The “USB-C for AI” Moment Has Arrived
In late 2024, Anthropic made a bold move that’s reshaping how AI systems connect to our digital world. They introduced the Model Context Protocol (MCP) as an open standard that acts as a universal connector between large language models and external data, tools, and environments.
The concept is brilliantly simple: instead of building custom integrations for every AI assistant and every data source, create one standardized protocol that any AI can use to discover and interact with any tool. Think of it as the “USB-C for AI” – one standard interface that eliminates a mess of proprietary connectors. I originally called it the “ODBC for AI”, but that never caught on!
What’s remarkable isn’t just the technical elegance of MCP, but the speed of adoption. By February 2025, what began as a niche technical specification exploded into an ecosystem with over 1,000 community-built connectors. This rapid growth stems from a rare moment of industry alignment – Anthropic launched it, but OpenAI and Google quickly embraced it as the de facto standard.
As someone who’s watched decades of enterprise standards battles, this level of cooperation is unprecedented in the AI space.
The MCP Architecture: Simple Yet Powerful
The architecture follows a client-server model that should be familiar to enterprise developers. A host application (whether an IDE, chatbot, or any AI-powered tool) connects with multiple MCP servers, each exposing different tools or data sources.
Communication happens over secure channels using Server-Sent Events (SSE) for streaming responses. This simple yet flexible structure enables everything from basic file access to complex multi-agent orchestration.
The Major Players Reshaping the Ecosystem
MCP is remarkable in how quickly it has gained favor. Proponents range from global IT giants to open-source projects on GitHub.
1. Anthropic’s Foundation (Late 2024)
Anthropic deserves credit for both creating MCP and immediately treating it as an open community standard. They released a comprehensive specification with SDKs in Python and TypeScript, demonstrating their commitment to openness.
Claude Desktop launched with native MCP client support, showing how an AI assistant could maintain context across multiple tools instead of being siloed per integration. They provided reference connectors for file systems, Git, Slack, GitHub, and databases – establishing a pattern others would follow.
Early enterprise adopters like Block (Square) and Apollo validated MCP in real business environments, while developer tools like Zed, Replit, and Codeium began enhancing their AI features using the protocol.
2. OpenAI’s Market Validation (Early 2025)
The ecosystem accelerated dramatically when OpenAI’s Sam Altman publicly endorsed MCP, announcing implementation “across [their] products.” This move bridged what had been competing AI ecosystems, allowing ChatGPT and Claude to share the same pool of tools.
OpenAI’s integration spans their Agents SDK, the forthcoming ChatGPT desktop app, and their Responses API – effectively enabling all OpenAI-powered agents to leverage the entire universe of MCP servers. This is a pivotal shift from their proprietary plugins approach toward an open ecosystem.
When the market leader adopts your standard, you know you’ve hit an inflection point.
3. Google’s Enterprise Push
Google Cloud’s Vertex AI platform followed with their Agent Development Kit (ADK), which explicitly supports MCP to “equip agents with your data using open standards.” They paired this with an Agent2Agent protocol for inter-agent communication, creating a comprehensive framework for building multi-agent systems in enterprise environments.
This combination of MCP (for agent-to-tool connectivity) and Agent2Agent (for agent-to-agent collaboration) opens fascinating possibilities for complex business workflows. Google’s approach is particularly notable for its partnerships across 50+ industry players (including Salesforce), showing their commitment to making MCP work in heterogeneous enterprise environments.
In the usually conflicted world of IT Giant co-opetition, Google also relaunched Google Agentspace at Google Cloud Next. Agentspace can be positioned as a competitor to Salesforce Agentforce, using overlaid AI technology to deprecate the value of Salesforce Agentforce integration.
4. Microsoft’s Developer Integration
Microsoft has woven MCP deeply into their developer tools ecosystem. They partnered with Anthropic to release an official C# MCP SDK and integrated it into GitHub Copilot and Semantic Kernel (SK), Microsoft’s AI orchestration framework.
Microsoft’s innovation lies in bringing MCP to the core of software development. They’ve transformed tools like VS Code into AI-augmented environments where the AI not only suggests code but actively executes tasks. GitHub Copilot can now run terminal commands, modify files, and interact with repositories via MCP interfaces.
Their embrace of open standards (combined with their market reach through GitHub, VS Code, and Azure) is accelerating community-driven innovation.
Beyond the Tech Giants: The Expanding Ecosystem
While the major players provide much of the infrastructure, the true innovation often happens at the edges. Several projects are pushing MCP’s boundaries in fascinating ways:
Enterprise Java Integration (Spring AI MCP)
The Spring Framework team at VMware recognized that Java developers needed first-class MCP support. They launched Spring Boot starters for MCP clients and servers, making it trivial to create MCP interfaces for enterprise Java applications.
This bridges the gap between cutting-edge AI and traditional enterprise software, allowing Java developers to expose existing systems (databases, message queues, legacy applications) to AI agents through MCP.
Integration-as-a-Service (Composio)
Composio emerged as a managed hub of MCP servers, offering 250+ ready-to-use connectors spanning cloud apps, databases, and more. This “MCP app store” approach means developers can connect their AI agents to hundreds of services without hosting or coding each connector themselves.
Their innovation is in the business model: providing integration-as-a-service for AI agents and handling the complexity of authentication and maintenance.
Multi-Agent Collaboration (CAMEL-AI’s OWL)
The CAMEL-AI research community’s “Optimized Workforce Learning” (OWL) framework demonstrates how multiple specialized AI agents can collaborate on complex tasks, with each agent equipped with different MCP tools.
Their approach mimics human teamwork, allowing agents to divide labor, share information, and coordinate. OWL ranked first in the GAIA multi-agent benchmark with an average score of 58.18, proving that multi-agent systems with MCP tools outperform isolated approaches.
Physical World Integration (Chotu Robo)
Perhaps most fascinating thing is seeing MCP extend beyond the digital realm. An independent developer, Vishal Mysore, created “Chotu Robo” – a physical robot controlled by Claude AI through MCP. The robot uses an ESP32 microcontroller with MCP servers exposing motor commands and sensor readings.
This project demonstrates MCP’s versatility in connecting cloud AI services to edge devices, potentially opening new frontiers in IoT and robotics.
The Economic Implications of Tool-Using AI
From my perspective as an analyst focused on Virtual Employee Economics, MCP represents a critical infrastructure layer that will accelerate the deployment of AI agents functioning as human-equivalent labor. By standardizing how AI connects to enterprise systems, MCP dramatically reduces integration costs. This is historically one of the biggest barriers to AI adoption.
We’re witnessing the birth of a new economic paradigm where AI agents can be quickly equipped with specialized tools, much like how human employees are given access to company systems. The difference is scale and speed. Once one agent can use a tool via MCP, any agent can.
This has profound implications for how organizations will structure their digital workforces. Rather than building bespoke AI assistants with limited, hardcoded capabilities, companies can now deploy flexible agents that discover and use tools as needed.
Salesforce’s MCP Dilemma: Fighting the Inevitable?
In the rapidly evolving MCP landscape, Salesforce finds itself in a particularly vulnerable position. While the company has made significant investments in its Agentforce platform, they’ve been notably reluctant to embrace the MCP standard that their competitors are rapidly adopting. This hesitation is understandable but potentially shortsighted. MCP fundamentally challenges Salesforce’s embedded AI strategy by enabling AI assistants to maintain context across multiple tools seamlessly, rather than being siloed per integration.
The economics are compelling: overlay solutions can feed enterprise data into various AI models at a fraction of the cost of embedded AI add-ons like Agentforce, which can run $30-$100 per user per month. As MCP becomes the universal standard for connecting AI with data sources, Salesforce risks being relegated to merely a system of record while the real intelligence and user engagement happens through overlay AI platforms that can seamlessly access Salesforce data alongside other enterprise systems.
Salesforce’s reluctance to fully embrace open standards reflects a classic innovator’s dilemma – protecting their proprietary ecosystem while the market shifts beneath them. For enterprise customers already invested in multiple systems beyond Salesforce, MCP’s promise of integration without vendor lock-in presents an increasingly attractive alternative to Agentforce’s walled garden approach.
The Road Ahead: Questions and Opportunities
While MCP’s adoption has been remarkably fast, several questions remain:
- Security and Governance: As MCP evolve from localhost to server-based, how will enterprises manage permissions and audit trails for AI agents accessing sensitive systems via MCP?
- Tool Discovery: With thousands of MCP servers available, how will agents intelligently select the right tools for a given task?
- Multi-Agent Orchestration: As complex workflows span multiple agents and tools, what patterns will emerge for coordination and error handling?
- Business Models: Will we see specialized MCP connectors become valuable IP, or will the ecosystem remain primarily open-source?
- Overlay AI Data Access: How will companies like Salesforce, SAP and others react to MCP servers which relegate them to mere data containers?
For enterprise leaders, the message is clear: MCP is becoming the standard way AI will interact with your systems. Planning for this integration now will position your organization to leverage increasingly sophisticated AI agents in the coming years.
For developers, the opportunity is tremendous. Building MCP servers for unique data sources or specialized tools could create significant value as the ecosystem expands.
As this standard continues to mature throughout 2025, we’re likely to see even more innovative applications across industries. Companies that understand and embrace MCP first will have a significant advantage in deploying effectively tool-using AI.
