The tech world has been buzzing about MCPs (Modular Communication Protocols), but what exactly are they and why are they going viral? In a recent podcast episode, Professor Ross Mike broke it down into simple terms, explaining both the technical aspects and the exciting potential for startup opportunities.
MCPs represent a major step forward in combining Large Language Models (LLMs) with tools and services, making these AI systems significantly more capable and scalable. Here’s an overview of MCPs, why they’re a game-changer, and what they mean for entrepreneurs, developers, and businesses.
What Are MCPs?
At its core, MCPs are a standardized layer that bridges LLMs with external tools and services, enabling smoother communication and integration.
Professor Ross Mike explained the problem MCPs solve:
- LLMs Alone Are Limited: By themselves, LLMs can predict text and answer questions, but they cannot perform external tasks like sending emails, accessing databases, or controlling applications.
- Tools Enable More Capability: Developers have traditionally added tools like APIs, databases, and search engines to extend LLM functionality. For example, tools let LLMs summarize emails, fetch data, or automate workflows.
- The Problem with Tools: Integrating multiple tools with LLMs becomes cumbersome and inefficient, especially at scale. Developers often need to “glue” various tools manually, leading to fragile systems prone to breaking with updates or changes.
Enter MCPs—a universal “translator” that creates a seamless connection between an LLM and various tools or services. MCPs standardize how LLMs interact with external systems, making integrations more cohesive and scalable.
Why MCPs Matter
“MCPs provide structure and order where there used to be a chaotic mess,” explains Professor Mike. He likened MCPs to a universal translator that ensures tools, LLMs, and services all “speak the same language.”
With MCPs:
- LLMs Become Smarter: They can access complex tools and perform advanced tasks more efficiently.
- Integration Becomes Simpler: Developers don’t need to customize every connection. MCPs handle the translation.
- Easier Collaboration on Standards: Service providers (e.g., database platforms, productivity tools) can create MCP-compatible protocols, enabling universal compatibility.
For example, if you wanted your LLM to read a Slack message, analyze it, and take immediate action—such as sending an email or updating a spreadsheet—MCPs would streamline that entire process.
The MCP Ecosystem
Ross highlighted the four core components of the MCP ecosystem:
- MCP Client: The “front-facing” side that connects to LLMs. Examples include platforms like Tempo or Cursor.
- MCP Protocol: This is the standardized communication framework that links the MCP Client to the MCP Server.
- MCP Server: Constructed by service providers, the server ensures their external tools or databases are MCP-compatible.
- External Services or Tools: These are the tools (e.g., APIs, databases, search engines) that the LLM accesses via the server.
This structure distributes responsibility, allowing service providers to construct MCP-compatible systems that developers and users can easily integrate.
Challenges with MCPs
Although MCPs are promising, they’re not without obstacles:
- Setup Complexity: Early adopters report challenges setting up MCP servers, often involving complicated file transfers and configurations.
- Reliance on Standardization: MCPs are in their infancy, and if service providers don’t adopt the standard, integration becomes fragmented.
- Evolving Market: Just as MCPs gain traction, another competitor standard could emerge, leaving developers to shift focus again.
“We’re at an early stage,” Ross notes. “But if MCPs finalize into stable protocols, they could unlock enormous potential.”
Startup Opportunities with MCPs
Professor Ross Mike sees major potential for both technical and non-technical entrepreneurs:
For Developers
- Create an MCP App Store: Developers could build a platform where businesses can browse available MCP servers, deploy them easily, and integrate them with LLMs.
- Focus on Tools: There’s room for innovation by building niche tools that leverage MCP compatibility, such as workflows for specific industries (e.g., healthcare, finance).
For Non-Technical Users
Non-technical entrepreneurs are encouraged to:
- Monitor Emerging MCP Platforms and Standards: Understanding the space now can put you ahead as MCP adoption grows.
- Prepare for Integration: When MCP-backed platforms reach maturity, they can help non-technical founders automate processes quickly without hiring large engineering teams.
“There’s no need to make big moves yet,” Ross advises. “Just pay attention, learn, and wait for the market to finalize standards. When the time comes, you’ll hit the ground running.”
The Bigger Picture
Technological progress often follows patterns of standardization. From HTTP to SMTP, breakthroughs in protocols have consistently driven mass adoption of transformative technologies. MCPs are poised to do the same for LLMs, moving us closer to the “Jarvis-level” AI assistants we’ve long dreamed of.
By simplifying the integration process, MCPs position LLMs to handle increasingly complex tasks while making them accessible to a broader audience. The result? A future where individuals and businesses, regardless of technical skill, can tap into the immense power of AI with unparalleled ease.
