Most popular AI agents & MCP servers
Data as of 2026-07-19 · scores for week of 2026-07-20 · updated weekly
The established leaders of the AI agent and MCP ecosystem, ranked by total GitHub stars across every tracked, in-scope project. This is the popularity axis — the biggest, best-known projects — which is deliberately separate from trending: size is not momentum. A giant here may be flat this week; a small project may be accelerating fast on the trending page.
Methodology
- Total stars
- Projects are ranked purely by cumulative GitHub stars — the clearest signal of established adoption and mindshare.
- In-scope only
- Limited to projects whose identity is an MCP server, AI agent, agent framework, agent SDK, or AI infrastructure — general-purpose libraries that merely add an AI feature are excluded.
- Popularity ≠ trend
- This page never implies momentum. For what is growing right now, see the trending and emerging pages.
- Δ★ 7d for context
- The weekly star change is shown alongside, so you can see which leaders are still moving and which have plateaued.
All signals are computed from daily snapshots of stars, forks, releases, and npm/PyPI downloads, aggregated weekly. Every number above is traceable to a snapshot date — nothing is editorial, and rankings cannot be bought. Full details on the methodology page.
