The Model Context Protocol (MCP) is quickly becoming the "USB-C for AI applications," providing a standard way to connect AI models with external data sources and tools.

Since Anthropic introduced MCP in November 2024, it has grown from a technical specification into a thriving ecosystem with significant commercial opportunities. This growth is similar to the API tooling market that emerged around companies like Postman and Kong.

We're witnessing history repeat itself, but accelerated. Just as the API economy spawned billion-dollar infrastructure companies in the 2010s, MCP is creating similar opportunities today, only faster and with AI at the center. The parallels are striking: where Postman democratized API testing and Kong built the gateway layer, we're now seeing MCP-native companies emerge across hosting, infra, development tooling, authentication, and marketplace discovery.

The early indicators are compelling. Over 1,000 community-built MCP servers have emerged within six months of launch, while enterprise adoption is being driven by companies like OpenAI, Stripe, Intercom, Notion, Replit, and Sourcegraph.

The MCP ecosystem: 8 key categories

Rather than cataloging individual MCP servers (which every SaaS will eventually have, like APIs today), this market map focuses on the infrastructure and tooling companies that enable MCP adoption. These are the "picks and shovels" of the MCP ecosystem - the platforms, tools, and services that make it easy for any company to create, deploy, secure, and manage production-ready MCP servers.
