MCP at 18 months: the server ecosystem hits critical mass
In one sentence Eighteen months after launch (November 2024), Model Context Protocol consolidates: thousands of public servers, confirmed cross-vendor adoption, first stable official registry.
MCP (Model Context Protocol) was announced by Anthropic in November 2024 as an open standard to connect models to tools and data. Initially met with skepticism: "yet another standard nobody will use". Then in 2025 it exploded: OpenAI adopted it in March, Google in summer, Microsoft integrated it in Copilot and VS Code, GitHub embraced it.
In May 2026 — 18 months later — it's clear MCP is the "USB-C of agents". Thousands of public servers (databases, SaaS, file systems, specific APIs), a stable central registry, standard authentication (OAuth), and every serious IDE or agent framework supports it natively.
For agent builders: you no longer write custom integrations per tool. You look up an MCP server, plug it in, done.
For SaaS vendors: having an official MCP server has become a market requirement, like having a REST API was in 2015.
For security: maturation includes disclosure of historical vulnerabilities, audits, and best practices around sandboxing.
