Summary
A reliability check before you trust a server.
Stars measure popularity; this measures whether calls succeed. A score below 30 reads as risky, and most of every score comes from real runtime outcomes rather than static inspection.
What it is
A hosted MCP server that keeps reliability scores for other MCP servers. Scores run 0-100 and combine a static signal with real success rates, latency and error patterns reported by agents after they call.
What you get
- A trust score and reliability metrics for any MCP server
- Success or failure reported back after a call, feeding the score
- Top-rated servers listed by category
- Behavioural baselines for a tool category
- A check on whether a server's current behaviour is anomalous
- A 30-day trust trend for one server
- New servers registered, and network-wide statistics
