We Scored 39,752 MCP Servers — Here's What We Found

We built an open-source platform that scores MCP servers across three independent dimensions. After scoring nearly 40K tools, the data revealed some uncomfortable truths — and one big problem with how we were measuring quality.

The Problem

Our first scoring system evaluated tools on static analysis alone: schema correctness, token efficiency, description quality, security, and install reliability. Five dimensions. One composite quality score.

The result: 85.7% of all tools scored Grade B.

No differentiation. No motivation to improve. A platform that tells everyone "you're average" is a platform nobody needs.

The Fix: Additive Scoring Model

We rebuilt the system from scratch. The new model recognizes that real-world adoption matters just as much as code quality.

Composite Grade = Quality Score (0-100) + Community Bonus (0-60) + Trust Bonus (0-30)
