└────────────────┴───────┴────────────────────────────────────────────────────────────────┘

A GHOST agent is an AI system making real API calls — consuming tokens, potentially accessing sensitive data — with no corresponding source code, deployment record, or owner. No static analysis tool finds this. No SIEM alerts on it. AgentDiscover Scanner finds it in under 60 seconds by watching the runtime and cross-referencing it against your codebase simultaneously.

Your engineering team thinks they know what AI is running. The GHOST classification is what they don't know.

What makes this different

Most security tools tell you what's in your code. AgentDiscover Scanner tells you what's actually running — and crucially, what's running that has no business being there.

👻 GHOST AGENT DETECTED
   Workload:    trading-bot (Deployment/default)
   Connected:   api.openai.com — LIVE
   SaaS:        openai — confirmed active connection
   Source code: None found in scanned repositories
   Owner:       Unknown — no deployment record, no code review

👻 GHOST AGENT DETECTED
   Workload:    shadow-agent (Pod/kube-system)
   Connected:   api.anthropic.com — LIVE
   SaaS:        anthropic — confirmed  |  gcp — active socket
   Blast radius: HIGH (cloud provider access confirmed)
   Source code: None found in scanned repositories
   Owner:       Unknown — no deployment record, no code review

Every detected agent also carries a SaaS blast radius — a live-observed map of which services it's actively connected to, derived from network traffic, not just configuration files:

crewai-agent (CONFIRMED)
  saas_connections:
    anthropic: confirmed  ← active_connection observed
    github:    medium     ← open socket
  risk_flags: [cloud_credentials_present]
  blast_radius: 70/100

confirmed means the connection was live-observed during the scan — not inferred from a config file.

Agent classifications

Classification	What it means	Risk
👻 GHOST	Runtime AI activity — no source code found	Critical
✅ CONFIRMED	Detected in code AND observed running	High
⚠️ UNKNOWN	Found in code, not yet observed at runtime	Medium
🖥️ SHADOW AI	Known app using AI without governance	Medium
☠️ ZOMBIE	Was active, no longer observed	Low

Quick start

# macOS (recommended)
brew install python@3.12 osquery pipx
pipx install agent-discover-scanner
pipx ensurepath && source ~/.zshrc   # add ~/.local/bin to PATH

# Linux (Debian/Ubuntu)
sudo apt-get install -y python3 osquery
pip3 install agent-discover-scanner

# Linux (RHEL/Fedora)
sudo dnf install -y python3 osquery
pip3 install agent-discover-scanner

# Windows (PowerShell — elevated)
winget install Python.Python.3.12
winget install osquery.osquery
pip install agent-discover-scanner

macOS: never use sudo with the installer — Homebrew refuses root and osquery silently fails. Use pipx to avoid Python environment conflicts. If agent-discover-scanner is not found after install, run pipx ensurepath and restart your terminal.

Then run your first scan:

agent-discover-scanner scan-all ~/projects --duration 30

To verify all layers are working before your first real scan:

agent-discover-scanner --version
osquery --version
which agent-discover-scanner   # macOS: should show ~/.local/bin/agent-discover-scanner

To upload results to the DefendAI platform:

agent-discover-scanner scan-all ~/projects \
  --platform \
  --api-key YOUR_API_KEY

How it works

AgentDiscover Scanner runs four detection layers simultaneously and correlates them into a single agent inventory. Each layer sees something the others can't.

Layer 1 — Source code analysis

Static analysis of Python and JavaScript/TypeScript. Detects LangChain, LangGraph, CrewAI, AutoGen, direct OpenAI/Anthropic/Gemini API usage, and any HTTP client targeting LLM endpoints. Handles import aliasing and indirect usage patterns. Generates SARIF output for CI/CD integration.

Layer 2 — Live network monitoring

Passive observation of outbound connections to AI providers — OpenAI, Anthropic, Google Gemini, Mistral, Cohere, Azure OpenAI, AWS Bedrock, and vector stores. No packet capture. Identifies which process is making each connection, enabling per-agent SaaS attribution.

Real scan output:

[DETECT] Google AI connection from Mail (PID: 776) → generativelanguage.googleapis.com:993
[DETECT] OpenAI connection from Microsoft Edge Helper (PID: 4172) → api.openai.com:443
[DETECT] Anthropic connection from Cursor Helper (PID: 61436) → api.anthropic.com:443
[DETECT] OpenAI connection from OneDrive (PID: 96089) → api.openai.com:443

Layer 3 — Kubernetes runtime

Kernel-level visibility into pod behavior via Tetragon. Identifies which workloads are actively making AI calls — including workloads with no corresponding source code. Works with any CNI. Falls back to Kubernetes API discovery if Tetragon is unavailable.

When Layer 1 (code) and Layer 3 (K8s runtime) both detect the same agent, it becomes CONFIRMED:

Detection Coverage:
┏━━━━━━━━━━━━━━━┳━━━━━━━━┓
┃ Layers        ┃ Agents ┃
┡━━━━━━━━━━━━━━━╇━━━━━━━━┩
│ layer1,layer3 │ 2      │  ← CONFIRMED: seen in code AND running in K8s
│ layer1        │ 3      │  ← UNKNOWN: code found, not yet observed at runtime
└───────────────┴────────┘

Layer 3 limitations

Layer 3 (eBPF via Tetragon) is Linux-only. On macOS and Windows developer machines, Layer 3 is skipped automatically — the scan continues with Layers 1, 2, and 4. The K8s API monitor path works on all platforms and requires only kubectl with cluster read access.

Layer 4 — Endpoint discovery

Scans developer machines, CI/CD runners, and workstations via osquery. Finds installed AI packages, desktop AI applications (ChatGPT Desktop, Claude Desktop, Cursor, GitHub Copilot), active connections, browser-based AI usage, and VSCode extensions.

Cross-layer correlation

After all layers run, the correlator builds a unified agent identity. An agent seen in code (Layer 1), confirmed running in K8s (Layer 3), and observed making network calls (Layer 2) is a single correlated identity — not three separate findings.

Agents present at runtime with no Layer 1 match become GHOST agents.

SaaS blast radius detection (v2.3.0+)

After correlation, each agent receives a saas_connections profile built from all four layers:

{
  "detected":  ["anthropic", "gcp", "github"],
  "confirmed": ["anthropic"],
  "evidence": {
    "anthropic": ["active_connection", "open_socket"],
    "gcp":       ["open_socket"],
    "github":    ["vscode_extension_detected"]
  },
  "confidence": {
    "anthropic": "confirmed",
    "gcp":       "medium",
    "github":    "medium"
  },
  "has_cloud_provider": true,
  "has_llm_provider":   true
}

High-risk agent detection (v2.4.0+)

The scanner detects autonomous agent platforms that carry systemic security risk by design — not misconfigurations, but architecture.

OpenClaw (formerly Clawdbot/Moltbot) is the primary target. It has full filesystem access, terminal execution, email and messaging integration, and runs as a persistent background daemon. CVE-2026-25253 CVSS 8.8. Gartner: "insecure by default." Microsoft: "treat as untrusted code execution."

Detection uses corroborated signals — never a single port number:

🚨 HIGH-RISK AGENT CONFIRMED: OpenClaw
   Autonomous agent with system-level access — filesystem,
   terminal, email, and messaging integration.
   Capabilities: filesystem, terminal, email, browser, messaging

MCP server detection (v2.4.0+)

MCP (Model Context Protocol) is the integration layer between AI agents and enterprise SaaS. Supported by Claude, ChatGPT, Gemini, Copilot, Cursor, and VS Code.

The scanner detects MCP servers across all AI clients and classifies each by publisher verification:

⚠ Local MCP script detected — unknown code with tool access
⚠ Unverified MCP server: filesystem (Community/Unknown) — not from a verified publisher
⚠ Unverified MCP server: mcpfw (Unknown) — not from a verified publisher

✓ Verified: @salesforce/mcp-server (Salesforce official)

Supported clients: Claude Desktop, Cursor, Windsurf, VS Code, Gemini CLI, OpenAI Codex, Continue.dev, Zed, and project-level MCP configs.

Non-developer detection: Financial analysts connecting ChatGPT Teams to Salesforce via UI leave no local config file. The scanner detects this via Layer 2 network traffic — the only tool that catches this pattern.

Risk prioritization in reporting (guidance):

Unverified MCP server → HIGH
MCP filesystem access → HIGH
MCP + production environment → CRITICAL
OpenClaw + GHOST → CRITICAL

Daemon mode

Run continuously as a background service, updating the agent inventory every 30 seconds:

agent-discover-scanner scan-all ~/projects \
  --daemon \
  --output ~/defendai-results \
  --platform \
  --platform-interval 5    # upload to platform every ~2.5 minutes

Note: --daemon runs until you press Ctrl+C. Use --output ~/defendai-results (or any user-writable path) — avoid /var/log/ which requires root. If running as root, ~/projects resolves to root's home directory, not yours. Always run without sudo.

With --platform, the daemon syncs to the DefendAI platform every N correlation cycles (default: every 5 cycles ≈ 2.5 minutes) and always uploads a final snapshot on shutdown.

Linux — install as a systemd service:

sudo bash deployment/systemd/install-service.sh ~/projects
systemctl status defendai-scanner

Customizing known applications

By default, the scanner classifies common desktop applications (browsers, Office 365, Cursor, Slack, Claude Desktop, etc.) as Shadow AI rather than GHOST when they make AI API calls.

Browser-based AI usage (claude.ai, chatgpt.com, copilot.microsoft.com) is detected via Layer 4 browser history — these are classified as Shadow AI automatically. Note that Layer 4 reads the browser's committed history database, not the current active session, so a tab open right now may not appear until the browser flushes its history.

To add your own internal tools:

mkdir -p ~/.defendai
echo "my-internal-ai-tool" >> ~/.defendai/known_apps.txt
echo "company-llm-client" >> ~/.defendai/known_apps.txt

See docs/known-apps-example.txt for the full format.

When connected to the DefendAI platform (--platform flag), the tenant-managed list is downloaded automatically on startup and merged with your local overrides.

DefendAI platform integration

The scanner is the discovery layer. The platform is where discovered agents become governed agents.

agent-discover-scanner scan-all ~/projects \
  --platform \
  --api-key YOUR_KEY \
  --duration 30

When connected to the platform, each scan triggers the correlation engine which builds a living identity map across every machine, every environment, and every scan:

Agent identity resolution — the same CrewAI agent on a laptop, in staging K8s, and in prod K8s is recognized as one agent at different lifecycle stages
Behavioral drift detection — agent added has_code_execution=true since last week? That's a signal. Platform tracks it.
Cross-machine intelligence — agent seen on 3 machines and crossed from dev into prod? Automatic risk escalation.
SaaS blast radius — platform aggregates confirmed SaaS connections across all scans and computes blast radius score.

After a few scans, the DefendAI platform report shows:
