Show HN: G0 – AI 에이전트를 위한 제어 계층(스캔, 테스트, 모니터링, 준수)

Discover · Assess · Test · Monitor · Comply AI agents make decisions, call tools, and access data autonomously. g0 answers three questions every team must ask before shipping: what agents do you have, what can they access, and can you prove they're under control? npx @guard0/g0 scan ./my-agent npm install -g @guard0/g0 # Install globally g0 scan ./my-agent # Assess a local project g0 scan https://github.com/org/repo # Assess a remote repository g0 scan . --upload # Upload to Guard0 Cloud (free) npx @guard0/g0 scan . # npx (no install) Assess your agent codebase — every finding mapped to OWASP, NIST, ISO, and EU AI Act: Scan Results ──────────────────────────────────────────────────────────── Path: ./my-banking-agent Framework: langchain (+mcp) Files scanned: 14 Agents: 2 Tools: 4 Prompts: 2 Duration: 1.2s Security Metadata ──────────────────────────────────────────────────────────── API Endpoints: 3 (2 external) DB Accesses: 5 (4 unparameterized) PII References: 8 (6 unmasked) Call Graph Edges: 23 Findings ──────────────────────────────────────────────────────────── CRITICAL Shared memory between users [AA-DL-046] [AGENT REACHABLE] Memory in main.py is shared without user isolation. main.py:8 > ConversationBufferMemory Fix: Isolate memory per user_id or session_id. Use namespaced memory stores. Standards: OWASP:ASI07 HIGH System prompt has no scope boundaries [AA-GI-001] [AGENT REACHABLE] System prompt lacks role definition, task boundaries, or behavioral constraints. main.py:21 > Assistant helps the current user retrieve the list of their recent bank transact Fix: Add explicit role definition, allowed actions, and behavioral boundaries. Standards: OWASP:ASI01 | AIUC-1:A001 | ISO42001:A.5.2,A.8.2 | NIST:MAP-1.1,GOVERN-1.2 HIGH Database tool without input validation [AA-TS-002] [AGENT REACHABLE] [LIKELY] Tool "query_db" in tools.py accesses a database without apparent input validation. tools.py:34 Fix: Use parameterized queries and validate all input before database operations.
