This week's story

The top 10 saw its biggest shuffle since AgentRank launched. Seven of ten positions changed hands, driven by freshness signals catching up with repositories that had gone quiet since January. The scoring model weights recency of commits at 25% — stale repos, even popular ones, pay a price when maintainers go silent.

The winners are the tools maintainers are actively shipping: PrefectHQ/fastmcp (23.6K stars, Python) vaulted from #7 to #1 on the back of sustained commit velocity. Anthropic's own modelcontextprotocol SDKs — Go, Ruby, and the Inspector — all cracked the top 10 as official tooling matures.

The losers are last week's darlings that have coasted on star counts without shipping. CoplayDev/unity-mcp fell from #1 to #20 despite 7,003 stars. Stars without freshness is a liability in this index.

Tweet this week

Auto-generated tweet from this week's top insight:

The MCP top 10 just reshuffled hard.

@PrefectHQ/fastmcp: #7 → #1
CoplayDev/unity-mcp: #1 → #20

Freshness beats stars. Repos that stopped shipping paid the price.
