Canopii MCP Trust Index - Pros & Cons
Pros
- ✓Purpose-built for MCP-specific threats (tool poisoning, prompt injection) — not generic SCA
- ✓Per-version scoring closes the door on silent-update rug pulls
- ✓Public index is free to browse with full methodology disclosed
- ✓API enables CI gates and procurement automation, not just human lookup
- ✓Live endpoint verification separates real servers from squatted names
Cons
- ✗Enterprise/API pricing is 'by request' — no self-serve tiers published
- ✗~3,500 servers remain unverifiable at last snapshot
- ✗Scoring rubric is proprietary — reproducibility depends on Canopii's methodology page
- ✗Coverage is best-effort; brand-new servers may not yet be scored
- ✗Not a runtime guard — you still need policy enforcement in your agent host
Sinewave Agent Security Scanner - Pros & Cons
Pros
- ✓MIT-licensed and fully open source — no vendor gating on higher-value features
- ✓MCP-first design lets the coding agent scan its own output without a human in the loop
- ✓Purpose-built for agent-specific failure modes: prompt injection, hallucinated packages, tool spoofing
- ✓Claimed 97.7% benchmark precision, with 120 auto-fix templates to close the loop from detection to remediation
- ✓Lightweight @prooflayer variant is a viable pre-commit or CI check when the full scanner is too heavy
Cons
- ✗Precision claim (97.7%) is self-reported on the vendor's own benchmark, not an independent evaluation
- ✗Full scanner requires Python plus the AST toolchain — heavier install than a pure JS pre-commit hook
- ✗Auto-fixes are template-based; complex vulnerabilities may need human review after the rewrite
- ✗Rule coverage is language-broad but you should still verify depth for your specific stack
- ✗MCP server auditing scores are only as good as the point-in-time snapshot — a compliant server can still rug-pull on a later run
