What is the purpose of this directory?

This directory serves as a comprehensive, deep-analysis report and meta-directory of the top 100 API (Application Programming Interface) and MCP (Model Context Protocol) hubs. Our goal is to provide developers, product managers, and decision-makers with a clear, data-driven ranking to help them navigate the complex ecosystem of digital integrations.

How are the rankings determined?

The rankings are generated using a proprietary scoring system that evaluates platforms on a 100-point scale across four weighted categories: Platform Maturity & Features, Ecosystem Scale & Network Effects, Business Model & Market Strategy, and Financial Momentum & Industry Recognition. You can find a detailed breakdown of the methodology in the report sections on the main directory pages.

What is the difference between an API and an MCP?

APIs are designed for human developers to connect applications and services. MCP is an emerging open standard designed specifically for AI agents to communicate and interact with external tools and data sources. While APIs built the current "API Economy," MCP is laying the groundwork for the future "AI Agent Economy."

Is this directory free to use?

Yes, access to the directory, rankings, and the accompanying report is completely free. Our mission is to make this critical information accessible to everyone in the tech community.

How often is the data updated?

We aim to review and update the rankings and analysis on an annual basis to reflect the rapid changes in the market, including new funding rounds, acquisitions, and shifts in platform strategy.
