scoremcp

Lighthouse for MCP servers. Score any server 0–100 for correctness and agent-readiness.

npx scoremcp node server.js
[ servers: 35 ][ avg: 85 ][ grade A: 7 ][ grade B: 19 ][ grade C: 8 ][ grade D: 1 ]
#nobody scores 100 — the median server is a B, and Microsoft ships both an A and a C. scoremcp checks the things that quietly break agent tool-use: invalid schemas, thin descriptions, missing safety annotations, and slow discovery. Run it before you ship — no account, no config, and it never invokes your tools.
