How AI is Gaining Easy Access to Unsecured Servers through the Model Context Protocol Ecosystem

 

Artificial intelligence is becoming more powerful and versatile but connecting AI models with external tools and data is a challenge. Traditionally, developers had to build custom connectors for every integration, a time-consuming process that is fragile and hard to scale. The Model Context Protocol (MCP) changes that.

Whereas, developers would have to build custom connectors for every integration, a time-consuming process that is fragile and hard to scale, MCP acts as a universal interface, allowing large language models (LLMs) to connect with APIs, databases, and other resources through a standardized framework. Often likened to USB-C ports, MCPs act as single connectors that make AI integration simpler and more consistent. 

However, cybersecurity companies are now warning developers about the security posture of this rapidly growing MPC ecosystem—revealing that roughly 1,000 MCP servers are currently exposed on the public internet with no authorization controls in place. These unsecured servers represent a major vulnerability, giving attackers and potentially rogue AI agents an easy way to access sensitive systems.

How MCP Works

MCP is designed to streamline AI workflows. Instead of writing custom code for every tool, developers can use MCP to connect AI models to multiple resources quickly. Companies like Google have even launched managed MCP servers to make integration simpler.

The simplicity of the process is driving rapid adoption, but it’s also creating new security concerns. Unprotected MCP servers can serve as open doors to critical systems, exposing them to unauthorized exploitation. MCP’s strength lies in its ability to grant AI direct access to operational environments. But without proper safeguards, that same strength can be used to steal data, manipulate processes, or launch broader cyberattacks.

A Risky Rush to Adoption

A report by Bitsight Technologies Inc. highlights that MCP adoption is outpacing security practices. Developers eager to experiment often deploy MCP servers without implementing basic protections like authentication or encryption. This creates an attack surface that is both large and easy to exploit, and the consequences of successful attacks can be significant.

For example, an unsecured MCP server connected to a financial database could allow unauthorized access to confidential transactions. Similarly, an MCP linked to industrial control systems could allow an attacker to remotely and discretely alter settings that could cause real-world damage.

Given these risks, experts warn that if AI is given a universal key through MCP, the locks must be strong.

“MCP is still such a new technology, and everyone’s in a rush to test it, play with it, and roll it out across their organization. But that rush to get something working in production can have disastrous consequences.” – João Cruz, Principal Security Research Scientist, Bitsight, 2025

Mitigating MCP Security Risks

Organizations using MCP should treat security as a core requirement to its use, not an afterthought. Every MCP endpoint should require strong authentication to prevent unauthorized access. Data flowing through MCP should be encrypted both in transit and at rest to protect against interception, and continuous monitoring and auditing of MCP activity can help detect suspicious behavior before it escalates. Finally, permissions should be tightly controlled, so AI agents only access the resources they truly need.

Beyond technical measures, there is an urgent need for clear policy frameworks and legal considerations, which require skilled professionals who understand both AI integration and cybersecurity. More than simply a convenience for developers, MCPs are a powerful gateway that can impact entire enterprises if left unsecured. Organizations must invest in governance and training to ensure this technology is deployed responsibly.
