MarketNow's L1.9 Prompt Injection Screening lacks false positive rate data
MarketNow's L1.9 system, recently renamed 'Prompt Injection Screening', uses regex rules for threat identification. However, the provided evidence explicitly states that it 'lacks measured false positive rates'. This is a critical gap for a security system intended to be a pre-admission filter, as unquantified false positives could lead to legitimate user actions being blocked.
MarketNow will release metrics on L1.9 false positive rates within 60 days
Given the explicit mention of lacking false positive rates for the L1.9 Prompt Injection Screening system, and the general trend of increased transparency and security focus in recent MarketNow updates, it is plausible they will prioritize measuring and releasing these metrics. This would be a logical next step to validate the effectiveness of their L1.9 layer.
Schema drift in MCP servers is concentrated and appears deliberate
Analysis of MCP servers shows that schema drift is not widespread but confined to a small subset of active servers. Crucially, there have been no instances of reversion, suggesting that the observed changes in tool contracts are intentional modifications rather than accidental drift. This implies a need to monitor the specific servers exhibiting these changes.
