The Hidden Risks of MCP

Most IT and engineering leaders don't realize how easily MCP implementations can expose API keys, leak sensitive data, and compromise security. Here's what you need to know.

What most leaders don't realize

Critical Security Vulnerabilities

API Keys Exposed in Plain Text

MCP servers that don't require OAuth send API keys as plain bearer tokens. These keys are transmitted unencrypted and sent directly to the LLM, making them easily interceptable.

Real Risk: API keys can be logged, cached, or accessed by anyone with network visibility.

Rogue MCPs Accessing Proprietary Data

Untrusted MCPs from unknown developers can be installed by users, giving them access to company databases, codebases, and sensitive information without IT oversight.

Real Risk: Data exfiltration, industrial espionage, and compliance violations.

Zero Visibility & Control

No way to monitor what data is being accessed, by whom, or how often. No audit trails for compliance, no ability to revoke access, no rate limiting.

Real Risk: Compliance failures, uncontrolled costs, and security blind spots.

How to Secure Your Agent Stack

1

Audit Current MCPs

Identify all MCP servers currently in use across your organization

2

Implement Gateway

4

Monitor & Govern

Ongoing monitoring, alerting, and policy enforcement

Is your organization at risk?

Quick risk assessment

Do you know all the MCP servers installed across your organization?
Can you see what data each AI agent is accessing?
Are your API keys protected from exposure to third-party MCPs?
Do you have audit trails for all AI agent data interactions?
Can you instantly revoke access if an MCP is compromised?
Do you monitor for unauthorized data access or unusual patterns?

If you answered "no" to any of these questions:

Don't Wait Until It's Too Late

Secure your agent stack before a security incident occurs. Join enterprises that proactively govern their AI data access.
