The AI Agent Ecosystem: March 2026 Report

We've indexed the entire AI agent ecosystem. Here's what the data tells us.

By the Numbers

Key Trends

1. MCP is winning the protocol war. 1080 MCP servers make up 49% of all indexed agents. The Model Context Protocol has become the de facto standard for agent-tool communication.
2. The framework explosion. With 550 frameworks indexed, we're seeing rapid innovation in how developers build agents — from LangChain to CrewAI to custom orchestration layers.
3. Developer tools dominate. The largest category is Developer Tools, reflecting that the current wave of agents is built by developers, for developers.
4. The long tail is massive. While top agents have thousands of stars, the majority of the ecosystem consists of specialized, niche agents solving specific problems.

What's Next

The agent ecosystem is growing exponentially. We expect to index 5,000+ agents by next month and 15,000+ by Q3 2026. The race is on to build the infrastructure layer for the agent economy.
