What are the risks of using the Google Mail MCP without an AI gateway?
- Uncontrolled reads — AI agents can pull data out of Google Mail with no visibility into what was accessed.
- Ungoverned writes — Agents can create or modify records in Google Mail with no approval step.
- Destructive actions — Agents can delete or overwrite Google Mail 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. Google Mail is an MCP server that exposes a defined set of tools an AI agent can call.
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.
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.
