The rapid rise of AI has brought incredible capabilities, from email drafting to data analysis, but one challenge remains: connecting these AI assistants with the myriad apps and data sources that businesses rely on. Enter the Model Context Protocol (MCP), an emerging open standard that some have dubbed"USB-C for AI integrations."

‍

In this updated analysis, we will explore what the MCP is, why it is important to business leaders, and how it has evolved through 2025. We will examine which technology giants have come together in support of this standard, the concrete benefits it offers, the security challenges that have emerged, and a balanced view of its limitations and future prospects.

‍

What is the MCP and why is it important?

MCP is essentially a universal communication language that enables AI systems to communicate with external tools, databases, and services in a consistent manner. Instead of creating a custom integration for each app or data silo, developers (and by extension companies) can use MCP as a single standardized bridge.

‍

Think of it as connecting your AI to any software system as easily as connecting a device to a USB port. By eliminating fragmented, one-time connectors, MCP makes it "easier and more reliable" for AI assistants to access the data they need from various sources.

This is important because even the most intelligent AI is only as useful as the information it can work with. Traditionally, linking an AI model to one's cloud drive or HR database involved considerable effort and maintenance on the part of IT.

‍

Each new data source spoke its own "technology language" and required custom code, which was difficult to scale.

‍

MCP solves this problem by providing a common protocol so that an AI assistant can tap into real-time business data or trigger actions in software through a defined and secure interface. As Anthropic said, "The result is a simpler and more reliable way for AI systems to access the data they need."

‍

In short, MCP frees AI from isolation and helps it become a truly integrated part of business workflows.

‍

Evolution and adoption in 2025

Since it was introduced in late 2024, MCP has gained considerable momentum. What was initially primarily an Anthropic initiative has turned into a widely adopted industry standard. Here is how the adoption of MCP has evolved:

Almost universal support from AI leaders

The adoption of MCP reached a critical point when major industry players began to support it:

• OpenAI: In March 2025, OpenAI announced the adoption of MCP for all its products, integrating it into its Agent SDK and adding support for the ChatGPT desktop app and the Responses API. OpenAI CEO Sam Altman noted that "people love MCP" and confirmed the integration with OpenAI's agent toolkit.
• Google: In April 2025, Google DeepMind announced that they too would be adding MCP support to their Gemini and SDK models. Google DeepMind CEO Demis Hassabis described MCP as "a good protocol that is rapidly becoming an open standard for the agentic era of AI."
• Microsoft: Microsoft has integrated MCP into its Azure AI services and contributed new tools to the MCP ecosystem. In early 2025, Microsoft announced that its Azure OpenAI "Copilot" Studio would allow users to connect AI agents to MCP servers directly. Microsoft even launched an MCP-based Playwright server that allows AI agents to control a Web browser for tasks such as clicking on sites and collecting data.
• Amazon: Amazon has reportedly added MCP support in its Amazon Bedrock AI platform, signaling interest from the cloud services arena as well.

Ecosystem growth

The MCP ecosystem has grown exponentially:

• Wide adoption by developers: By February 2025, more than 1,000 community-created MCP servers were available, as highlighted in the Hugging Face Turing Post blog.
• Integration into the Java ecosystem: MCP has spread into the enterprise Java ecosystem, with frameworks such as Quarkus and Spring AI now supporting MCP server deployments. Tools such as JBang make it easier for Java developers to run MCP servers.
• IDE support and development tools: Popular code editors and IDEs have adopted support for the protocol, including tools such as Cursor, Cline, and Goose.
• C# SDK: A C# SDK was developed for MCP, further expanding its accessibility for Microsoft developers.

Broad industry support (Anthropic, OpenAI, Google, Microsoft, Amazon, and a growing community) suggests that MCP is truly becoming a universal standard for AI connectivity. One analyst described this convergence as the dawn of an "AI protocol era," in which interoperability standards like MCP unlock a new level of AI capability.

Simplifying administrative activities: real use cases

One of the most significant impacts of the MCP is its ability to automate routine administrative tasks across multiple business systems. Because the MCP allows AI agents to retrieve information or perform updates in other applications, an AI assistant can perform complex workflows involving multiple applications without requiring human intervention or custom code.

Sales flow automation and scheduling

An IA sales assistant, using the MCP, can independently manage many steps in the sales process:

• Collect details of new potential customers from web forms
• Searching for potential customer history in CRM
• Draft and send personalized contact emails
• Automatically schedule meetings and update CRM

As described in a case study by Teammates.ai: "This seamless process reduces manual data entry and allows the sales team to focus on closing deals rather than administrative tasks."

Creating reports and updating data

With MCP, an AI assistant can:

• Extract real-time data from databases or ERP systems
• Compile weekly reports
• Publish reports to shared drives or send them via email

MCP connectors for database systems such as PostgreSQL facilitate these business intelligence and reporting use cases. AI can query the database through the MCP interface to get the latest data and generate insights, ensuring that reports are always up-to-date.

Integration with CRM and communication tools

For CRM updates, an IA agent can use an MCP connector to automatically update customer records after analyzing emails or support tickets. Leading CRM and communication tools are integrating this model:

• MCP adapters for Slack to automate channel reminders and updates
• MCP "Time" server to manage time zones and calendars
• Integrations with systems such as HubSpot to manage contacts and companies

Companies are already experiencing concrete benefits. For example, Block (Square's parent company) has used the MCP to build "agent" systems that handle mechanical tasks so that people "can focus on creative work."

‍

Key benefits for companies

If the MCP continues on its current trajectory, it offers several concrete benefits to companies that adopt AI in their operations:

Time saving and efficiency

By automating repetitive tasks between systems, MCP-based AI agents free employees from administrative work. Routine updates, data entry or copy-paste between platforms can occur instantly in the background. Companies report significant efficiency gains when AI assistants manage entire workflows, allowing staff to focus on strategy and higher-value-added activities.

‍

In practical terms, this could mean:

• Sales representatives spending more time with customers and less time in CRM administration
• Analysts spending less time collecting data and more time interpreting it

Reduced errors and increased accuracy

Human error in manual processes (such as mistyping a number in a report or forgetting to update a record) can cost time and money. An AI built into MCP extracts data directly from source systems and updates records consistently, minimizing these errors. In addition, because the AI can access up-to-date information in real time, its responses and results are based on the latest facts, leading to more accurate insights.

‍

Improved decision making

With richer context and up-to-date data at AI's fingertips, business leaders gain better support for decision making. For example, an AI assistant could quickly tap into sales data, inventory levels or market news during a planning meeting, providing immediate analysis.

‍

MCP essentially extends an AI model's knowledge beyond its training data, which "significantly improves [AI's] functionality" in practical business scenarios. The result is AI-generated reports, recommendations or responses that are more relevant to the actual business situation.

Faster integration and flexibility

Adopting new software or changing platforms becomes easier when both systems and AI tools speak MCP. Instead of commissioning custom integrations for each new system, an MCP connector can be sought (or quickly developed). This standardization means plug-and-play compatibility, similar to how any USB-C accessory works with a laptop.

It also future-proofs investments: you can "easily replace or add tools without costly rebuilds" of AI integrations. In other words, MCP can help keep the technology stack agile and avoid being tied to the closed ecosystem of a single vendor.

Collaborative innovation

Because MCP is open source and enjoys broad support, it benefits from community-driven innovation. There are already dozens of predefined MCP servers (connectors) for services ranging from Google Drive to Slack to databases. This shared pool of integrations means that companies can leverage community input and best practices instead of reinventing the wheel.

‍

It also encourages software vendors to provide MCP compatibility as a feature, knowing that it can expand their reach. Over time, this open ecosystem can reduce the cost of AI adoption as more "off-the-shelf" MCP integrations become available.

‍

Security challenges emerged in 2025

Despite its many benefits, 2025 has seen major security concerns emerge related to the MCP. Researchers and security professionals have identified several potential vulnerabilities:

Risks of prompt injection

Simon Willison pointed out problems with "prompt injection" in MCP servers. Because MCP allows language models to invoke tools based on user input, malicious messages could contain hidden instructions that the model executes without explicit user permission.

For example, an attacker might send a message that looks harmless but contains hidden instructions that lead the AI to send data to unauthorized recipients or perform malicious actions through connected MCP tools.

"Rug Pull" issues and silent modifications.

An attack called "Rug Pull: Silent Redefinition" has been identified in which MCP tools can change their definitions after installation. A user could approve a seemingly secure tool, which could later silently change its behavior to redirect API keys to an attacker.

Server collision and conflict issues

With multiple servers connected to the same agent, a malicious server could overwrite or intercept calls made to a trusted server. This creates "confused deputy" vulnerabilities, where an attacker can actually induce tools to do what he wants by manipulating input.

Problems with authentication and credential management

Security researchers have identified risks related to the exposure of plain text credentials and the lack of strong authentication mechanisms in MCP deployments. A Palo Alto Networks report explains that MCP configurations could store authentication tokens that, if compromised, would allow an attacker to impersonate the legitimate MCP server.

Formal security research

The severity of these security problems is such that several formal academic studies have emerged in 2025:

• A paper in arXiv titled "Model Context Protocol (MCP): Landscape, Security Threats, and Future Research Directions" systematically analyzed the security and privacy risks associated with the MCP server lifecycle.
• Another study, "Enterprise-Grade Security for the Model Context Protocol (MCP): Frameworks and Mitigation Strategies," proposed a comprehensive framework for risk mitigation in enterprise implementations of MCP.

Experimental nature and risks of early adoption

Despite the enthusiasm and rapid development, it is critical to recognize that MCP remains an experimental technology. As one Gartner analyst pointed out, "authentication/authorization for MCP is limited," suggesting that the protocol is not yet fully mature for critical enterprise implementations. Another expert from TheCube Research commented that "MCP is still in many ways a science project and much needs to be done to make it work," highlighting its still-evolving nature.

‍

Companies that adopt MCP in the early stages may face several significant disadvantages:

Instability and changes in specifications

Like any emerging standard, MCP is still evolving rapidly. Specifications could change substantially, making current implementations obsolete and requiring costly revisions. Future roadmaps include key elements such as service discovery and support for stateless operations needed for serverless computing environments, indicating that the protocol is not yet complete.

Lack of established expertise and best practices

The talent pool with hands-on experience in MCP implementation is still limited. Companies may find themselves paying a premium for MCP skills or investing heavily in in-house training to build this capability. In addition, best practices for secure MCP implementation are still being defined, with researchers continuing to identify new vulnerabilities.

Hidden costs of maintaining and updating

Early adopters will face higher maintenance costs as the protocol matures. Any significant updates to the MCP specification may require revisions to existing implementations, representing an ongoing commitment of resources.

Initial fragmentation of the ecosystem

Although the major players have declared support for MCP, there are indications that each might implement it in slightly different ways. As one analyst notes, "by early 2025 each [OpenAI and Microsoft] had their own tools for MCP." This fragmentation could undermine one of the key benefits of MCP: universal interoperability.

Reputational risks from security incidents

With new security vulnerabilities continuing to emerge, early MCP deployments may be particularly vulnerable. A significant security incident could not only damage corporate data but also erode customer trust, especially if it involves unauthorized access to sensitive information by compromised AI agents.

‍

Other limitations and considerations

In addition to the risks of early adoption and security concerns, business leaders should consider additional limitations:

Incomplete adoption in the market

Despite strong momentum, the MCP is not yet a universally adopted standard among all technology vendors. As one industry expert noted in March 2025, MCP is the "best option [currently] for bridging the gap" between AI and data sources, "but it has not yet become a de facto standard." This means that in the short term you may still encounter major tools that do not offer MCP integration.

Learning curve and implementation effort

Adopting MCP is not as simple as flipping a switch; there is a technical component. The IT team or software vendors will need to set up MCP "servers" for each data source or service to be connected (unless one already exists) and make sure they are maintained.

‍

In essence, data providers or tool owners must structure interfaces according to MCP specifications. This shifts some of the integration work to those vendors, which is great when done (since all AI clients can then use it easily) but could be a hindrance if vendors are slow to offer MCP support.

‍

Smaller organizations might rely on third-party solutions or wait for their software vendors to include MCP connectors in upgrades. The good news is that many SDKs and open source tools are available to facilitate this process, but some technical investment and experience is still required to get started.

Governance and formal standardization

MCP was promoted by Anthropic, not by a neutral standards body. Although it is open source (MIT-licensed) and community-driven, some skeptics point out that Anthropic remains a key factor in its direction.

‍

In theory, there is a risk (however small) that competing "standards" could emerge or that MCP could bifurcate if the major players disagree on its evolution. One commentary warned that without broad collaboration, MCP "could unintentionally accelerate artificial intelligence protocol wars, leading to competing standards and closed ecosystems."

‍

So far, the trend is the opposite: rivals are coalescing around MCPs rather than inventing their own. But companies should remain vigilant about developments in the industry.

The limitations of AI persist

Finally, remember that the MCP is a facilitator; it makes it easier for the AI to act on your data, but it does not magically solve all AI challenges. An AI agent could retrieve information from your database flawlessly, but it could still misinterpret that information or apply it incorrectly if the underlying model logic is faulty.

‍

You will still need good governance of AI decisions and supervision to ensure quality results. Think of the MCP as a tool that gives your AI better tools; you still need to train and direct the "worker" who uses those tools.

‍

Perspectives on adoption and what's next for business leaders

By mid-2025, the MCP is in the midst of accelerating from an innovative concept to an established industry standard. With all the major AI players actively implementing it, the protocol has achieved a sharp rise in credibility in a short time.

The current state of adoption can be summarized as follows:

• MCP is available and usable today (in open source form)
• It is integrated into major artificial intelligence platforms (Anthropic's Claude, ChatGPT, Microsoft and Google's AI services)
• There is a growing ecosystem of connectors and tools
• Real-world use cases have demonstrated its value in automating workflows
• Important safety issues have emerged that require attention

What should business decision makers pay attention to in the future?

Improvements to security and governance

The MCP authorization specification is relatively new and still leaves open questions about secure server implementation. As the protocol sees wider adoption, we can expect the authorization component to mature and develop along with it.

A more formal governance consortium for MCP, potentially involving multiple vendors, is likely to be formed to ensure that the standard evolves safely and in the best interest of all stakeholders.

‍

Enterprise-grade solutions

In the coming months, more refined MCP-based services and platforms can be expected to appear. Managed solutions may emerge in which you will not have to create any connectors yourself, but will be able to choose from a menu of MCP integrations in a marketplace.

This will make it even easier for companies without large development teams to adopt the technology. Business leaders should ask their software vendors about the MCP roadmap and encourage it if improving interoperability is a priority.

‍

Defining security best practices

As MCP-related projects grow, so will knowledge about how to implement them securely. Researchers have already begun to formalize MCP-specific security frameworks. Companies should:

• Do not download or connect AI to untrusted MCP or OpenAPI servers
• Inspect code, interface definition, check for backdoors and hidden instructions
• Preferably, use servers from trusted entities
• Implement robust authentication and authorization controls
• Keeping the human being in the decision-making process (Human-in-the-Loop)
• Conduct code reviews, static analysis, and threat modeling

Realistic pilot projects

Rather than a radical approach, it is advisable to identify some high-value but low-risk administrative workflows in your company that could benefit from AI automation. For example:

• An AI-based meeting planning assistant that uses MCP to check calendars and book rooms
• An internal AI-based helpdesk that can search a knowledge base for frequently asked questions and create ticket updates

Implementing a pilot project with clear success criteria will help to understand firsthand the impact and limitations of MCP. It will also bring to light any organizational problems (such as data silos or access permissions) that need to be resolved before wider implementation.

‍

Conclusion: A balanced approach

The Model Context Protocol represents an important step toward AI that is truly useful in the business environment, not only intelligent in theory but also concretely functional in our everyday software environment. By standardizing the way AI systems interact with the tools and data we use, the MCP has the potential to save us time, reduce errors, and gain more value from both our investments in AI and our existing software.

‍

However, it is critical to maintain a balanced approach. As one analyst wisely noted, "MCP's promise is huge, but its long-term success depends on community adoption, clarity of documentation, and demonstrated real-world benefits." It is advisable to experiment and get involved, but avoid tying critical processes only to MCP until it is more mature.

‍

For most organizations, a phased approach is probably the most prudent:

1. Learning phase: Devote limited resources to experimenting with MCP in non-production environments to become familiar with its capabilities and limitations.
2. Non-critical pilot projects: Implement MCPs in non-critical areas of the organization where risk is manageable and potential efficiency gains are high.
3. Ongoing evaluation: Closely monitor the evolution of the MCP ecosystem, including security issues, improvements in specifications, and adoption patterns by other companies.
4. Phased expansion: Only when the first pilot projects demonstrate clear value and safety issues are adequately addressed, consider wider adoption.

For business leaders, now is the time to pay attention to this emerging trend, but with a healthy dose of skepticism. While the MCP may one day become as ubiquitous as USB or Wi-Fi standards have been, it is still in a relatively experimental stage.

‍

Companies that can afford to be ahead of the curve can gain competitive advantages by exploring MCP applications in administrative and operational workflows. Others would do well to observe carefully, learn from others' experiences, and adopt MCP only when the benefits clearly outweigh the risks.

‍

The "universal connector" for AI is emerging; however, wisdom suggests proceeding with cautious curiosity rather than hasty adoption.
