The relentless pursuit of ever-larger AI models has dominated headlines, but a quieter, more profound revolution is underway: standardization. The Model Context Protocol (MCP), introduced by Anthropic in November 2024, is poised to reshape the AI landscape by standardizing how AI applications interact with the world beyond their initial training data. Think of it as the HTTP and REST of the AI world, providing a universal language for AI models to connect with external tools and services.
While countless articles have dissected the technical aspects of MCP, its true power lies in its potential to become a ubiquitous standard. Standards are not merely organizational frameworks for technology; they are catalysts for exponential growth. Early adopters will ride the wave of innovation, while those who ignore it risk being left behind. This article explores the significance of MCP, the challenges it presents, and its transformative impact on the AI ecosystem.
From Chaos to Context: The MCP Revolution
Imagine Lily, a product manager at a bustling cloud infrastructure company. Her daily routine involves juggling a multitude of projects across various tools like Jira, Figma, GitHub, Slack, Gmail, and Confluence. Like many in today’s fast-paced work environment, she is constantly bombarded with information and updates.
By 2024, Lily recognized the remarkable capabilities of large language models (LLMs) in synthesizing information. She envisioned a solution: feeding data from all her team’s tools into a single model to automate updates, generate communications, and answer questions on demand. However, she quickly realized that each model had its own proprietary way of connecting to external services. Every integration pulled her deeper into a single vendor’s ecosystem, making it increasingly difficult to switch to a better LLM in the future. Integrating transcripts from Gong, for example, required building yet another custom connection.
Enter Anthropic’s MCP: an open protocol designed to standardize how context flows to LLMs. This initiative quickly gained traction, with support from industry giants like OpenAI, AWS, Azure, Microsoft Copilot Studio, and eventually, Google. Official Software Development Kits (SDKs) were released for popular programming languages such as Python, TypeScript, Java, C#, Rust, Kotlin, and Swift. Community-driven SDKs for Go and other languages soon followed, accelerating adoption.
Today, Lily leverages Claude, connected to her work applications through a local MCP server, to streamline her workflow. Status reports are generated automatically, and leadership updates are just a prompt away. When evaluating new models, she can seamlessly integrate them without disrupting her existing integrations. When she works on personal coding projects, she uses Cursor with a model from OpenAI, connected to the same MCP server she uses with Claude. Her IDE seamlessly understands the product she is building, thanks to the ease of integration provided by MCP.
The Power and Implications of Standardization
Lily’s experience highlights a fundamental truth: users prefer integrated tools, dislike vendor lock-in, and want to avoid rewriting integrations every time they switch models. MCP empowers users with the freedom to choose the best tools for the job.
However, standardization also brings implications that need to be considered.
Firstly, SaaS providers lacking robust public APIs are vulnerable to obsolescence. MCP tools rely on these APIs, and customers will increasingly demand support for AI applications. With MCP emerging as a de facto standard, SaaS providers can no longer afford to neglect their APIs. They must invest in well-documented and comprehensive APIs to ensure their services remain compatible and competitive within the evolving AI landscape. This includes providing clear and concise documentation, offering developer support, and actively monitoring API usage to identify areas for improvement. Failure to do so risks losing customers to providers that offer seamless integration with MCP-enabled AI tools.
Secondly, AI application development cycles are poised to accelerate dramatically. Developers no longer need to write custom code to test simple AI applications. Instead, they can integrate MCP servers with readily available MCP clients such as Claude Desktop, Cursor, and Windsurf. This reduces development time and costs, allowing developers to focus on creating innovative and valuable AI applications. The availability of pre-built MCP clients and servers also simplifies the integration process, making it easier for developers to experiment with different AI models and tools.
Thirdly, switching costs are collapsing. Because integrations are decoupled from specific models, organizations can migrate from Claude to OpenAI to Gemini, or even blend models, without the burden of rebuilding infrastructure. Future LLM providers will benefit from the existing ecosystem around MCP, allowing them to focus on enhancing price performance. This increased competition will drive down costs and improve the quality of AI models, benefiting both businesses and consumers. The ability to easily switch between models also allows organizations to choose the best model for a particular task, optimizing performance and efficiency.
Navigating the Challenges of MCP
While MCP offers immense potential, it also introduces new friction points and leaves some existing challenges unresolved.
Trust: The proliferation of MCP registries, offering thousands of community-maintained servers, raises concerns about security. If you don’t control the server, or trust the party that does, you risk exposing sensitive data to unknown third parties. SaaS companies should provide official servers to mitigate this risk, and developers should prioritize using them. These official servers should undergo rigorous security testing and audits to ensure they meet the highest standards of data protection. Users should also be educated about the risks of using untrusted servers and the importance of verifying the identity and security credentials of server providers.
Quality: APIs evolve, and poorly maintained MCP servers can easily become outdated. LLMs rely on high-quality metadata to determine which tools to use. The absence of an authoritative MCP registry reinforces the need for official servers from trusted providers. SaaS companies should diligently maintain their servers as their APIs evolve, and developers should favor official servers for reliability. Regular updates and maintenance are crucial to ensure that MCP servers remain compatible with the latest versions of APIs and that they provide accurate and up-to-date metadata. Automated testing and monitoring can help identify and resolve issues quickly, minimizing the risk of errors and disruptions.
Server Size: Overloading a single server with too many tools can lead to increased costs through token consumption and overwhelm models with too much choice. LLMs can become confused if they have access to too many tools, creating a less-than-ideal experience. Smaller, task-focused servers will be crucial. Keep this in mind when building and deploying servers. Strategically designing and deploying servers with a limited number of relevant tools can improve performance and reduce costs. Organizations should also consider using techniques such as tool selection and filtering to ensure that LLMs only have access to the tools that are necessary for a particular task.
Authorization and Identity: The challenges of authorization and identity management persist even with MCP. Consider Lily’s scenario where she grants Claude the ability to send emails, instructing it to "Quickly send Chris a status update." Instead of emailing her boss, Chris, the LLM might email every "Chris" in her contact list to ensure the message is delivered. Human oversight remains essential for actions requiring sound judgment. For example, Lily could set up a chain of approvals or limit the number of email addressees, adding a degree of control. Implementing robust authorization and identity management mechanisms is essential to prevent unauthorized access and misuse of AI tools. This includes using techniques such as role-based access control (RBAC) and multi-factor authentication (MFA) to ensure that only authorized users can access sensitive data and functionality. Organizations should also consider implementing audit logs to track user activity and identify potential security breaches.
The Future of AI: Embracing the MCP Ecosystem
MCP represents a paradigm shift in the infrastructure supporting AI applications.
Like any well-adopted standard, MCP is creating a virtuous cycle. Every new server, integration, and application strengthens its momentum. The more developers and organizations that adopt MCP, the more valuable it becomes, leading to further innovation and adoption. This network effect will drive the continued growth and evolution of the MCP ecosystem.
New tools, platforms, and registries are emerging to simplify the process of building, testing, deploying, and discovering MCP servers. As the ecosystem matures, AI applications will offer intuitive interfaces for plugging into new capabilities. Teams that adopt MCP will be able to develop products faster and with better integration capabilities. Companies that provide public APIs and official MCP servers can position themselves as integral players in this evolving landscape. Late adopters, however, will face an uphill battle to remain relevant. The ability to quickly integrate with new AI models and tools will be a key competitive advantage in the future, and organizations that fail to adopt MCP risk falling behind.

Organizations should implement robust monitoring and auditing systems to track the use of MCP-enabled AI applications and identify potential security breaches or misuse. This includes monitoring API calls, data access patterns, and user activity. Regular audits can help ensure compliance with governance policies and identify areas for improvement. Monitoring and auditing systems should be designed to detect anomalies and suspicious activity, and they should be integrated with incident response procedures to ensure that security breaches are addressed quickly and effectively. Organizations should also consider using security information and event management (SIEM) systems to aggregate and analyze security data from multiple sources.
Collaborating and Sharing Best Practices
The AI landscape is constantly evolving, and it’s essential for organizations to collaborate and share best practices for adopting and managing MCP. This can be achieved through industry forums, open-source projects, and collaborative research initiatives. By working together, organizations can collectively address the challenges and maximize the benefits of MCP. Collaboration and knowledge sharing can help organizations avoid common pitfalls, learn from each other’s experiences, and develop innovative solutions. Industry forums and open-source projects provide valuable opportunities for organizations to connect with other experts and to contribute to the development of the MCP ecosystem.
Embracing a Multimodal Approach
While MCP focuses on standardizing the connection between AI models and external tools, organizations should also consider adopting a multimodal approach to AI. This involves combining different types of AI models and data sources to create more comprehensive and robust solutions. For example, combining LLMs with computer vision models can enable AI applications that can understand both text and images. A multimodal approach can lead to more accurate and reliable results, and it can enable AI applications to solve more complex problems. Organizations should experiment with different combinations of AI models and data sources to identify the best solutions for their specific needs.
Focusing on Human-Centered Design
When developing MCP-enabled AI applications, it’s crucial to prioritize human-centered design principles. This means designing applications that are intuitive, accessible, and aligned with human needs and values. By focusing on human-centered design, organizations can ensure that AI applications are used responsibly and ethically. Human-centered design principles emphasize the importance of understanding user needs and preferences, involving users in the design process, and testing and iterating on designs to ensure that they meet user needs. AI applications should be designed to be transparent and explainable, so that users can understand how they work and why they make the decisions they do.
Fostering a Culture of Innovation
Finally, organizations should foster a culture of innovation that encourages experimentation and continuous improvement. This includes providing developers with the resources and support they need to explore new possibilities with MCP and to learn from both successes and failures. By embracing a culture of innovation, organizations can stay ahead of the curve and unlock the full potential of MCP. A culture of innovation encourages employees to take risks, to challenge the status quo, and to come up with new and creative ideas. Organizations should provide employees with the time, resources, and support they need to experiment with new technologies and to develop innovative solutions. They should also celebrate successes and learn from failures.
In conclusion, MCP is a transformative technology that has the potential to revolutionize the AI landscape. By standardizing the connection between AI models and external tools, MCP empowers developers to build more powerful and versatile AI applications. However, organizations must address the challenges of trust, quality, and server size to ensure the secure and responsible use of MCP.
