We're witnessing a genuine paradigm shift in AI capabilities. The emerging Model Context Protocol (MCP) fundamentally changes what AI systems can do by giving them something they've never had before: the ability to take action in the world.
This isn't just another incremental improvement – it's the moment AI transitions from "smart chatbot" to something much closer to JARVIS. And for startups, this creates an entirely new landscape of opportunities.
Before diving deeper, it's worth clarifying an important distinction:
Agentic AI refers to autonomous systems that can plan and execute multi-step tasks with minimal human oversight. These systems have their own internal "agenda" and decision-making capabilities.
Model Context Protocol (MCP), by contrast, is a framework that enables AI models to interact with external tools, APIs, and data sources through standardized interfaces. MCP is essentially the "connective tissue" that allows AI to access and manipulate real-world systems.
The relationship is synergistic: Agentic AI provides the reasoning and planning capabilities, while MCP provides the means to execute those plans in the real world. Together, they create something powerful enough to deserve the JARVIS comparison.
The fundamental limitation of AI systems until now has been their inability to do anything beyond generating text. They could tell you what to do, but couldn't actually do it for you.
MCP shatters this constraint by creating standardized protocols for AI to:
This shift from "advisor" to "actor" represents a quantum leap in what's possible with AI.
The most compelling near-term applications of MCP aren't customer-facing – they're internal. In my startup advisory work, I'm seeing massive efficiency gains in these key areas:
MCP-enabled systems can:
A startup founder I advise recently implemented this for their 30-person team and eliminated an estimated 20+ hours of weekly manual synthesis work.
The sales process is ripe for MCP transformation:
One B2B SaaS startup reduced their sales team's administrative work by 40% through MCP implementation, allowing reps to spend dramatically more time on actual selling.
Perhaps the most impressive ROI comes from automating complex document creation:
A founder shared that their team reduced RFC response time from 3 days to 4 hours while increasing the technical quality by having more comprehensive and consistent documentation.
Based on patterns I'm seeing across dozens of startups in the Keiretsu Forum ecosystem, MCP will create three distinct waves of opportunity:
The first wave focuses on automating existing workflows using a single MCP server with simple automations. These startups will see 5-10X efficiency improvements by connecting AI to their existing tools. Think of it as "IFTTT on steroids" – using natural language to orchestrate previously manual processes.
Example: A marketing team using a single MCP server to automatically analyze campaign performance, draft social posts, and adjust ad spend across platforms based on real-time performance.
The second wave involves integrating multiple MCP servers to create more sophisticated systems. These startups will reimagine user experiences around AI-first principles, creating interfaces and workflows that would be impossible with single-server approaches.
Example: Devin AI exemplifies this approach – it connects specialized AI systems across development, testing, and deployment workflows, allowing them to collaborate on complex software projects. Devin can review conversations in Slack channels to extract requirements, integrate directly with Vercel and GitHub to manage deployments, and automate testing processes. This multi-agent approach allows for more sophisticated reasoning and execution than any single system could achieve, saving development teams dozens of hours weekly on routine tasks.
The third wave will create entirely new product categories that have no direct analog in today's market. These will be products built from first principles around what's possible when AI can both reason about and act in the world.
Example: Remember how smartphones enabled Uber to exist? MCP will enable similar category-defining companies we can't yet imagine.
The biggest challenge with MCP implementation is what I call the "cold start" problem. An MCP-enabled AI is only as powerful as the systems it can access and the actions it can take.
This creates three distinct approaches for startups:
Most successful MCP startups will likely start with approach #2 (integration) to validate their core thesis, then gradually move to approach #1 (vertical stack) as they identify the highest-value components to own.
What's crucial to understand here is that startups need to expand their thinking about their audience. Your target users aren't just humans anymore – they're also AI agents. This means designing your APIs and systems not just for human developers but for AI consumption as well. The startups that thrive will create systems that are easily discoverable, well-documented, and accessible to both human developers and AI agents. Think of it as SEO for AI – making your capabilities easily understood and integrated by autonomous systems.
Based on what I'm seeing in startups across the Keiretsu Forum:

The MCP ecosystem is evolving rapidly. Glama.ai maintains an excellent directory of MCP servers at glama.ai/mcp/servers, which tracks the growing number of specialized systems. Some notable entries include:
Exploring this ecosystem helps founders understand the building blocks available for creating their own MCP implementations.
For founders looking to capitalize on this shift:
Most importantly, the JARVIS moment isn't coming – it's here. The question is whether your startup will be defined by it or left behind by it.
