
• Enterprise-grade security — Stay compliant with audit trails and logging.

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. OneNote 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 can I get started with OneNote and Barndoor?
  Connect OneNote 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 compatible clients.
