You cannot govern what you cannot name, and most enterprises cannot name every MCP server already connected to their systems.
MCP is how AI agents stop advising and start acting. It is also how a single prompt reaches your Git repositories, your ticketing system, and your production database. Every server an employee connects on their own machine, with their own token, is a new path into your estate that your security team never approved and cannot see.
This is not a hypothetical risk. It is the default shape of MCP adoption today: one developer wiring one tool to one model, repeated across thousands of employees with no central point of control. Security teams describe it as death by a thousand cuts. No single connection looks alarming. The aggregate is impossible to defend.
This field guide sets out eight principles for closing that gap, and shows how the Airia MCP Gateway implements each one.
Key Takeaways:
- A gateway is an architecture decision, not a policy setting. Until every tool call traverses one managed path, every other control in this guide is optional from the attacker’s point of view.
- Credential sprawl is the failure mode that kills MCP programmes. A personal access token pasted into a laptop config file is invisible to your identity team and survives long after the employee who created it is gone.
- A tool description is not documentation. It is untrusted input the model treats as trusted. A malicious server can plant instructions inside a description, a name, or a field, and the model cannot tell that text apart from a legitimate command.
- Context windows put a hard ceiling on how many integrations an agent can hold at once. Enterprises with hundreds of systems need agents that search for capabilities on demand, not agents that load an entire catalogue upfront.
- The integrations with the most business value are usually the ones no vendor has packaged. Internal APIs and proprietary systems need a path into governance that does not require building and operating a bespoke server for every endpoint.
