Severity Finding Location
Low
Dependencies not version pinned Supply Chain
requirements.txt uses loose version constraints (>=) for anthropic and mcp packages. While not malicious, version pinning would improve reproducibility and prevent potential supply chain issues.
anthropic>=0.39.0
mcp>=1.1.0
→ Pin exact versions in production use (e.g., anthropic==0.39.0) to ensure consistent behavior
