One Year of Model Context Protocol: From Experiment to Industry Standard
How a November 2024 Launch Became the "USB-C for AI" in Just 12 Months
The Birth of a Standard
On November 25, 2024, Anthropic introduced something that would fundamentally reshape how AI systems connect with the world: the Model Context Protocol (MCP).
Created by Anthropic developers David Soria Parra and Justin Spahr-Summers, MCP addressed what engineers called the "M×N problem"—the combinatorial explosion of connecting M different AI models with N different tools or data sources.
The Problem MCP Solved
Before MCP, connecting ten AI applications to 100 tools meant potentially 1,000 different custom integrations. MCP reduced this to a simple equation: implement the client protocol once, implement the server protocol once, and everything works together.

Challenges and Growing Pains
Security Concerns (April-June 2025)
Identified issues include:
- Prompt injection vulnerabilities
- ~7,000 misconfigured servers exposed publicly (approximately half of all servers)
- Token misuse and credential exposure
- Tool permission escalation risks
- GitHub MCP server prompt injection weakness (May 26, 2025)
- Asana MCP server data exposure bug
Technical Challenges
- Version compatibility between rapid releases
- JSON-RPC serialization overhead (10-15ms latency)
- Limited multi-agent orchestration
- Complex authentication flows initially
Why MCP Won
Strategic Factors:
- Right Problem, Right Time: AI agents needed standardized connectivity
- Open and Neutral: Open-source with vendor-neutral governance
- Network Effects: Each new server added value to the ecosystem
- Strategic Adoption: OpenAI's March 26 endorsement created tipping point
- "Good Enough" Design: Sufficient and improvable
- Community-Driven: Contributions from students to enterprises
- Proven Patterns: LSP-inspired architecture felt familiar
Comparison to other standards:
- OpenAPI (Swagger): ~5 years
- OAuth 2.0: ~4 years
- HTML/HTTP: Much of the 1990s
- MCP: ~4 months (Nov 2024 to March 2025)
The Docker Parallel
MCP's trajectory mirrors Docker's early days: thousands of varying-quality containers created by the community, outpacing enterprise adoption but building unstoppable momentum. That low barrier to contribution served both projects' early phases perfectly.

Key Quotes from Industry Leaders
Mike Krieger, Chief Product Officer, Anthropic:
"MCP started as an internal project to solve a problem our own teams were facing. When we open sourced it in November 2024, we hoped other developers would find it as useful as we did. A year later, it's become the industry standard."
Jim Zemlin, Executive Director, Linux Foundation:
"We are seeing AI enter a new phase, as conversational systems shift to autonomous agents that can work together. Within just one year, MCP, AGENTS.md and goose have become essential tools for developers building this new class of agentic technologies."
"In just one year, MCP has evolved from an experiment to a widely adopted industry standard, highlighting the impact of open collaboration."
"We believe open standards are an important part of an agentic web—helping models work with tools and platforms more seamlessly. OpenAI has been contributing to the MCP ecosystem since early on."
Conclusion: The Standard We Needed
One year ago, connecting AI to data meant custom code for every integration. Today, MCP has become the "USB-C for AI"—a universal standard enabling any AI model to connect to any data source.
But MCP's story isn't about technology alone. It's about community, collaboration, and the power of open standards to accelerate an entire industry. It's about competitors setting aside proprietary interests to build shared infrastructure.
As MCP enters its second year under Linux Foundation stewardship, with support from the AI industry's biggest players and a thriving community of builders, the protocol that was "just an experiment" twelve months ago is now critical infrastructure for the AI age.
