OWASP-inspired launch gate for AI agents — scan MCP configs, test policies, simulate risk, and generate compliance evidence. Static-only, offline, no API keys.

Project description

🛡️ Pluto AgentGuard

Security launch gate for AI agents. Other tools scan configs — AgentGuard tests your policy against attack scenarios, simulates risk impact, maps results to an OWASP-inspired control framework, and generates launch evidence.

CI License: Apache-2.0 Python 3.10+ PyPI

What Makes This Different

MCP security scanners are multiplying fast (Snyk agent-scan, Invariant guardrails, AgentSeal). Most focus on config detection or runtime analysis. AgentGuard adds policy coverage testing, what-if simulation, drift detection, and launch evidence — all offline, no LLM or vendor lock-in:

Capability Scanners AgentGuard
Detect secrets & misconfigs statically (no server execution) 🟡 Varies aguard scan
Policy coverage testing (22 attack scenarios) aguard test
"What-if" risk impact before applying changes aguard whatif
OWASP-inspired control coverage (20 controls) aguard owasp
Launch readiness evidence packets aguard evidence
Baseline drift detection aguard baseline
Behavioral trace audit with approval model aguard monitor

📺 Interactive demo — see all 7 commands in action (clone repo, open in browser)

Quick Start (60 seconds)

pip install pluto-aguard

# Clone for examples
git clone https://github.com/arpitha-dhanapathi/pluto-aguard.git && cd pluto-aguard

# Scan a realistic insecure AI project — finds 18 real issues
aguard scan ./examples/demo-agent-project/

# Test your policy against 22 attack scenarios
aguard test --policy ./examples/agent-policy.yaml --attack-pack all

# Generate OWASP-inspired control coverage report
aguard owasp ./examples/demo-agent-project/

# Simulate policy changes — see risk drop before applying
aguard whatif --config ./examples/insecure-agent-config.yaml

# Generate launch readiness evidence packet
aguard evidence ./examples/ --config ./examples/insecure-agent-config.yaml \
  --policy ./examples/agent-policy.yaml

# Save baseline, detect drift later
aguard baseline create ./examples/
aguard baseline compare ./examples/

No cloud accounts. No API keys. Runs entirely locally.

Real-World Validation: 1,200 GitHub Configs

We scanned 1,200 real MCP configs from public GitHub repos (1,159 unique projects) using AgentGuard:

Metric Result
Configs scanned 1,200
Total findings 2,891
🔴 CRITICAL 0
🟠 HIGH 189
🟡 MEDIUM 169
ℹ️ INFO 2,533
Repos with HIGH findings 156 (13%)

What we actually found:

  • 189 remote MCP endpoints with no authentication configured
  • 169 unencrypted HTTP on non-localhost transport
  • Hardcoded secrets in a subset of configs
  • 2,533 informational items (capability inventory — shell access, browser automation, etc.)

Important context: Capability-related findings (e.g., a server having shell tools) are reported as INFO for awareness only. Per the MCP specification, human-in-the-loop enforcement is strictly a client/host responsibility, not the server's. See full methodology and results.

Commands

Command What It Does Maturity
aguard scan Static analysis — secrets, misconfigs, unsafe AI code patterns ✅ Stable
aguard test Policy coverage testing — 22 attack scenarios across 6 packs ✅ Stable
aguard owasp OWASP-inspired control coverage report (20 controls) ✅ Stable
aguard whatif Policy impact simulation — risk delta before applying changes ✅ Stable
aguard evidence Launch readiness packet with approval checklist 🔶 Beta
aguard baseline Security snapshot + drift comparison over time 🔶 Beta
aguard monitor Behavioral trace audit — replays tool calls against policy 🔶 Beta

aguard scan

Finds real issues in any AI project — no MCP configs needed. Detects eval/exec on LLM output, hardcoded secrets (18+ patterns), missing authentication on remote endpoints, Dockerfile misconfigs, unpinned AI deps, LangChain unsafe settings, system prompt leaks, and more.

$ aguard scan ./my-project/

  🔴 CRITICAL: Unsafe execution of LLM output: eval() (MCP05:2025)
  🟠 HIGH: Hardcoded OpenAI Key detected (MCP01:2025)
  🟠 HIGH: .env file not in .gitignore (MCP01:2025)
  🟡 MEDIUM: Unpinned AI dependencies (MCP04:2025)

  📊 Risk Score: 100/100 ██████████████████████████████████████████████████
  📋 Findings: 1 critical · 14 high · 3 medium

CI flags: --max-risk 50 / --fail-on high / --format sarif

aguard test

Tests 22 attack scenarios against your declared security policy. Reports what gets caught vs. what gets through. Pure policy coverage testing — no LLM needed.

⚠️ This tests whether your policy document would block each attack — not whether your actual LLM agent would resist it. Real agent resistance requires runtime testing against a live agent (planned for v1.2).

6 attack packs: prompt-injection, data-exfiltration, permission-escalation, approval-bypass, tool-poisoning, context-manipulation.

$ aguard test --policy agent-policy.yaml --attack-pack all

  ✅ PASS  PI-001  Direct instruction override        execute       Blocked
  ✅ PASS  DE-001  File export of sensitive data      file_write    Blocked
  ❌ FAIL  DE-004  SQL data dump                      sql_query     NOT caught

  📊 Results: 21 blocked · 1 missed · 22 total

  Recommended fixes:
    → Add sql_query to require_human_approval

CI flag: --fail-on-miss exits with code 1 if any attacks succeed.

aguard owasp

Evaluates 20 controls mapped to an OWASP-inspired control framework. Control IDs use a project-defined MCP01–MCP10 taxonomy that draws on OWASP LLM Top 10 and the emerging OWASP Agentic AI initiative, with MCP-specific extensions the existing standards don't yet cover.

$ aguard owasp ./my-project/

  ❌ MCP01:2025 Token Mismanagement: 3 failed, 1 passed
    ✗ AGC-MCP01-001: No hardcoded secrets
    ✓ AGC-MCP01-002: No static long-lived tokens
  ✅ MCP07:2025 AuthN/AuthZ: 2 passed
    ✓ AGC-MCP07-001: Remote servers have auth
    ✓ AGC-MCP07-002: HTTPS transport

  📊 Control Coverage: 9/10 risks
     Controls: 8 passed · 6 failed · 6 not tested · 20 total

aguard whatif

Simulates policy changes and shows risk score impact before applying them.

$ aguard whatif --config agent-config.yaml

  Current Risk Score: 100/100

  ✅ Restrict SQL to SELECT-only              → 68  (↓ 17%)
  ✅ Add human-in-the-loop for file ops       → 54  (↓ 34%)
  ✅ Add rate limits + timeout                → 48  (↓ 41%)

  💡 Apply all 3 → Risk drops to 38 (↓54%)

aguard evidence

Generates a launch readiness packet — risk summary, findings, tool permissions, policy coverage, required mitigations, and sign-off checklist. See examples/sample-launch-readiness.md.

aguard baseline

Save a security snapshot, compare later to detect drift.

aguard baseline create .               # Save current state
aguard baseline compare .              # What changed?
aguard baseline compare . --fail-on-drift  # CI: fail if new findings

aguard monitor

Replays agent action traces against a declared policy. Detects denied tool calls, unauthorized access, permission escalation, and missing/expired approvals.

aguard monitor --trace-file traces.jsonl --policy policy.yaml

Accepts OpenTelemetry JSONL or simple {"tool_name": "X", "tool_args": {}} format.

Risk Scoring

See docs/risk-scoring.md for the full scoring methodology — formula, weights, examples, CI threshold guidance, and limitations.

OWASP-Inspired Control Matrix

See docs/owasp-control-matrix.md for the complete mapping of 20 controls. Control IDs draw on OWASP LLM Top 10 (LLM01–LLM10) and introduce MCP-specific extensions (MCP01–MCP10) for risks the existing standards don't yet cover.

Roadmap

  • v0.1–v0.5 — Scanner, monitor, whatif, evidence, baseline, CI gates, SARIF, HTML reports
  • v0.8 — Policy coverage testing (17 scenarios, 5 attack packs)
  • v0.9 — OWASP-inspired control framework (20 controls, coverage reports)
  • v0.9.1 — Context manipulation pack (context stuffing, multi-turn confusion, indirect injection, RAG poisoning), supply-chain manifest poisoning scenario
  • v1.0 — Runtime proxy / tool-call firewall (observability on live tool calls without full red-team harness)
  • v1.1 — Multi-framework adapters (LangChain, CrewAI, AutoGen)
  • v1.2 — Live agent testing (send adversarial inputs to running agents)
