What we measure
Each server is started in an isolated sandbox on our own machine, never in production.
Read the methodology01
Context tax
Tool definitions are resent to the model on every turn. We tokenize them, so you know what a server costs before it eats your context window.
02
Security signals
Secrets, dependency CVEs, install scripts and prompt-injection patterns in tool descriptions — each finding listed with its evidence.
03
Startup & size
Cold-start time, tools/list latency, memory and install footprint, measured with no network and a read-only filesystem.
