53 mentions across 5 sources · 50% positive — mixed (averaged across 5 sources)

Hacker News, YouTube, Product Hunt, GitHub, Lemmy

What users praise

  • • Purpose-built for MCP traffic in AI coding assistants.
  • • Real-time proxy intercepts tool calls and responses for analysis.
  • • Detects prompt injection, credential theft, and command injection.
  • • Dual detection: LLM analysis plus deterministic signature matching.

What frustrates them

  • • Default mode sends data to external LLM provider—trust trade-off.
  • • Setup can be non-trivial; GitHub issues document configuration failures.
  • • Each MCP call is proxied and scanned, potentially adding latency.
  • • Free tier caps at 250 transactions—insufficient for regular use.
