Limits

Limit	Why it matters
It checks what you send it	Your client or gateway must call verify before each use (MCPGate can)
The poisoning screen is pattern-based	Paraphrases get through; its 0.21% false-alarm figure was tuned on the corpus it was measured on
It compares definitions, not behaviour	A server that keeps its description but changes what the tool does is not caught here
Live since 2026-11-02 18:49Z	health reports 1.1.0; the poisoning screen and drift checks were re-run live
Our own testing	No independent review
