feat(catalog): AGT MCPSecurityScanner for catalog drift and tool poisoning - #112
Merged
Conversation
- catalog/scanner.py: CatalogScanner wraps AGT MCPSecurityScanner: scan_catalog() — registers all tools at load time (SHA-256 fingerprinting) and scans for hidden instructions (P2.1 tool poisoning) and typosquatting (P4.1); check_drift() — check_rug_pull() on notifications/tools/list_changed (P4.2 rug-pull detection); graceful fallback if agent-os-kernel not installed - 10 unit tests: clean scan, flagged threat, all tools registered, rug-pull detection, graceful no-op without AGT Closes #58 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
