DeFiGuard MCP

DeFi protocol risk analysis tools for Claude Code, Cursor, and AI coding agents.

Detect rug pull patterns, honeypot indicators, flash loan vulnerabilities, MEV risks, and composability issues — before you deploy or invest.

Quick Start

Tools (5)

| Tool | Description | |------|-------------| | analyze_defi_risks | Full DeFi risk analysis of a Solidity contract | | analyze_defi_directory | Scan all contracts in a directory | | analyze_defi_snippet | Analyze a code snippet (no file needed) | | rug_pull_checklist | 10-point rug pull safety checklist with pass/fail | | list_defi_patterns | List all 22 detectable risk patterns |

Risk Categories (22 patterns)

| Category | What It Detects | Severity | |----------|----------------|----------| | Rug Pull | Mutable fees, unrestricted mint, liquidity drain, blacklist | Critical-High | | Honeypot | Transfer restrictions, bot mappings, sell blocks | Critical-High | | Flash Loan | Vulnerable callbacks, spot price oracles | High | | Composability | Unsafe ERC20 transfers, fee-on-transfer issues | Medium | | Governance | Single owner, upgradeable proxy without timelock | High-Medium | | MEV | Zero slippage, no deadline, sandwich attack vectors | Medium | | Token Standard | Non-standard decimals, missing events | Low-Info |

Protocol Detection

Automatically identifies known protocol patterns:

• Uniswap V2/V3 forks
• Compound forks
• Aave forks
• ERC-4626 vaults

The Quantum Shield Security Suite

| Package | Layer | Focus | |---------|-------|-------| | quantumguard-mcp | Cryptography | Post-quantum algorithm vulnerabilities | | smartguard-mcp | Smart Contract | Code-level vulnerabilities (reentrancy, overflow) | | defiguard-mcp | Protocol | DeFi-specific risks (rug pull, MEV, flash loan) |

Use all three for complete blockchain security coverage.
